Fragmentation Technology of Spacecraft TT&C Resources Under Multi-constraint Condition

With the development of the world space industry, the number of spacecrafts in the future will increase much faster than the ground-based TT&C equipment and space-based TT&C capacity. In the case of SpaceX's Starlink Constellation program, all 4409 satellites are expected to function by 2024, eventually forming a supergiant Internet constellation of about 42,000 satellites. Therefore, with the rapid improvement of spacecraft technology and quantity, there is an urgent demand for space TT&C capability. How to speed up the reasonable allocation of TT&C resources, make efficient use of existing TT&C resources, and delve the potential of TT&C resources deployment is a practical and innovative mission. Based on China’s many years of space TT&C practice and the practical problems in ground-based space TT&C capability, this paper puts forward a fragmentation of TT&C resources reorganization algorithm (FRRA) under multi-constraint conditions and studies the technology of deep excavation of the ground TT&C capability of spacecraft. The results of this paper are of practical engineering significance to the existing mode and utilization efficiency of space TT&C in China.
