After introducing the application scenario and the design concept of the embodiment of the present application, the following describes a technical solution provided by the embodiment of the present application.
As shown in fig. 3, an embodiment of the present application provides a method for multi-satellite management and control data information distribution, including:
step 101: configuring a distribution strategy of the satellite control data according to the link establishment and package processing requirements of the satellite control data in the measurement and control plan;

The transmission protocol comprises: UDP protocol, TCP protocol, FTP protocol, DDS transmission and message queue transmission; different protocols are suitable for different data types, wherein a UDP (user Datagram protocol) protocol is adopted for satellite telemetry data distribution, an FTP (file transfer protocol) protocol is adopted for zip data packet distribution, and DDS (direct digital Synthesis) is adopted for data among services.
Step 102: and processing and distributing the received satellite data products sent by the measurement and control station or the information products sent by the user center according to the configured distribution strategy.
Wherein the satellite data product comprises: satellite telemetering data, satellite data transmission data, satellite external survey data and remote control data:
the satellite telemetry data are telemetry data frames descending from the spacecraft, the data frames are analyzed and processed in the system, and then the processing result is distributed to other components of the operation control information management system. As a first procedure for telemetry data analysis, a telemetry data processing system plays a very important role.
The downlink data processed by the telemetry data processing system is mainly telemetry data frames in a CCSDS standard format, and the data is transmitted to telemetry data processing software in a data stream mode. And the data processing software receives the data and then carries out unpacking processing to obtain the final telemetering parameter data.
A general telemetering data processing system adopts a centralized data processing mode to receive, process and distribute data. The receiving and the analysis of the telemetering data frame are executed in the same process, and the data of different virtual channels are not distinguished in the processing process of the data frame. The original data processing system is processed by a unified data analysis thread, so that the pressure on a CPU is very large, and as the process of data analysis is concentrated, for a telemetering data frame with lower downlink rate, the data receiving rate of the processing system can be consistent with the downlink rate of the telemetering data, and if the downlink rate is 20Mbps, the data processing system can ensure that all telemetering data frames are completely received and has better processing results; however, for a telemetry data frame with a high downlink rate, the loss of the original data frame may be caused due to a large difference between the downlink rate of the data and the data receiving rate of the data processing system.
