| Summary: | Technology of prelaunch geometric calibration of multispectral imagery instruments of Russian geostationary satellites “Elektro-L”
No.1 and No.2 is considered. Circular control points are used as a test field. Its geometrical model is developed to take distortions in
the collimator optical system into account. Multiple observations of a test field at different angles is used to cover the full visual field
of a geostationary sensor. New algorithm of circular control point detection is developed and adapted to complex geometry of
geostationary imagery. It is capable of processing images formed as a set of separate scans. Under calibration, sensor design
parameters and also the law of scanning mirror motion are specified. The paper contains results of the technology approval under
prelaunch calibration of MSU-GS sensors for geostationary operational meteorological satellites (GOMS) “Elektro-L” No.1 and
No.2. |
