Overview

Executive Summary

This wiki contains an online users guide for the Delorme-Earthmate PN-20 hand held GPS unit. The user guide encompasses a basic manual as well as product information and troubleshooting. This Wiki effectively demonstrates why collecting information via the user base of a product could ultimately lead to a better structure for basic product references than a user manual. A majority of the information on this page will have been collected by first hand experience by operating the device. Some information was taken from the users manual, and some was found from other existing sources.

For our group, this was the first time any of us have created and maintained a wiki, so this project will also allow most of us to gain useful knowledge on how the creation, structure, accessibility, and practicality of a wiki as a useful tool on the internet.

The Delorme Earthmate PN-20

] Released in January 2007, the Delorme PN-20 was a new and innovative handheld GPS platform. The device's distinguishing feature is its ability to download and store topographic, aerial, and satellite images all of which can be downloaded from Delorme. With this ability the device is able to offer multiple views of the same GPS location (nautical charts, satellite imagery, topographic views, etc.). It features a brightly lit screen that works well in total darkness or in direct sunlight, offering a maximum usability in a wide range of lighting conditions. Built with the true outdoors-man in mind, the PN-20 features an impact resistant, waterproof housing and sturdy construction. The device also has user friendly large buttons which are good for use with winter gloves in cold winter environments. Featuring the latest developments in GPS technology the device touts outstanding signal acquisition and retention which means it will work well in your car or even in the densest tree covered jungles. The NP-20 also offers a sizable amount of onboard memory, 75MB, allowing the user to create and store up to 50 routes or 1000 user-defined waypoints. In all the Delorme NP-20 is a very capable handheld GPS unit, rich in features and in adaptable software.

Getting Started

Uploading Maps

The PN-20 comes with map software including road maps and topographical maps. These should be installed before the PN-20 is used for the first time. The device does not have the capacity to hold every map available so the user must select the maps they wish to upload. By using the software that comes with the PN-20, select maps can be downloaded to the SD card provided by Delorme, and inserted into the device.

To install the memory chip, remove the back of the battery compartment. Under where the battery lies is a holster for the memory chip. Once inserted, the batteries can be installed as well. (Delorme, 2007)

Installing Batteries

The PN-20 requires two AA batteries to operate. A travel accessory can be purchased which comes with a rechargeable single lithium-ion battery pack. To install the batteries, unscrew and remove the back panel of the device and insert the batteries according to the positioning indicated by the PN-20 inside the compartment. (Delorme, 2007) Be sure to reattach the back panel in order for the device to work properly.

Charging the PN-20

If you are using the travel pack, you can charge the single Lithium-ion battery while it is in the unit by connecting the unit to your computer via the USB cable. The device must be powered on for it to charge and will not charge as fast as removing the battery and charging it in its wall unit.

The Basics

Basic buttons

GPS-buttons.jpg
Button Function
In/Out Use this button to zoom in and out of a map. Hold In or Out to see the maximum detail in or maximum zoom out. Use these two buttons to scroll through lists one page at a time as well.
Page The page button cycles through the various enabled pages that the PN-20 features. The order of the pages follows: satellites, Maps, Compass, Trip Info, and Route directions.
Quit The quit button will halt the current process or page backward through the various pages.
Find The find button (magnifying glass) can be used to search for waypoints, addresses, coordinates and other points of interest to the PN-20. It can be used by searching locations by name, or locations close to the center of the map.
Mark Waypoint Labeled as a pushpin, this button can be used to mark the current GPS location as a saved waypoint. It will save information such as its location, elevation, and will plot a point on the map showing its placement.
Power Used to turn on and off the GPS PN-20. To turn it on, press and hold for 1.5 seconds. To turn it off, press the power button followed by the enter button to confirm shutdown. To cancel the shutdown press quit.

While the unit is on, press and hold the power button for 2 seconds, this enables the backlight to be adjusted up or down by pressing the left or right arrow. The backlight can also be turned off by pressing and holding the power button for 3 seconds while the unit is on.

Enter The Enter button is used to select on screen menu items as well as points on the map. Pressing enter will select the item of which the cursor is placed upon.
Menu The menu button accesses various functions both specific to the current page being utilized, and general to the PN-20 unit. The top of the menu will show specific items to the active page. The bottom will show the general items.

Basic functions


Map panning

To pan a map which is currently being viewed, move the cursor to the edge of the map (using the arrow buttons) in the direction you wish to pan. Once at the edge of the map, hold the directional button in the same direction and the map will adjust its orientation.

The maps will automatically pan if using the navigation/route page to orient your current position as the center of the map.

Map object information

By placing the cursor over a map object, you can:

1. Press enter to obtain any available information.

2. Press enter to view a menu of available objects to view. (For multiple objects on the same point)

3. Highlight and select "Mark" to save as a waypoint.


Navigating or Tracking?

The most widely used function of the PN-20 is for navigation or tracking. The difference between the two is technically small, but the implications are wide.

Navigating allows you to use the PN-20 to follow a predetermined route with directions and a colored path on the digital map.

Tracking will happen when the PN-20 is being used out of navigation mode, and will track the path being taken by the PN-20 with a trail on the digital map.

Ways to use the PN-20

The PN-20 is a tool which can be widely applied to various aspects of different hobbies, jobs, situations and scenarios. These are only a few of the endless posibilities of how the PN-20 can be utilized. What can YOU do with it?

Geocaching

Geocaching is a popular GPS treasure hunting game where the sought out points are obtained and then hunted down like a scavenger hunt. They are gaining in popularity all over the world and can be found all over the country.

Mountain biking

By planning out a bike trail, or using the PN-20 to see a satellite image map to select the best trails for your trip, mountain biking can be an easy, fun experience for even the most novice rider.

GIS data managing

GIS, also known as a geographical information system or geospatial information system, is any system for capturing, storing, analyzing and managing data and associated attributes which are spatially referenced to Earth. (http://en.wikipedia.org/wiki/GIS, 2007) These can include elevation measuring, farm soil monitoring, urban planning and logistics.

Camping

Use the PN-20 to mark your favorite camping sites as waypoints. Close by streams, trails, peaks, and food sources could also be marked as waypoints and saved under your favorite camping location. You can even locate the closest emergency response location.

User Guide

Menu Pages

The Satellites Page

Satellite.jpg

This gps unit, runs off of satellites in order to find the correct position. It has three different kinds of fixes, 2-D, 3-D, and WAAS. When the gps reads no fix, it says it does not have sufficient satellite information to find your position.

A 2-D connection means that the unit has a connection with the a satellite. This typically means that it is only connected to three satellites and it might not have a the same accuracy as a 3-D connection. The best way to fix this would be to move until you get a better signal and can obtain a 3-D connection.

A 3-D connection is on the device when it is connected to at least three satellites and also has no overhead obstructions (trees, buildings, tunnels, etc...).

If a WAAS connection is obtained, a small icon will appear on the gps screen. The advantage of this connection is that it has up to five times greater accuracy than the normal 2-D or 3-D connection. This technology is only available for use in the United States.

In this device there are two options for viewing satellite strength and what you actually are connected to, they are called Satellite Constellation or Signal Graph. The satellite constellation allows you to the satellite identification numbers that you are connected to. In this mode there are satellite shaped icons that show each of their positions relative to the device's current position. The signal graph also allows you to see the identification numbers of the connected satellites. Rather than seeing satellite icons, they are represented through a bar graph of sorts. This graph tells the user which satellite has the best connection (larger the bar, greater the connection).

Both in the satellite constellation and signal graph the icons are color coordinated for ease of recognizing the quality of data. The different colors are red, green, and blue, red being the poorest, while blue is the signal that you want. In particular, red indicates that the gps receiver is tracking the satellite, but it is not receiving any information. The green icon means that the gps is tracking the satellite, and it is able to be used as a navigation device. The blue icon is much the same as the green except that if the blue is available, that means there is WAAS corrections available.

As far as accuracy goes with the gps, the actual unit with a good connection can locate within 10 meters. The WAAS feature is technology that was developed by the FAA and this changes the normal +/- 10 meters into +/- 3 meters or any spot, provided you have the connection that allows for this (Blue icon).

The Maps Page

Map.jpg

When the gps device has obtained either a 2-D or 3-D connection, the unit fixes on your position. This means that if a connection is achieved, then when you look at the map, your exact location will appear. If a connection is not available and the maps page is brought up, then the unit will display the last location that a signal was present. On the map itself your location will be indicated by an arrow and that arrow too is color coded to distinguish what kind of fix the unit has. The colors displayed are red, blue, yellow, and green. The red means that the gps unit has no gps signal, the blue indicates that the device is in Track Playback mode or Simulate Navigation mode. If a yellow or blue arrow appears on your screen, than the unit has a 2-D or 3-D signal respectively. When viewing the maps, a North arrow can be shown by selecting the Heading Up, or Course Up option.

This particular device comes with a base map showing high level world and United States coverage. Some other maps/data types that are compatiable are:

  • High-resolution cities
  • Color Aerial Imagery, Aerial Imagery
  • USGS Quads
  • NOAA Nautical Charts
  • Satellite Imagery
  • DeLorme Topographic Data
  • World Base Data

Once the maps are on the screen, if you want to hide some of the data on screen to make the map larger, you go through the "menu" and select "info fields", and then select "hide info fields". If you would want to keep the information fields but change what is within them you go to "menu", "info fields', then select "change info fields" and then from there you select what you want to be displayed.

A feature of the maps that can be used on this gps is finding the distance of a perimeter or line and area of a polygon. To do this go to "menu" and select "measure distance", from this you then use the cursor on the screen to select points to find a distance and once it is closed the area will be calculated.

With this gps, you can download maps externally from the device and then put them on the unit. Once on the unit, you can sort which maps you want to see and which you do not. To do this go to "menu", "map setup", and select "data management". Once your in this option you can select what maps you want to hide and which you want to display.

The Compass Page

Compass.jpg

The compass page is a digital version of a physical floating needle compass. As the heading changes, the compass rotates so that the heading is always pointed up. Another option that can done is to set a heading or a waypoint and the compass arrow will stay true to that setting. If you were to stray off course, the compass feature would also guide you back onto the route. Using the gps as a compass is a very easy task.

From the main menu, go to the compass page and from there use the arrows to select a waypoint or plotted course for the compass to track.

This feature is handy because it allows you to be able to follow a course and if you were to go off track, it the needle would then point you back in the direction needed to stay on course.

The Trip Info Page

While viewing the Earthmate GPS PN-20 Trip Info Page, there will be eight areas of information displayed on the screen in normal view (or three areas in large text mode). Default areas of information will include the "Coodinates:Lat/Lon", "Trips:Odometer", "Trip Moving", "Trip Stopped", "Trip Total", "Speed", "Max Speed" and "Avg Speed."

  • "Coodinates:Lat/Lon" will show you your current latitudinal and longitudinal coordinates based on direction and bearing.
  • "Trips:Odometer" shows the total distance you have traveled from start to your current location.
  • The "Trip Moving" section will show the time, from start to present, that you and your GPS have been moving.
  • The "Trip Stopped" section shows the amount of time that you and your GPS have stopped during your current trip, if you are not moving in any direction, the "Trip Moving" field will stop and the "Trip Stopped" section will begin again.
  • "Trip Total" is the combination of both the "Trip Moving" time and the "Trip Stopped" time; it is the overall time from which you started your trip to the current time.
  • "Speed" section will show your current traveling speed in mph,
  • "Max Speed" will show your fastest speed obtained during your trip
  • "Avg Speed" shows your average speed during your whole trip.


The stated eight areas of information are default settings but can be changed to your individual preferences.

From here you can either save/delete the waypoint, center the map around the waypoint or create a route using the waypoint by using the arrow keypad to highlight "Mark"/"Delete", "View" or "Route" buttons and pressing <enter> respectively.

The Waypoints Page

The bottom most button on your GPS, the one that looks like a push pin, is the "Mark" button. It can be used to create waypoints on your map. After you create each waypoint you can choose your own name, symbol, coordinates, elevation, time/date and original comments for that specific waypoint.

Customizing/Editing Your Waypoint

  • Press the button to create your waypoint. Then, to customize your waypoint use the arrow keys to highlight the piece of information you would like to change and press <enter>. Now, using the arrow keys again, scroll through the available options and hit <enter>. If you are creating text, be sure to hit <enter> after each letter. Once you have your waypoint customized you can edit it using the same steps as described.


You can also use the "Mark" button to average your waypoint. Using this, the GPS will take multiple readings around your waypoint and average them to increase the accuracy of the readings.

Averaging Your Waypoint

  • Averaging can only be done at a current waypoint so first, press the <Mark> button to create your waypoint. Then, highlight the "Ave" button and press <enter>. This will show you the readings the GPS has taken at your specific point. The more readings you take the less error there will be, thus repeating this step as many times as possible will give you your most accurate readings. Once you finish with your readings, use your arrow keys to highlight "Ok" and press <enter>, and "Save" and again press <enter>.


When you have known waypoints that you have created and you may also want to find the distance and bearing from them to your current location.

Viewing Your Waypoints

  • Go to the "Waypoint" page. From here you will see all of your current waypoints that you have marked previously. If you highlight one and press <enter> you will find all the information on that specific waypoint including the bearing and distance to that waypoint from your current location.


The main purpose of the waypoints, and essentially the GPS, is to be able to find routes to your desired location.

Creating a Route With Your Waypoint

  • Select a waypoint either from the "Map" page or the "Waypoint" page, and press <enter>. Now, select the "Route" button, press <enter> and then the "Navigate" button, and press <enter>. This will create and calculate the best route available.


Centering your waypoint on your map is the best way to see what landmarks are around your waypoint.

Centering Your Waypoint

  • Select your waypoint, either from the "Map" page or the "Waypoint" page, and press <enter>. Then, simply highlight "View", press <enter> and your map will be centered on your waypoint.


Old waypoints may want to be deleted to reduce clutter and create better simplicity.

Deleting Waypoints

  • Select your waypoint, either from the "Map" page or the "Waypoint" page, and press <enter>. Then, highlight "Delete" and press <enter>. Here you have time to confirm that you are deleting the correct waypoint. If it is correct, use your arrow keys to highlight "Yes" and press <enter>.
  • To delete all of your current waypoints press <Menu>. Now select "Delete All Waypoints" and a confirmation table will again arise. If you wish to proceed, use your arrow keys to highlight "Yes" and press <enter>.

The Routes Page

This page will allow you to create a route and then view its directions by several methods:

  • From your current location to a waypoint
  • From you current location to a Find search result
  • Between two waypoints
  • Between two Find search results
  • Between a way point and a Find search result


To get started create a new route on the Routes Page by selecting <new>:

  • You should replace the default name with something familiar to you by highlighting the <route name> field and using the keypad to enter a new identifier.
  • To add a route point select <add point> and then use the Find functions (link to find page here) to specify your preference. Simply hit <add> to add the search result as a point on route. Continue repeating this step until you have entered all the desired route points.
  • Once all the route points have been selected select <calculation method> and choose from <road/direct> depending on how you would like to travel; <road> will follow the route using known roads while <direct> will connect each point with a straight line.
  • Finally, select<navigate> and if the calculation is successful the route will display on the map page (add link)


To use your GPS like a car’s navigation system use the ‘simulate navigation’ feature. This will make the route display on the map and the device beep at each applicable turn. To activate this feature:

  • Select the desired route from the Route Page.
  • Press <menu> and select <simulate navigation> by pressing <ok>. This will cause the curser to go into simulate mode and plays the route on the map.
  • To end a simulation press <menu> and <stop simulation>.


Helpful Hints:

  • Active routes display in the Routes Page with red text.
  • You can also select <use map> to select a route point using the map instead. You may find this function easier to use because you can simply continue to pan and select points instead of searching the database.
  • To exit Navigation mode press <menu> and select <stop navigating>.
  • To exclude your current GPS location from the route points simply select <current position> and then <remove>.

The Tracks Page

When you first use your PN-20 is will automatically have a default setting that enables GPS tracks. This feature essentially leave a “breadcrumb trail” as you travel, recording and storing your progress. In it’s most basic form the trail will display on your GPS as a dotted line, however the color of the line indicates multiple things:

px200
px200


  • If the line is green, the GPS has a 3-D fix.
  • If the line is yellow, the GPS has a 2-D fix.


It is important to note that this feature will operate continuously with no input from the user, but only so long as the GPS can acquire a fix. If the connection is interrupted no trail will be displayed and the last know point will be marked by a red line.


The Tracks Page will allow you to do one of four things
Option Function Procedure
SAVE Stores the current track to memory for later use. To save an active track simply highlight <save> on the Tracks Page and press <enter>. The track name, color, and comments can all be changed by first selecting the track, and then choosing their respective tabs and inputting information. You may also view, follow, or delete the track from this page as well.
CLEAR Deletes the current track. Hit <clear> on the Tracks Page
FOLLOW THE CURRENT TRACK Reverses a track so you can follow your footsteps backwards. From the Tracks Page select a saved track, then hit <follow>.
VIEW/FOLLOW AN EXISTING TRACK Allows user to revisit and follow a previously saved track. Selecting the desired track from the main page will display the details of that trip (red text indicates visibility on the map). Simply hit <view> and the track will display on your GPS, at which point you may use any of the above functions; when you are done return to the detail page of that track and select <hide>.


The PN-20 also provides you with the ability to choose how tracking data will be collected and stored. There are two ways by which information is logged, points are based on either time or distance. Time based logging provides detailed results, but uses more points and memory. Distance based logging takes longer to track, but is useful for long distances. Your PN-20 manual has detailed instructions on how to change this setting.

The Sun/Moon Page

Sun-Moon-page.jpg


The Sun/Moon Page can be used to view information about the rise and fall of earth’s celestial bodies including the various phases of the moon. The images displaying in the center of your screen represent the current conditions based on the time and date settings which are displaying at the top.

Unit is not being accurate - The necessary amount of satellites may not be located by the PN-20.

Project conclusion

Conclusion remarks. Each person should write their own reflection.

  • Casey - This project was a good experience in many ways. I enjoyed taking on an open ended project based on creating a wiki. I thought the basis for our article that we as a group created was outlined really well. It brought together information from other wikis, product manuals, and some information you can only get by personal observation. Because of this I think we have created a superior document of which can be used as a general reference for this very specific product. As a project, it was interesting to participate in a project where most of the work was done separately verses together as a whole. It was interesting to communicate almost solely by email, yet be able to put together a clear and concise set of information.
  • Gabrielle - The idea to create a wiki over a written report has allowed us to really think about the wiki user's needs, which is what lead to our main goal of developing an easy-to-use wiki manual for the product. We have taken information from the existing manual received with the product and put it into a very user-friendly page along with additional helpful information. I believe that individuals could definitely use this wiki to learn about how to operate this product correctly.
  • Keith - I feel like this project helped me learn in two or three differnet areas. First of all, it helped me understand the basics on how to use this particular piece of equipment. Second, I learned about how to use and create a wiki. Lastly, it helped me learn about how to put together a project over the internet. This wiki was not only a learning experience for ourselves but I believe it could actually be put into the real wiki and help others with the GPS understand better how to use it then with the original manual that came with it.
  • Sarah - This was one of those projects that I feel really helps me with my other classes. I never would have set out to learn how to create a wiki on my own, but having done it now I see many applications to use it again in the future. What I particularly like about our project is that it can function as a real wiki and be incredibly useful as an alternative to the user manual.
  • Jon - While I did learn how to operate the Delorme GPS unit and got to understand how useful GPS can be, both for recreational and business purposes, I found that what I learned more about was how to use a wiki. I learned how to move pictures around, insert hyperlinks, and format articles. This is something i would not have learned on my own and it seems as though this may be a very useful skill in the future.
