An APT transmission was planned to only have a reduced resolution (2 km) visible channel data.
Secondary mission objective was the flight testing of the novel-type spherical retroreflector for precise laser ranging.
The retro-reflector was a glass ball 60 mm in diameter, fastened in a holder providing observation from Earth at elevations of more than 30° (the retroreflector field of view was centered in the Nadir direction).
Meteor-3M No.1 included the SAGE III (Stratospheric Aerosol and Gas Experiment) payload and other instruments designed to measure temperature and humidity profiles, clouds, surface properties, and high energy particles in the upper atmosphere.
SAGE III was a gyrating spectrometer that measured ultraviolet/visible light, which was used to enhance understanding of natural and human-derived atmospheric processes by providing accurate long-term measurements of the vertical structure of aerosols, ozone, water vapor, and other important trace gases in the upper troposphere and stratosphere.
