Embodiment 1
[0039] Such as figure 1 Shown is the flow chart of the method of the present invention, including the steps of data encapsulation and scheduling and sending.
[0040] The data generated by various equipment of the spacecraft can be divided into low-speed data, medium-speed data and high-speed data according to the type of data source. Among them, the low-speed data includes attitude and orbit data, DORIS data, laser tracking data and telemetry data of the whole star, which is the platform data of the spacecraft. Medium-speed data includes data generated by radar altimeter, microwave radiometer, microwave scatterometer, calibration radiometer and mechanical environment monitoring, which is the operational data of the spacecraft. The high-speed data includes LVDS test data and 1394 bus test data, which serve the laser communication test and are the test data of the spacecraft. Therefore, for different data types, the step of data encapsulation is further divided into a first d...
Embodiment 2
[0083] Such as Figure 7 Shown, this is based on the schematic diagram of the device of the method of the present invention. It includes a data encapsulation unit, a data scheduling unit, a third-level service encoding unit, and a second-level service encoding unit, wherein the data encapsulation unit includes a first data encapsulation unit, a second data encapsulation unit, and a third data encapsulation unit; The scheduling unit includes a first-level scheduling unit and a second-level scheduling unit.
[0084] The data encapsulation unit includes a first data encapsulation unit, a second data encapsulation unit and a third data encapsulation unit corresponding to the first data encapsulation step, the second data encapsulation step and the third data encapsulation step respectively, for respectively following the corresponding The data encapsulation step encapsulates the platform data, business data and experimental data. The platform data VCDU data packets and business ...
