Abstract: The space-borne gravitational wave detectors, LISA, TAIJI, and TianQin, are scheduled to be launched in 2030s. The well-deployed detectors networks can observe GWs with significant advantages. In this talk, we will introduce the merits of joint observation by reviewing the first detections from advanced LIGO-Virgo interferometers, and then we examine potential LISA-TAIJI network to optimize the GW observation in space. By using an ephemeris framework, we revisit orbital configurations for the TAIJI mission to perform the joint observation with LISA. We will report the detectability investigation from three alternative LISA-TAIJI networks for the GW signals from massive black hole binaries and stochastic GW backgrounds.
