Onboard clock correction for SS/TDMA and baseband processing satellites
Abstract
A clock correction scheme is presented that employs a predictor to achieve stability. A linear discrete model is used to analyze the worst-case timing error, clock correction rate, and buffer size requirements for traffic stations. The effects of secondary factors such as Doppler shift, range measurement error, quantization error of correction data, and delay incurred in transferring correction data to the satellite are also discussed. Special consideration is given to a sidereal day clock correction.
