Circuits to add a passive ranging capability to the Interferometric Landmark Tracker (ILT) to form a Passive Range Interferometer Sensor (PRAIS) were built and tested in the laboratory. The laboratory test data were used in a Monte Carlo simulation to demonstrate the performance of the PRAIS Navigation System in a highly eliptical orbit and a synchronous (1 deg inclination) orbit. Navigation accuracies better than 1000 ft and attitude accuracy better than 10 arcsec were indicated by the analyses. (Author)
