Monitoring the energy characteristics of multispectral scanners on board the Resurs-01 satellite
Abstract
A procedure and instruments for monitoring the characteristics of the multispectral scanners MSU-E and MSU-SK onboard the Resurs-01 satellite are described. Monitoring accuracy estimates are given for preflight and flight states of tests. MSU-E and MSU-SK parameter stability during operaton on board the Resurs-01 is discussed. For the case of signal values, good agreement was observed between rated and experimental data with the exception of an MSU-E survey in December 1989. It is suggested that the lower measured magnitudes are due to the insufficient cloud thickness and the influence of the darker underlying surface. The wide range of possible values of effective cloud brightness leads to an MSU monitoring error of up to 30 percent. Comparison of experimental and rated values shows that, within a range of 10 percent, the correlation between signals measured in orbit corresponds to the preflight data.
