According to the space instrumentation system and data processing technology, this paper probes the technical measures for improving the tracking system of S-band space TT&C network of our country, presents several improving measurements for the instrumentation system, and analyzes the superiority of related observation equations.

With the rapid increase of number and types of Chinas S-band spacecraft and the realization of the thru-put telecommand mode of the Ground-based S-band TT&C (Tracking, Telemetry and Control) Network(GSTN), new requirements are needed for the mission control center and the ground TT&C stations(GTS).

Researches on the Constitution and Performance of Management System for Space TT&C Network Based on the B-ISDN/ATM;

With the development of Internet, Spaceflight TT&C Network accessing Internet is an effective way to enlarge the coverage.

On the basis of multiple satellites task requirement analysis, the paper creates the scheduling model of Spaceflight TT&C network resource allocation, and gives the related model solution arithmetic.

Quantum key distribution in the distributed TT&C network

On the space TT&C (telemetry, tracking and command) network is researched.

The improvement and application of network time protocol in the new space TT&C network;
