Abstract

Abstract

In order to analyze the effect of injection error on gravitational wave detection, and keep arm length, breathing angle, arm length variation rate and distance to earth acceptable, the effect of injection error is investigated. First, the Monte-Carlo and CADET are tested and compared. CADET is proved to be correct. The effects of position and velocity error on constellations are researched with the CADET method. Experimental results indicate that the relative error between CADET and Monte-Carlo is less than 6%, and the calculated time of CADET is less than 1 min. Radial position error and tangential velocity error have a greater effect on constellation. If the position error of the three satellites are in same direction, maintaining stability is easier. The same is true for velocity error. A constellation can remain stable when position error is no more than 160 km and velocity error is no more than 3 cm/s. CADET is appropriate for injection error analysis because of its accuracy and high efficiency.
