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 ...

Abstract

The invention discloses a satellite-borne data management method based on an AOS standard, which comprises the data packaging step and the scheduling and sending step. In the data packaging step, service packages are carried out respectively for platform data, service data and experimental data. In the scheduling and sending step, VCDU (Virtual Channel Data Unit) data generated by the data packaging step is scheduled and sent in priority. The invention further discloses a satellite-borne data management device based on the AOS standard. The device comprises a data packaging unit, a data scheduling unit, a three-level service coding unit and a second-level service coding unit. The data packaging unit comprises a first data packaging unit, a second data packaging unit and a third data packaging unit. The data scheduling unit comprises a first-level scheduling unit and a second-level scheduling unit. The method and device provided by the invention can be used to package and schedule various data formats generated by satellites, and accordingly, the data transmission efficiency and the channel utilization ratio of satellites are improved.

Description

technical field [0001] The invention relates to an on-board data management method and device based on the AOS standard. Background technique [0002] AOS is a standard formulated by the International Space Data System Consultative Committee for manned spaceflight activities in the late 1980s. Detailed provisions. With the development of aerospace technology, this standard has been widely used in various types of foreign spacecraft. At present, domestic spacecraft mostly adopt the traditional system when designing the on-board data system. The entire satellite information flow is designed separately according to the two channels of measurement and control and data transmission. The measurement and control channel adopts the conventional PCM telemetry system and is responsible for organizing and processing the entire satellite. platform data; the data transmission channel adopts part of the AOS standard system, and is mainly responsible for organizing and processing busines...
