Space-based gravitational wave detectors such as TianQin, LISA, and TaiJi have the potential to outperform themselves through joint observation. To achieve this, it is desirable practice data analysis in advance on simulated that encodes intrinsic correlation among signals found different operate simultaneously. In this paper, we introduce \texttt{GWSpace}, a package can simulate detection from TaiJi. The software not groundbreaking work starts scratch. Rather, use many open-source resources possible, tailoring them needs of simulating multi-mission science putting everything into ready-to-go easy-to-use package. We shall describe main components, construction, few examples application A common coordinate system, namely Solar System Barycenter (SSB) utilized calculate spacecraft orbits for all three missions. paper also provides brief derivation process outlines general waveform sources detectable by these detectors.
