Summary
OPS 8701 (DSP 10), also known as DSP F10, is an Early Warning satellite owned by AFSD and operated for the US military. Launched on March 6, 1982 from LC40 at AFETR using a Titan IIIC launch vehicle, this satellite has been in stable orbit since March 7, 1982. It was manufactured by TRW with dimensions of 7 meters in length, 2.8 meters in diameter, and spans 7.7 meters. The spacecraft's dry mass is 1050 kg, with a launch mass of 1180 kg. Its mission involves Early Warning using the DSP 13 payload powered by four deployable fixed solar arrays and batteries. The satellite has a cylindrical shape with four panels (Cyl + 4 Pan) and a motor MRE-4 for propulsion. It was designed to operate for about three years, but specific details regarding its operational lifespan and transmission frequencies are not provided in the given data.
