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.

    Hi all ,, spent the weekend trying to receive and decode the new Meteor satellite, had a good signal and received a nice pass .. so I though but could not decode it.
    Then I found out by chance that a newer version of the LRPT Offline Decoder was required, as soon as I had that all the images I had previously recorded decoded nicely.
    The snow on the Southern Alps here in New Zealand stands our amazingly well especially as the satellite pass was well illuminated at the 3:00pm pass time today.
    See the link on my facebook page below to take a look:

    the meteor plugin for sdr# keeps crashing for me with .net framework 4.7.2. On another pc with 4.6 it works fine.

    Hello all,

    This version of LRPTDecoder was used to test/debug OQPSK with Meteor M-N2-1 in 2014, it will work on Meteor M-N2-2.
    The ini file attached in the archive is processed manually from s files.
    Buttons 72K and 80K respectively for the modes “without interleaving” and “with interleaving”.
    Also in the archive there are examples for other modes.

    Transmissions on LRPT with a OQPSK Modulation are expected tomorrow on most probably 137.900MHz.

    Make sure you have version 1.9 of the Meteor QPSK Plugin running in SDRSharp.

    Changelog:
    Optimized QPSK demodulator, OQPSK signal for receiving current and future Meteor.

    For people running Tracking DDE Client Plugin make sure you have the following entries in the scheduler:

    Can you show by video or write chronologically how to enter this new Satellite into SDRuno etc. SDR#, MeteorGis and any other software. I have SDRplay’s RSP1a and SDR# with a dongle for meteor. This is a new hobby for me especially with the amateur bands being as bad as they are.

    um if I didnt know dit…I’d have to say that picture is an “artists visualization” and not an actual photo of the launch…
