The 600 MHz band started
to be sued in the 80's and is widely used on Russian spacecraft. It now
seems to be used also for upper stages that need long-range tracking stations.
The table below lists the frequencies known so far.

It is quite interesting to
note that as the VHF band has largely been abandoned for Russian satellite
telemetry (virtually only Soyuz and Progress spacecraft still use this
band) it is widely used for launch vehicle telemetry and the same precise
frequencies used by spacecraft are still in use on launch vehicles.

132.4 | Proton K,M 3rd stage | ||

This frequency band has probably
been used for missile telemetry since it is much used on the Rokot, which
is a modified missile. However, It now turns out to be widely used for
upper stages, such as the Soyuz third stage, Breeze and Ikar (a modified
Yantar reconnaissance satellite service module)
Frequency (MHz) | L/V use | S/C use |
1002 | Soyuz 3 rd stage | |
1002.5 | Soyuz ST 3 rd stage | |
1010.5 | Zenith-SL | |
1018.0 | Zenith-SL | |
1018.5 | Breeze-M | |
1020.5 | Breeze-K, -M | |
1042.5 | Breeze-K | |
1080 | Ikar |
The standard orbit and trajectory
determination system suing S-and transponders are used on launch vehicles
and spacecraft. For example, Soyuz spacecraft and the Kosmos-3M launch
vehicle carry radar transponders transmitting on 2805 MHz +/- 10 MHz and
receiving on 2725 MHz +/- 30 MHz. Probably the +/- indication is the actual
bandwidth of system..
This hitherto unknown system is listed as using a downlink at 3410 MHz for both Proton M and for Fregat. Its uplink is listed as 5754.9 MHz for Fregat and 5750-5750 for Breeze-M, the new upper stage of Proton. In the Starsem manual this tracking system is described as "designed for a range between 1000 km and 45000 km, and is switched on during flight when the Fregat reaches an altitude higher than 1000 km". The standard S-band radar transponder sytem is listed as only useful up to 8000 km range.
