The Meteor M2 LRPT Weather Satellite has Failed
Meteor M2 is a Russian meteorological satellite whose LRPT transmissions at 137 MHz were relatively easily received by anyone with a simple satellite antenna and an RTL-SDR and computer. Meteor M2 was launched in July 2014, and it should not be confused with Meteor M2-1 which failed on launch in 2017 due to an upper stage deployment issue, or Meteor M2-2 which suffered a micrometeorite strike in 2019.
Unfortunately it appears that Meteor M2 has permanently failed on 24 December 2022. Problems with the Meteor M2 satellite losing orientation stability have occurred several times in the past, and have always been fixed within a few days after the event. There was initially hope that after the holidays when the engineers returned to work that the problem would be fixed. However @Serge, a Russian radio amateur who talks with Meteor engineers on Russian amateur radio forums has recently mentioned on Twitter that recovery seems unlikely.
As well as @Serge's twitter, Happysat keeps track of Meteor M2 satellites on his Meteor M2 status page so keep an eye there for any updates. At the moment all LRPT transmissions have been turned off.
In 2019 the Meteor M2-2 (the third M2 satellite) also failed in December due to a micrometeorite strike. Meteor M N2-2 was partially recovered, and while it can no longer transmit LRPT, it can still transmit HRPT in the L-band, when in sunlight.
The good news is that Meteor M2-3 is due to be launched in 2023, and this will hopefully bring back LRPT reception. Currently the only weather image satellites transmitting at 137 MHz are NOAA-15, NOAA-18 and NOAA-19. NOAA-15 still lives, but may be slowly failing. NOAA-18 and NOAA-19 are also aging satellites but show no signs of wear so far.
If you are interested in satellite reception and want to future proof your setup against more 137 MHz band satellite failures, we recommend looking in LRIT/HRIT or HRPT satellite reception which is a little more complex, but has become significantly easier to get started with in recent times.
Meteor-M2 is apparently completely lost for LRPT.
Only devices that do not require precise orientation are enabled to work.
Data/Information is only received when a ground station accidentally hears Meteor-M2 sporadically.
We hope to see you again on Meteor M-N2-3!
