Abstract
The principle of digital satellite TV differential timing is illustrated and the error sources that influence timing accuracy are analyzed, which include ephemeris error and error caused by ranging method and signal transmission. Error correction and estimation are also presented. By comparing with Two Way Satellite Time Frequency Transfer method, the results after error correction and data processing show that the timing precision of digital satellite TV differential timing method is higher than 10ns.
