High Precision Space Inertial Reference Construction Technology

Facing the requirement of space gravitational wave detection mission, this paper analyzes the method and key technology of high precision inertial reference construction, and introduces the on-orbit verification of the test satellite. Firstly analyze the requirement index and technical approach of inertial reference construction, the noises which affecting the construction of inertial reference are classified and introduced according to the sources; Then, for all kinds of noise it analyze the corresponding key technologies which spacecraft platform to be solved; Finally, combined with the design and on-orbit test of tianqin-1 satellite, the current status and gap of various key technologies are analyzed. On-orbit test result show that, some technical indicators are close to meeting requirement which the space gravitational wave detection mission needed.
