Meteor-M satellites are a new generation of Russian meteorological satellites to replace the Meteor-3M series. The first two Meteor-M satellites will feature following instruments: - MSU-MR - Low-resolution Multispectral Scanner for global and regional for cloud cover mapping - KMSS-2 - multichannel scanning unit for Earth surface monitoring - MTVZA-GYa - imager/sounder for Atmospheric temperature and humidity profiles, sea surface wind - IKFS-2 advanced IR sounder for Atmospheric temperature and humidity profiles - BRK SSPD - Data Collection System - RK-SM-MKA - Modified Rescue Radio complex One initial Meteor-M 1 satellite was built, followed by the improved Meteor-M 2 series satellites.
The 2.1a version includes conversion from analog to digital flight control system and uprated engines on the booster and the first stage with improved injection systems. The new digital flight control and telemetry systems allow the rocket to launch from a fixed rather than angled launch platform and adjust its heading in flight. A digital control system also enables the launch of larger commercial satellites with wider and longer payload fairings such as the ST-type fairing. These fairings introduce too much aerodynamic instability for the old analog system to handle.
