GPS-35

The Global Positioning Satellite (GPS) 35 was launched by the U.S. Department of Defense in August 1993 in the B-4 orbital plane. This satellite is a Block IIA configuration and is know as SVN35 or PRN05. GPS-35 is configured with a small panel of optical retroreflectors, enabling it to be tracked by the international network of SLR stations. A primary objective of the GPS Laser Retroreflector Experiment (GPS/LRE) is to provide an independent, high-precision measurement of satellite position that, when compared with GPS pseudoranges, can unambiguously separate satellite-position errors from onboard atomic clock errors.
