METEOR M Demodulator SDR# Plugin and LRPT-Decoder Updated

Thanks to Happysat for providing info on updates to these programs again. Meteor Demodulator V2.2 is a plugin for SDR# that connects to the M2 LRPT Decoder software. Together with an RTL-SDR and 137 MHz satellite antenna, these programs are used to receive, track, demodulate and decode Meteor M satellite signals into live weather satellite images. Happysat has a tutorial available here, however we note that at the time of this post it hasn't been updated to use the latest software versions.

The biggest change appears that you can now affect the decoder settings from within the SDR# plugin. This is useful because the METEOR M2-2 satellite appears to be changing it's operating mode often (number of infrared vs visible channels, data rate etc).

We also note news from Happysat that the Meteor M-N2-2 satellite has now changed frequency to 137.100 MHz mode 72K on 16 Aug. 9:30 Moscow time (6:30 UTC). Other users have also indicated that M2-2 is currently transmitting two IR channels, and one visible now. Meteor M2 appears to still be transmitting visible channels.

M2 LRPT Decoder V47:

- Added Meteor Demodulator V2.2 socket support

- only mode, sat, rgb are supported so far.

- Fix manual s-file processing

By design, the plug-in will manage the settings of the decoder and this should reduce the number of settings that must be done when changing the Meteor operating modes.

Example scheduler options:

M2_decoder_init_Line <rgb=123.jpg> or (rgb=125,444,555 ect)

In order for the decoder to work with Meteor Demodulator V2.2 http://happysat.nl/meteor_2.2.zip , the ini-file mode and sat entries must be assigned to auto!

M2_LRPT_Decoder.ini

mode=auto

sat=auto

M2 LRPT Decoder V48:

- Remove debug window

Meteor Demodulator V2.2

From TSSDR:

Added interaction with Meteor LRPT-Decoder via socket.

At the beginning of the data transmission, the configuration of the modulation speed and modulation type (satellite name) is transmitted to the decoder.

That is, there is no need to change the decoder settings when changing 72K / 80K and M2 / M2.2.

It will receive signal information from the plugin.

It is enough to change the speed in the scheduler.

A new scheduler command "M2_decoder_init_Line <>" has been added to the plugin.

Using it, you can transfer any commands that are in the ini file of the decoder (for example, the command to select channels to save a color picture:

M2_decoder_init_Line <rgb = 123.jpg>)

In general, this allows you to change the settings when changing the reception conditions only in the scheduler and not in the entire chain of programs for processing the signal from the satellite.

M2 decoder compatible with these functions is >V47

Updated Meteor M-N2-2 Tutorial and Decoder Now Available

Thank you to Happysat for submitting the following information about the updated LRPT decoder for Meteor M-N2-2. He has also provided a link to his very useful Meteor Satellite reception tutorial.

Today the official LRPT-Decoder V42 ready for release :)

Before we did use a older internal debug version from 2014, because this one was still in development.

This version 42 of LRPTDecoder will work with both Meteor M-N2 and Meteor M-N2-2.

Example ini configuration files for other modes are attached in the archive.

Meteor M N2-2 Successfully Launched: Awaiting LRPT Signal

On July 5 the Russian Meteor M N2-2 weather satellite was successfully launched into orbit and appears to be healthy. The LRPT weather camera signal is not yet broadcasting however, and we expect it to still take roughly 1-2 months before it begins (if all goes well) as satellites typically run through a long list of qualification tests before becoming operational. During this time there may be broadcasts of test patterns that can be caught. Meteor M N2-2 can currently be tracked in Orbitron and online at N2YO.

To try and dispel any confusion over the naming scheme, "Meteor M N2" is the currently operational LRPT satellite. "Meteor M N2-1" unfortunately failed in 2017 as it did not separate from the rocket. "Meteor M N2-2" is the new satellite which has just been successfully launched. Meteor M N2 and M N2-2 is often abbreviated as just "Meteor M2" and "Meteor M2-2". In the past there was Meteor M N1, but this satellite is no longer operational. We have upcoming launches for Meteor M2-3, M2-4, MP-1 and M3 to look forward to which are scheduled for 2020 and 2021.

Back on June 28 we posted about how Meteor M2 was experiencing orientation issues for a few days. Those issues appear to have been rectified now. Hopefully if M2 remains stable we'll have two Meteor LRPT weather satellites to receive alongside the three NOAA APT satellites.

If you're interested, there were also several other payloads onboard the rocket carrying M2-2, including a low cost Czech experimental cubesat called Lucky7 whose telemetry can be received in the amateur radio band at 437.525 MHz. There is an onboard camera too, but no details on how to receive it yet.
