PLEASE NOTE: Both LRPT receiver/decoder applications here (glrpt and mlrpt) will no longer be maintained by me, unless a bug is reported or discovered. Viktor Drobot, a Russian developer, has taken over the development and upgrading of these applications and he is also developing liblrpt, an LRPT demodulation/image decoding library for general use. Unless you have some reason to use glrpt and mlrpt as available here, then please visit Viktor's github page to follow development and download LRPT applications from there.
glrpt:
glrpt is an interactive X/GTK+-3 GUI integrated application for Receiving, Decoding and Displaying LRPT Images from the Russian Meteor-M type of Weather Satellites. glrpt supports reception through the now very popular RTL-SDR receiver dongles, available cheaply from many sources. By user request, glrpt now uses the SoapySDR library and has been tested with the Airspy Min and R2 SDR receivers as well. Other units supported by SoapySDR may be usable. glrpt is released under the GPL v3 OSS license.

mlrpt:
mlrpt is non-interactive and non-graphical version of glrpt, intended for use from the command line or from scripts. mlrpt supports reception of LRPT images through the now very popular RTL-SDR receiver dongles, available cheaply from many sources. mlrpt now also supports the Airspy R2 and Mini SDR receivers.

met_decoder:
met_decoder is a translation to C of Artem Litvinovich's Pascal program "meteor_decoder". met_decoder works in almost the same way as meteor_decoder and produces the same images, decoded from a file of raw or soft recordings of symbols, as transmitted by the LRPT channel of the Russian Meteor-M weather satellites. met_decoder has some additional code of my own that can perform histogram normalization (contrast stretching) of the images and further pseudo-coloration of the compound image. Both these functions can be controlled by some additional command line options. Please read the README file in the source directory for more details. met_decoder is released under the GPL v3 OSS license.

met_demodulate:
met_demodulate is a demodulator for the LRPT QPSK symbol transmission system of the Russian Meteor-M weather satellites. With the help and co-operation of the upstream developer, dbdexter-dev, some bugs reported by Coverity Scan or noticed by me have been fixed and the original source code repackaged here to compile in a GNU Autotools environment. met_demodulate produces a file of soft QPSK symbols which can be decoded by met_decoder to produce images. Please read the README file in the source directory for more details. met_demodulate is released under the GPL v3 OSS license.

rectify-jpg:
rectify_jpg is a command-line tool that rectifies (corrects geometric distortion) of Meteor-M weather images. This distortion is caused by the scanner's geometry as well as the curvature of earth and it results in a progressive compression of image lines towards the edges. This package was kindly provided by Rich Griffiths W2RG and will be incorporated in glrpt and later mlrpt.
