Abstract

This work firstly introduces the requirement， principle and development of inertial sensors in gravitational wave detection mission， and focuses on the development of LISA Pathfinder inertial sensors. Compared with the requirements analysis of TianQin project， the design points of TianQin inertial sensor are discussed， and on this basis， the preliminary design and noise analysis of TianQin inertial sensor are given.A preliminary design of the key parameters for the TianQin inertial sensor is then carried out， which are employed to calculate and synthesize the direct perturbations on TM. Finally， the in-orbit performance of TianQin-1 inertial sensors and follow-up research plan is presented.
