The structural features, radio signal parameters, and electronic equipment of the MARS transportable satellite communications station are summarized, and some results of its operation in conjunction with the communications satellite Molniya-2 are discussed. Television picture signals are transmitted by frequency modulation with a peak deviation of 15 MHz. Linear and nonlinear preemphasis are introduced into the signal, producing a 2-3 dB gain in the SNR. The nominal transmitter power is 3 kW; the passband is plus or minus 17 MHz with a variation of 1 dB. The communications signals are transmitted by a frequency multiplexing method on separate carriers, combined at the intermediate frequency with the television information carrier. The station antenna has a 7 m parabolic reflector. The total noise temperature of the station is 125 K. The antenna aiming system allows the station to operate in an automatic satellite tracking mode, and in programmed tracking modes with and without automatic correction of program errors.
