Abstract :
This paper addresses the problem of increasing the speed of information transmission by radio downlink channel in remote sensing based on low-orbit spacecrafts (SC). It is shown that for X-band standard capacity may be increased by an order. Possibility of using the Ka-band is considered for high speed radio downlink design. An estimation of power budget for X- and Ka-band downlinks carried out.
