The article provides recommendations for solving the problem of determining the peak power of a pulsed optical signal. A variant of seasonal changes in the values of the integral albedo of the Earth is considered, taking into account the imposition of background noise. Experimental data obtained from the “Glonass-М” satellite correlate satisfactorily with theoretical calculations of background illumination calculated for different spectral ranges.
For spacecraft in orbit with an altitude of 19 100 km, when calculating the peak power of the useful signal? it is necessary to take
into account the values of background illumination in the ultraviolet region Wlulmax=5,3·10-4 Вt/сm2, in the infrared region
Wlinf max=14.0·10-4 Вt/сm2.
