While the American segment of the ISS has data published on-line (http://spacestationlive.nasa.gov), the same cannot be said about the Russian segment.

It is known that telemetry is transmitted to the Earth on 128 kHz-wide PCM (Pulse-code modulated) FM (Frequency modulated) channels at 628, 630, 632, 634, 922, 928 MHz (source: http://www.ea1uro.com/megasat.html).

  • How could one receive, demodulate, and decode the telemetry?

  • Is Russian ISS telemetry encrypted?

  • Are there any high-frequency data items in the frames (transmitted more often than once a second - 1 Hz).

Historical reference: Sven Grahn's Space Radio page.

  • $\begingroup$ When you'll get your hands on the data, double check what you have really got. There's an anecdote about a fake telemetry provided to ESA. The data kept coming even after the station has been deorbited. translate.google.com/… $\endgroup$

  • $\begingroup$ The russian segment uses Regul-OS as a command system, BITS2-12, and BR-9TsU-3 as telemetry systems. In general, the answer should be fleshed out much more. $\endgroup$ Aug 31, 2013 at 22:34
