How Bad Receiver Coordinates Can Affect GPS Timing

H. Chadsey

Abstract:	Many sources of error are possible when GPS is used for time comparisons. Some of these errors have been listed by Lewandowski. Because of the complexity of the system, an error source could have more than one effect. This paper will present theoretical and observational results by offsetting a receiver's coordinates. The calculations show how an error as as small as 3 meters in any direction can result in a timing error of more than 10 nanoseconds. The GPS receiver must be surveyed to better than 0.2-meter accuracy for the timing error to be subnanosecond.
