Webb- Satellite clock errors - Receiver clock errors DGPS cannot correct for GPS receiver noise in the user’s receiver, multipath interference, and user mistakes. In order for DGPS to work properly, both the user’s receiver and the DGPS station receiver must be accessing the same satellite signals at the same time. WebbThe broadcast orbital solution error and satellite clock error are estimated using the data collected by the receiver from 02:00 hours to 02:39 hours with an epoch interval of 15 seconds. During this observation period of 39 minutes (total of 157 epochs) out of 31 satellites, 9 (02, 05, 12, 15, 18, 21, 25, 26, 29) satellites were visible.
