The frequency errors dominated by the dynamic Doppler is analyzed for mobile satellite communication systems employing fast-moving satellites. Methods are proposed and analyzed for the basestations to measure and compensate the dynamic Doppler of large range. It is shown that the proposed methods give the minimum uncertainty of the dynamic Doppler for the modem to handle. Therefore, these methods are optimal for frequency synchronization and Doppler measurement in mobile satellite communications systems
