22 Mar 2022: Russia launched the Meridian-M No 10L satellite onboard a Soyuz 2.1a from the Russian Plesetsk Cosmodrome. This was first space launch for Russia’s military since forces invaded Ukraine last month. Launch Video.

– Meridian 10 joins 3 other currently active Meridian satellites (7/8/9). The satellite is in a very highly elliptical Molniya orbit of 900 x 39,000km, with an inclination of 65°.

– While the Meridian-M network does provide support for the Russian military, the timing of this launch is not related to the current war in Ukraine. The deployment of the Meridian-M constellation has been underway since 2019, and the overall Meridian network since 2006.

– The satellite is part of the upgraded constellation’s M-series. One more upgraded M-series satellite is planned for later this year.

Due to their elliptical orbits, Meridian satellites link Russian ground forces, aircraft, ships, and command centers in the Arctic, Siberia and North Sea – outside the reach of stable communications coverage unattainable from geostationary satellites over the equator.

– The Russian Defense Ministry said the satellites relay signals between coastal stations and vessels and ice reconnaissance airplanes traveling along the Northern Sea Route in the Arctic Ocean. The Meridian satellites also serve users in northern Siberia and Russia’s Far East.

– Meridian- M No 10 is the third upgraded Meridian M-class spacecraft in orbit. The first of the new batch of Meridian M satellites launched in Jul 2019, followed by another in Feb 2020.
