This paper presents an evaluation of Doppler Shift and Doppler Rate for the communication HEO satellites. A method for Doppler shift compensation is consideredwhich allows increasing channel capacity.

A lag of CCSDS recommendation is shown. Main part of onboard equipment-Tracking, Telemetry and Command Subsystem is shown as source for potential improvements for new standards. It is possible by increasing of estimation accuracy of the parameters of the orbit of spacecraft.
