摘　　要：The space-based laser interferometers,LISA,Taiji and TianQin,are targeting to observe milliHz gravitational waves(GWs)in the 2030s.The joint observations from multiple space-based detectors yield significant advantages.In this work,we recap the studies and investigations for the joint space-based GW detector networks to highlight:1)the high precision of sky localization for the massive binary black hole(BBH)coalescences and the GW sirens in the cosmological implication,2)the effectiveness to test the parity violation in the stochastic GW background observations,3)the efficiency of subtracting galactic foreground,4)the improvement in stellar-mass BBH observations.We inspect alternative networks by trading off massive BBH observations and stochastic GW background observation.
