METEOR-M High Resolution Picture Transmission (HRPT)
Frequencies 1700 MHz
Frequency Range 1700 MHz - 1700 MHz
Mode RAW
Modulation PSK
Emission Designator
Bandwidth 3 MHz
Location Worldwide
Short Description A variant of the NOAA HRPT signal, which has a different data structure and better low-signal handling characteristics.
I/Q Raw Recording
Audio Sample

The Meteor-M series of satellites transmit high resolution pictures from the MSU-MR (main radiometer) and additionally, data from MTVZA (a microwave sounding instrument) over an HRPT link. However, while the signal is still being PSKPhase-Shift Keying modulated, the data structure is different than the NOAA HRPT signal. This gives improved low-signal handling characteristics and makes the signal incompatible with NOAA HRPT decoders.

Data transmitted[edit]

  • 6 channels from MSU-MR radiometer
  • 30 channels from MTVZA microwave sounder
  • DCP (Data Collection Platform) data
  • BIS-M (onboard information system) data
  • Spacecraft RTC (Real Time Clock)
  • Spacecraft telemetry

Data structure[edit]

The signal is transmitted as a continuous sequence of phase-shift keyed Manchester encoding at 665.4 Kbit/s rate (transport rate is 1330.8 Kbit/s). Logical "1" is represented by symbol “10” (two bits), and logical "0" - by symbol "01" (two bits).

Data is packed into frames that are sent continuously one after another without intervals using time-division multiplexing. One frame consists of 1024 bytes. The most significant bit of each octet comes first.

Signal characteristics[edit]

  • Right-hand circular polarization
  • Phase shift keying modulation
  • 3 MHzMegaHertz (MHz) 10^6 Hz bandwidth
  • Transmit power 5 watts
