Summary
COSMOS 1870, also known as Kosmos-1870, is a radar satellite (modified crewed spacecraft) launched by ZIKH on July 25, 1987, from the TYMSC launch site using LC200/40 and the Proton-K launch vehicle. It has dimensions of 7 meters in length, 4.1 meters in diameter, and a span of 15 meters. The satellite's dry mass is 18,500 kilograms, which is also its launch mass. Equipped with S-band Synthetic Aperture Radar (SAR) and a radiometric scanner system (RMS), COSMOS 1870 has two deployable solar arrays and batteries for power supply. Its configuration is an OPS Module based on the Almaz bus, and it was manufactured in the Soviet Union. The planned lifetime of the satellite was 2.5 years, but it reached only about half of that time before operations ceased.
