Obzor

Finally, the Arsenal Design Bureau has proposed converting its military ocean reconnaissance spacecraft bus (EORSAT) into a civil remote sensing platform. Called Obzor, the newspacecraft would feature a 4-channel model of the Travers SAR with a large antenna similar to the one proposed for Almaz 2. Developed by the Moscow Energy Institute, the radar would operate at wavelengths of 5.7, 9.2, 23.5, and 65 cm and would employ new processing and interpreting techniques created by the Institute for Space Geoinformation. The size and mass of Obzor would necessitate employing a Rus launch vehicle rather than the Tsyklon-2 used by EORSAT (Reference 725).
