LRPT (Low Rate Picture Transmission) is the image downlink the Russian
Meteor-M weather satellites broadcast around 137 MHz.
How it works
- Antenna: a hand-made V-dipole cut for the 137 MHz
band, about 54 cm per side.
- SDR: an RTL-SDR records the pass.
- Decoding: the QPSK signal is demodulated and the LRPT
frames are turned into the image.
The RTL-SDR with my bad looking home-made V-dipole antenna.
I decode the captures with
SatDump.
