Abstract

Abstract

Detecting gravitational waves on ground was limited by the noises such as surface vibration, gravity gradient and the test scale. The detection frequency band is limited to more than 10 Hz while the detection frequency band is mainly in the middle and low frequency band(0.1 mHz~1 Hz) for wave sources with larger feature quality and scale. So in order to avoid ground interference, detection from space is inevitably necessary. As gravitational wave signals are extremely weak and their required detection accuracy is extremely high, space gravitational wave detection projects represented by LISA was proposed by ESA and Taiji was proposed by the Chinese Academy of Sciences. However, both domestic and foreign proposed projects had extremely high requirements for satellite technical indicators, design complexity and cost. They were hard to achieve in the short term. This paper refers to the design of LISA pathfinder, designs a near-field low-cost commercial satellite for the verification requirements of gravitational wave detection key technologies, analyzes the satellite mission design and proposes ways to verify its structure, thermal and attitude control technologies. In this paper, a preliminary idea of commercial low-cost technology verification was proposed to provide reference for the design of space gravitational wave detection satellites.
