英文摘要The "Taiji program in space" for space-based gravitational wave detection will open a window for observing gravitational waves in the mid-to-low-frequency range (0.1 mHz to 1 Hz). Taiji-1 satellite as the inaugural satellite, was launched on 31 August 2019, to validate several critical technologies. The radiofrequency ion micro-propulsion (RMP) as a primary propulsion system underwent in-orbit flight validation. All four thrusters successfully completed crucial performance tests. This paper will present the primary inorbit test results. It is found that the thrust range of the RMP is 5 mu N to 52 mu N. When a thrust of 50 mu N, the thrust noise is approximately 0.4 mu N/pHz (10 mHz-1 Hz), which is 2 to 4 times that of low-thrust (5 mu N). The thrust response time is about 20 ms. The characterization of RMP in orbit has reached the expectations of Taiji-1 satellite mission. The current in-orbit performance (thrust resolution, thrust noise and lifetime) of the RMP falls short of the goals set by the "Taiji program in space" and requires further enhancement.
