GPS Timing Receivers Comparaison at the SLR in Helwan
Original language description
We are presenting the comparison test of several types of the Global Positioning System (GPS) timing receivers. The Smart GPS Clock type HP58503B has been used as a reference. The influence of the satellite selection strategy in the case of the Trimble Navigation 5000A has been identified. The performance of the low cost GPS receivers - OEM modules by Garmin has been tested in detail. All the timing receivers have demonstrated a capability to provide the epoch reference within 100 nanoseconds compared to the reference. The dependence of the timing spread and accuracy of the Trimble 5000A on a satellite selection strategy has been identified. Surprisingly, the low cost OEM modules by Garmin provided the same accuracy for the cases, when an sensor was installed with an non-obscured view of the entire sky. These OEM sensors may provide a simple and cheap back up alternative to the GPS timing receivers once the clear non-obscured view on the sky can be guaranteed.
