RS-10/11 is a Soviet amateur radio payload aboard Kosmos 1861 , a Zikada series satellite .

construction

The unusual double designation RS-10/11 comes because there were two amateur radio payloads. The payloads were built by radio amateurs and referred to as the "On-Board Radio Technology Complex BRTK-10". This used the power supply and the permanent attachment to the platform of the Zikada satellite. Usually one payload was in operation (mostly RS-10), while the second was kept as a reserve.

Both payloads had receivers in the 2 m band and in the 15 m band as well as transmitters in the 10 m band and 15 m band, which could be configured to a 40 kHz wide transponder with five different modes:

  • A - uplink 2 m band, downlink 10 m band
  • K - uplink 15 m band, downlink 10 m band
  • T - uplink 15 m band, downlink 2 m band
  • KA - uplink 2 m and 10 m band simultaneously, downlink 10 m band
  • KT - uplink 15 m band, downlink 2 m and 10 m band simultaneously

Furthermore, a robot autotransponder could be activated. The robot autotransponder could be called by telegraph, confirmed the call, assigned a connection number, called his name (Robot) and said goodbye. The downlink transmitters had a maximum output of 5 watts.

mission

The satellite was June 23, 1987 with a Soviet Cosmos-3M - carrier rocket from the Plesetsk cosmodrome launched from Russia. The satellite failed in May 1997 after 9 years and 11 months of operation.
