GPS Time Synchronization

GPS technology can be used as an inexpensive, readily available method for high precision timing and measurement of event simultaneity. [1] However, knowledge of the error inherent in the timing and position accuracy of the GPS module being used is necessary for the use of such devices in this capacity. Research has been done on the timing accuracy of a GPS module (Leadtek GPS-953W) as compared to a different baseline module (Motorola UT-Plus Oncore). In this paper we independently investigate the timing and position accuracy of a Leadtek GPS-9543LP receiver by a different method: comparing the signal to that of an identical module.
