space tracking network

Developing satellite tracking telemetry& command ( TTC) and orbit determination technology based on space-based TTC network is an effective means which overcomes limitations of traditional ground TTC mode, but utilizing satellite-to-satellite measurement would arise deficient-rank.

发展基于天基测控网的卫星测控定轨技术是克服传统地面测控方式缺陷的有效手段，而仅仅利用天基星间测量信息进行自主定轨易产生亏秩现象。

The central management and unified allocation mode applied to the space TT C(( telemetry), tracking and command) network, as well as the scheduling algorithms to meet multi-satellite TT C missions are analyzed in the paper.

研究了航天测控网资源集中管理、统一分配的工作模式，以及满足多星测控任务的测控网资源调度方法。

The deep-space exploration plan, its implementation and TT C technologies in Japan are reviewed with emphasis on the composition of Japan's ISAS deep-space TT C network, the equipment of ground tracking and control facilities, the TT C technologies and developing level.
