Zenit-2M (Gektor, 11F690)

Zenit-2M / Gektor

The soviet Zenit-2M (Gektor, 11F690) was an improved version of the Zenit-2 area surveillance reconnaissance satellite. It was part of the Vostok-based Zenit-family.

The satellites consisted of the Vostok-based service and reentry modules. The spherical reentry module returned both the cameras and the film to earth at the end of the mission. This version replaced the Ftor-2R camera system with the improved Ftor-2R3 camera. The battery powered spacecrafts were designed for flights durations of 12 to 13 days.

These satellites operated from following, typical orbits:

  • 65.0, 204-288 km altitude
  • 62.8, 200-294 km altitude
  • 51.8, 202-256 km altitude
  • 71.3, 205-316 km altitude
  • 72.8, 203-312 km altitude
  • 81.3, 210-232 km altitude

The Zenit-2M satellites could carry autonomous scientific and technical Nauka payloads and deploy other payloads from the front end of the spherical return capsule. Kosmos 368 carried also biological experiments as a precursor to the dedicated Bion series.

A civil earth resources version was launched as Zenit-2M/NKh (Gektor-Priroda). The Zenit-2M was later replaced by the Zenit-6U (Argon) version.
