AbstractTAIJI-1 is a micro-gravity experiment spacecraft. The mission target is to verify some key techniques of the spacecraft payloads for the gravitational wave detection, which involve laser interferometer, gravity reference sensor, drag-free control technology, micro-propulsion system, super-quiescent spacecraft platform, etc. The verification of the data processing pipeline required by the next stage of TAIJI Program is also performed. In order to benefit from the joint observatory between TAIJI and LISA in the future, as a space mission, the science operations refer to the existing ESA and NASA standard models, which include the Mission Operations Center (MOC), the Science Operations Center (SOC), the Data Processing Center (DPC), etc. The data processing pipeline connects between SOC and DPC. The SOC obtains the level-0 data from MOC and DPC performs the data processing and distributes the level-2 and level-3 data to SOC. For TAIJI-1 mission, SOC and DPC are two subsystems, which are included into the named science application system (SAS). That is the one of the six-function systems, which operate Chinese space mission. MOC is relevant to the ground support system (GSS) and spacecraft control system, that are also the ones of six-function systems of Chinese space mission. The on-orbit experiment plannings are transported from SAS to GSS, that is similar to from SOC to MOC in NASA standard models. The computer construction and computer software are the basic elements of the SAS, that are constructed completely, before the TAIJI-1 was launched. After TAIJI-1 enters the orbit, the data processing pipeline begins to work and the experimental items of TAIJI-1 are performed in the pipeline. The basic functions, performances and optimization functions of the detection devices in the payloads are verified completely 3 months after launch. In the same time, the methods of data analysis and processing are also verified. As a result, the required indicators of key techniques of the spacecraft for the gravitational wave detection are justified. The data processing pipeline is also reasonable. The relevant codes for data analysis and processing will benefit the next stage of TAIJI Program.
