该系统占用ＳＣＰＣ数字卫星通信地面站的一个话音通道，其带宽仅有４５ｋＨｚ，由１个主站和１个到６２个副站组成．所有的系统同步过程都由主站控制自动完成．该系统采用扫描原理，以对话方式实现一点对多点的时间同步．其特点是：占用频带窄，节约卫星资源；实时性强；自动化程度高；自动多点同步；相位自适应技术；时间同步精度高；功能齐全．该系统已正式投入使用，实验证明系统同步准确度优于２μｓ．
The system occupies one of the voice channels of the SCPC digital satellite communications ground station and has a bandwidth of only 45 kHz, consisting of 1 master and 1 to 62 secondary stations. All system synchronization is done automatically by the master control. The system uses the scanning principle to achieve a one-to-many time synchronization through dialogues. Its characteristics are: narrow occupancy band, saving satellite resources; real-time; high degree of automation; automatic multi-point synchronization; phase adaptive technology; high precision time synchronization; full-featured. The system has been officially put into use, experiments show that the system synchronization accuracy better than 2μs.
