GRU satellites

A couple of weeks ago, I received a note that some -or maybe all- GONETS satellites are still transmitting. According to various sources, these satellites were test birds only and should be decommissioned in 1997.

GONETS are Russian LEO store-and-forward satellites, owned by the GRU. Store-and-forward systems are communications systems in which messages are received at intermediate routing points and recorded i.e., stored, and then transmitted, i.e., forwarded, to the next routing point or to the recipient.

The system should be composed of 36 satellites on 6 orbital planes.

The project was launched in 1992 but not completed because there was no funding for an improved version. Yet, at least three of them are still alive and transmitting.

The original frequencies for the GONETS birds were in the 300-400 MHz range VHF/UHF band and the 1.5-1.6 GHz band. Uplinks were from 312-315MHz and 1624.5-1643.4 MHz, and downlinks from 387-390 MHz and 1541.0-1541.9 MHz.

The satellites that have been logged during the past few weeks are:

GONETS-D1 was to be deployed in a constellation of 12 satellites (2 planes of 6) between 1996 and 1998. Each satellite had a single simultaneous earth-space and space-earth channel. On-board storage was 12 Mbits of data, with a transmission rate of 2.4 kbit/sec. You can hear short data bursts in Narrow-FM when the satellites pass.

For those of you who want to give it a shot..... here are the TLEs.
