The spaceborne gravitational wave (GW) detectors LISA and TAIJI are planned to be launched in the 2030s. The dual detectors with comparable sensitivities will form a network observing GWs with significant advantages. In this work, we investigate the three possible LISA-TAIJI networks for the different location and orientation compositions of the LISA orbit (+60° inclination and trailing the Earth by 20°) and alternative TAIJI orbit configurations, including TAIJIp (+60° inclination and leading the Earth by 20°), TAIJIc (+60° inclination and colocated with LISA), and TAIJIm (-60° inclination and leading the Earth by 20°). Of the three LISA-TAIJI configurations, the LISA-TAIJIm network shows the best performance in the sky localization and polarization determination for massive binary systems due to its better complementary antenna pattern, and LISA-TAIJIc could achieve the best cross-correlation and observe the stochastic GW background with optimal sensitivity.
