Description
Technical Field

Background
In order to verify the overall design of the payload subsystem, detect the matching of electrical interfaces and data interfaces between a load and a satellite platform and between load equipment, and confirm the correctness and rationality of the function, performance and working mode design of the integrated payload subsystem, comprehensive and sufficient ground test and verification work of the payload is required to be carried out in each stage of initial sample, normal sample and the like of payload development. The system for supporting the load to complete the test task is a payload ground comprehensive test system.
The ground comprehensive test system for the effective load and the ground comprehensive test system for the satellite are mainly different in that tested objects with different types of tasks have large differences: the satellite system generally comprises energy, thermal control, attitude control, data management, measurement and control and other systems, and the satellites developed by the same development unit, particularly series of batched spacecrafts, are configured with the subsystems generally having inheritance. However, the payloads configured on different spacecrafts often span multiple disciplines such as remote sensing, meteorology, astronomy, life, materials and biology, and great differences exist in the aspects of functions, performances, interfaces, working modes and the like. Secondly, the test data types are various, the complexity of the processing algorithm is high, and the difference is large: the satellite platform data only comprises engineering and telemetry parameters, the processing requirements of the satellite platform data are mostly physical quantity inversion requirements such as voltage, current, temperature, pressure and angle, the load data comprises engineering and telemetry parameters, and the load data also comprises image data, energy spectrum data, case data and elevation data, and the data often has the processing requirements of high complexity and large difference such as data splicing, decompression and color restoration.

For a test task of a new type of payload, a corresponding ground comprehensive test system is required to be newly constructed. On one hand, the development mode prolongs the development period of the test system, and wastes resources such as equipment, personnel and the like, and on the other hand, the developed test system has no inheritance, so that the high availability and the high reliability of the test system are difficult to ensure.
