ISS DOWNLINK FREQUENCY SOFTWARE

TLM downlink on 145.965 MHz, voice and image downlink on 10480. TLM downlink on 145.995, voice and image downlink on 10455.00 MHz 1 Mbps GMSK Image Transmission 10460.000 MHzĪlso SSTV, Crew Voice, and Packet Frequencies Transmits 9k6 BPSK telemetry by default, can be commanded to operate as FM repeaters.Īlso includes 3 linear transponders. When it is overhead, it is something like 215 miles overhead. When it is about 45 degrees above the horizon, the distance drops to a little less than 300 miles away. See for schedule updates.Ĭurrently active for four minutes on ascending and descending passes over mid-latitudes of the Northern HemisphereĪlso includes 2 linear transponders. At an elevation of 20 degress, the distance (or 'range') of the ISS is about 510 miles away. FM transponder operations are by schedule only. Satellite is in a low-inclination low earth orbit and not visible north of about 30 degrees north or south of 30 degrees south. The downlink frequency for this contact is 145.800 MHZ and may be heard by listeners that are within the ISS-footprint that also encompasses the relay ground station. For real time updates about which mode the satellite is in, see the AMSAT Live OSCAR Satellite Status Page The FM transponder is on no set schedule. When FM transponder is not on, there is a telemetry beacon on 437.200 MHz ( LilacSat-2 Home Page). See for schedule. For more details, see The Amateur Radio Unit can operate either as an FM transponder or APRS digipeater. Transmit a 2 second carrier with a CTCSS tone of 74.4 Hz to arm the timer.įM transponder activated by schedule. SO-50 also has a 10 minute timer that must be armed before use. Sporadically active – Due not attempt to access if heard in eclipse Operational – Due to battery status, please do not attempt to access while in eclipse.

This lets the packet downlink from ISS operate with the other APRS satellites there and.

Tools for Spacecraft and Communication Design The ISS keeps the ISS Packet station on 145.825 when it is available.

This Doppler shift will cause the ISS transmit frequency of 145.800 MHz to look as if it is 3. This high speed makes radio signals appear to shift in frequency, a phenomenon called Doppler Shift.
