Abstract:

With the continuous progress of aerospace technology, the role of the space Telemetry, Operation, Command and Control (TOCC) system is increasingly critical, and therefore, improving its performance is of great significance for addressing the high-density and diverse demands of future space missions. Comparative analyses of TOCC system architectures and operational models between domestic and international frameworks are provided. This paper analyzes the research progress and development opportunities of these key technologies, presenting a detailed analysis across four domains of TOCC system. The development trajectory of these systems is further clarified in terms of autonomy, efficiency, and coverage, proposing an integrated construction approach with standardization, intensification, and intelligence. This paper introduces the concept of an integrated TOCC system, systematically identifying full-link technical challenges and developments tailored to the future space development.

Key words: Telemetry, Operation, Command, Control (TOCC) system, space TT&C network, satellite operation, command decision, executive control
