In order to solve the contradiction between the lack of passive 3-D navigation resource controlled by our country and the urgent need for the system,in these years,the rubidium clock method,pseudolite method and Loran-C method are developed as augmentation schemes based on Double-Star.

The principle of delay measurement applied to software Cs Sync 1000 Loran C receiver system is discussed, one delay test method for the receiver itself and two methods for the receiver system including antenna and cable are presented, the detail test procedure and the results are given in this paper , too.

The development of Loran C system is system combination with satellite,and it is complementarity and standby each other,the best performance of navigation system of own cortrol is provided.

The TOC message can be broadcasted, solely or alternating with DGNSS message, over one Loran C channel.
