China’s first Mars exploration mission will use a new generation of flight control system.

Reporters from the Beijing Space Flight Control Center (hereinafter referred to as Beijing Center) learned that China’s first Mars exploration mission will be fully adopted a new generation of flight control hardware and software systems. At present, the preparation of various flight control missions is progressing smoothly. Li Jian, director of the Beijing Center, said that recently the center’s researchers organized a number of reliability tests, stress tests and stability tests, completed the software third-party evaluation, and through various joint tuning exercises, a comprehensive and systematic test of the next generation of software systems and domestic hardware platform functional performance and coordination of the match, for the successful completion of the task laid a solid foundation.

China’s first Mars rover will be launched on July 17, the National Space Administration announced on July 17, to carry out a global and comprehensive orbiting exploration of Mars, and to conduct regional exploration on the surface of Mars.

The Beijing Center serves as the command and decision center, the control computing center, the data processing center, the information exchange center and the long-term aircraft management center in the Mars exploration mission. At the same time bear the earth-fire transfer orbit control, Mars surround capture control, fire remote operation control and surround machine operation management and other tasks. In order to ensure the completion of the flight control mission, the center and the mission system in close cooperation, according to the plan to promote the development of flight control program, flight control system development, mission site construction, joint test exercise and other work.

According to cui Xiaofeng, the center’s first Mars exploration mission model, the mission is relative to manned space flight and lunar exploration mission, with spacecraft platform new, new exploration field, long implementation cycle, complex measurement and control mode, high orbital control requirements and difficult emergency disposal and other characteristics of difficulties.

Beijing Center in early 2018 set up a Mars exploration mission flight control team, this year, for the First Flight of the Long March 5 B rocket, the first Mars exploration, Chang’e-5 and the space station and other major space missions in parallel preparation of the situation, the center actively overcome the impact of the epidemic, overall adjustment of personnel strength, closely organize the test site overall allocation and scientific deployment of measurement and control network resources, in accordance with the “relatively independent, time-sharing re-use” principle, developed a site use and system switching program; The requirements for the deep space measurement and control station were carried out in parallel by the Mission No. 5 and the Relay Star and the Probe Long Tube Mission, and the resource allocation strategy of the measurement and control network was formulated to ensure that the mission needs were met.

It is reported that in October 2019 and February to March 2020, Beijing Center has completed the in-field remote operation joint test and wireless joint test, the center program design, inter-system interface and a new generation of flight control system verification. In June 2020, they organized the completion of the deep space interface joint test and measurement and control communication system, the task of the correctness of all kinds of information sent and received to confirm. Recently, they focused on the key flight control process collaborative exercise, the task system and inter-system work collaboration to verify.
