Design of Payload Integrated Testing System for First Mars Exploration Mission in China

Test matrix of payload subsystem for first Mars exploration Mission in China and technical requirements of integrated testing system are introduced. In view of requirements of testing tasks for 2 spacecraft and 5 testing scenes,3 layers of unified architecture composed of interface adaptation,business processing and data management are designed,which helps testing system achieve the adaption of external interface and functions for different testing scenes. According to payload scientific data processing and transmission mechanism on orbit,scientific data processing flow is designed for the testing system,which meets different requirements for 13 kinds of payloads. According to the high dimension characteristics of 1 900 dimension engineering telemetry parameters and 400 data injection instructions,the software based on rules for automatic data discrimination is designed,which makes all parameters and data injection instructions can be checked intelligently. The task execution results show that the system meets the needs of payload testing tasks under different modes,and effectively ensures the smooth implementation of payload test tasks.
