METEOR-M N2M

Meteor-M N2 is a Russian polar orbiting weather satellite launched on July 8, 2014.

Its main missions are weather forecasting, climate change monitoring and sea monitoring.

Meteor-M N2 transmits a Low Resolution Picture Transmission (LRPT) signal which broadcasts live weather satellite images, similar to the APT images produced by the NOAA satellites. LRPT images are broadcast as a digital signal with an image resolution 12 times greater than analog NOAA APT signals.
