Most probably due the older vessels and submarines are still using Shkhuna Radio systems. Why the Parus-Satellites are currently still broadcasting data is unknown. They are discontinued now as the GLONASS Navigation systems did take over the service which are providing a better accurate GPS position. There are three currently operational, Cosmos 2407, 2414, and the last one launched in this series (April 2012) Cosmos 2463 with a lifespan of 4 years. The Russian Military Parus satellites are/where used for low-earth orbiting navigation information and store-dump radio communications relay service for Red Navy surface vessels and submarines.Įach satellite is in a near-circular orbit of about 1000 km (620 miles).The orbits are polar (pass over the poles of the earth) and stay stationary in space so that as the earth rotates, the satellite covers different parts of the planet. Russian Parus (Cosmos) Satellite Decoded Data With an RTL-SDR, SDR# and decoder software, Happysat was able to decode data from the satellite which includes the current Moscow time and various location and telemetry data. Since 1974 there have been 99 Parus satellites launched, but there are only three currently active.

These are low earth orbit satellites operated by the Russian Space Forces that are used for military communication and navigation. Happysat has recently been using a RTL-SDR to decode the discontinued Russian Parus (Cosmos) Navigation Satellites. Once again Happysat, who previously wrote in to to let us know how to receive dead satellites with the RTL-SDR has again written in to let us know about his latest achievements.
