Introduction
The low-rate picture transmission (LRPT) is a digital transmission system, intended to deliver images and data from an orbital weather satellite directly to end users via a VHF radio signal.
NOTE: The LRPT demodulator which has been previously used on some SatNOGS stations is an custom addition, and is not part of the core SatNOGS demodulator set. It also has not been updated to work on the latest SatNOGS versions (newer than ~Feb 2020).
