Russian Space Forces Launch Navsat - Update

The Russian Space Forces launched a Parus military navigation on 11 Sep 2007 at 1305 UTC from Plesetsk Space Complex (LC132 Pad 1).

Name: Cosmos 2429
International Designator: 2007-038A
SSC #: 32052
Mission: Military Navsat - Parus type
Launch Date/Time: 11 Sep 2007/1305 UTC
Launcher: SL-08/C-1, Kosmos-3M
Orbital Period: 104.63 minutes
Orbital Inclination: 82.98 degress
Apogee: 999 kM
Perigee: 956 kM
Eccentricty: 0.0029585
Downlinks: 150.030 MHz (FM FSK) and 400.080 MHz

The Tsyklon series was followed by the fully operational "Tsyklon-B" or "Parus" system. Unlike the wildly varying Transit satellites, the Tsyklon and Parus satellites had similar configurations. Both are in the form of a drum covered with solar cells, with a weighted mast on top for gravity-gradient stabilization, and a what appears to have been an antenna hung off one side near the bottom. They are all launched from the Plesetsk Northern Cosmodrome by the standard Soviet Kosmos 3M medium-lift booster, one satellite per shot, though a few did include small secondary payloads. The developed Parus satellites had a launch weight of about 810 kilograms (1,785 pounds), and were placed into a near-circular orbit of about 1,000 kilometers (620 miles) at a near-polar inclination of 83 degrees.

Russian Military Navsat Status Report



In the October 2006 issue of my Monitoring Times Milcom magazine column, I covered a lot of the easy satellites there are to hear in the radio spectrum. One of those is the Russian "Cosmos" military navsats that transmit in the 150 and 400 MHz portions of the spectrum. You can get a reprint of that article from the folks at Monitoring Times. It will also be available soon on CD-ROM on the 2006 MT Anthology.

In the article I covered modulation and decoding information on these military navsats.

But as an exclusive for my blog readers, here is my latest Russian Navsat constellation status report based on monitoring from my Btown Monitoring Post:
