	===Receiver clock errors ===		===Receiver clock errors ===
		+
		+	Due to the inability to perfectly synchronize all of the satellite clocks there is a discrepancy amongst time readings. The clocks are within 3 nanoseconds of each other but due to the speed of light and other bias such as traveling through the ionosphere clock errors can account for a 1 meter inaccuracy in position.
