1. IntroductionThe space gravitational wave [1,2] antenna program Taiji consists of three spacecrafts flying in a heliocentric [3], with separations of L=3×109 m [4]. Each spacecraft (SC) contains two proof masses that are shielded from external disturbances. Bidirectional laser links are maintained between all SC in the constellation for exchanging laser beams to interferometrically measure the pathlength variations at the picometer level caused by gravitational waves [5,6].
