Kun-Long Wu and Jia-Yun Qi from JLPP went to Shandong Institute of Aerospace Electronics Technology, a subsidiary of China Aerospace Science and Technology Corporation (CASC), to conduct the ion-liquid thruster power supply performance test. The test process was conducted in the assembly hall of the Micro-Nano Star Division of Shandong Institute of Aerospace Electronics Technology. The test content includes electric propulsion module power-on work, interface adaptation, communication status, etc. The communication test included the signal extraction of the electric propulsion module working status by the on-board computer and the regulation command of the thruster positive and negative polarity working status. The test process lasted about 3 hours, the thruster power supply performance is stable, the transmission value is accurate, the transmission signal is stable, and finally completed the test task successfully. The parties exchanged views on common concerns such as thruster operating status, operating characteristics, operating mode, requirements of micro-nano satellites for thrusters, and thruster testing technology.

After this trip, we will optimize the electric propulsion module for the potential problems and pitfalls exposed during the testing process, and put the prototype into production and leave the factory as soon as possible to ensure that the development of the electric propulsion module will complete the performance and environmental testing within the expected target time, and fully cooperate with the overall joint tuning of Beihang SSS-1 satellite. Thank you for the support of Mr. Huang Hai’s team and Zhang Zongzheng’s team from Shandong Institute of Aerospace Electronics Technology, who provided assistance during the testing process.
