摘要：

The principle of two-way satellite comparison is synchronous transmission and receipt of time signals by two stations. By eliminating the error of transmission path, it achieves a high precision. Its disadvantages are low efficiency, requiring much satellite link time and inadequacy for automatic operation. The newly developed terminal, which allows simultaneous observations of many stations, can overcome these disadvantages. For the new terminal a new method of processing is hereby presented. As shown by our research, simultaneity of observations of many stations enables the extraction of more information, contributing to the improvement of the accuracy of comparison.
