It has completed 13 satellite maritime monitoring and control tasks such as the Beidou satellite series, and is carrying out the Long March 5 remote three rocket maritime transport mission. In addition, Yuanwang No. 7 is the command ship of China's first solid rocket launching technology test mission, and has successfully completed many tasks such as marine command, rocket tracking measurement and mission support.
Before the departure, Yuanwang No. 5 and Yuanwang No. 7 each carried out a series of task preparations, including material replenishment, equipment maintenance, performance index test, technical status check, etc. Practical problems such as short effective preparation time, frequent changes in technical status, and difficulty in risk management and control, highlighting targeted preparations and continuously enhancing the competency of post personnel.
