AIR FORCE AERO PROPULSION LAB WRIGHT-PATTERSON AFB OH
On 2 September 1972, the Navy launched a navigational satellite of the Transit series. This satellite, which was called TRIAD during its development, has a radioisotope thermal generator RTG for its main power source however, it has an auxiliary power source consisting of four experimental hardened solar panel segments. Another one of the experiments on board the spacecraft is a set of six solar cell modules designated the Environmental Survey Panel ESP. This report will describe the pre-flight tests that were conducted on the solar power experiments, the results of those tests, and the flight data that are available.
