Current Constellation GPS Satellite Ground Received Signal Power Measurements

Clyde Edgar, David B. Goldstein, and Philip Bentley

Abstract:	As the GPS constellation has matured, it has become a mixed constellation of Block II, IIA and IIR space vehicles. There has been considerable interest expressed as to how similar the different generations of space vehicles are in terms of received signal power, one of the key performance factors. A summary of the most recent satellite received signal level power data will be presented along with a description of the data collection equipment and signal processing techniques used to collect it. The GPS on orbit measurements are collected at a large aperture antenna test facility located in Stanford, California. The summary data demonstrates how similar the different generations of space vehicles are in terms received signal power.
