  • USA 52 - . Payload: RME. Mass: 1,040 kg (2,290 lb). Nation: USA. Agency: SDIO. Class: Military. Type: Strategic defense satellite. Spacecraft: RME. Decay Date: 1992-05-24 . USAF Sat Cat: 20497 . COSPAR: 1990-015B. Apogee: 281 km (174 mi). Perigee: 261 km (162 mi). Inclination: 43.1000 deg. Period: 89.90 min. Relay Mirror Experiment; also known as Losat-R. RME validated stabilization, tracking, and pointing technologies for Strategic Defense Initiative (SDI) missions through a credible demonstration of a space-based relay mirror system. The Wideband Angular Vibration Experiment (WAVE) measured low-level angular vibrations affecting performance of acquisition, tracking, and pointing systems. The experiment demonstrated that a laser beam can be accurately relayed from the earth to an orbiting satellite 450 kilometers away and then back to a 3-meter target on the ground. It achieved relay beam pointing accuracy which was 16 times better than the technical requirement. WAVE demonstrated the capability to discern platform disturbance amplitudes of a few nanoradians at discrete frequencies and is therefore a candidate to fulfill similar requirements for future ATP experiments.
