Method for telemetering of advanced orbiting system (AOS) of distributed framework satellite

Abstract

The invention provides a method for telemetering of an advanced orbiting system (AOS) of a distributed framework satellite. A distributed satellite framework is adapted on a telemetering information flow collection, thus telemetry parameters with strong correlation are acquired in a centralized mode in the form of module and form AOS telemetering source packets. A quick acquisition and transmission method in which downloading rate is higher than normal downloading rate is adopted in an acquisition and transmission links, and a host computer realizes an AOS framing function and a deployment function of telemetering strategies. When the telemetering strategies are changed, information exchange procedures and hardware processing procedures in the acquisition, transmission and processing links can be simplified, thus reducing the risk of timing sequence disorder. In the process of deploying the strategies, the demands of satellite telemetering are searched sufficiently, and a deployment strategy with combination of normal telemetering, quick telemetering and slow telemetering is put forward and inserted into domain multiplexing telemetering at stages, thus preferably meeting the demands of the satellite telemetering.

Description

technical field [0001] The invention relates to a satellite telemetry method. Background technique [0002] The Advisory Committee on Space Data Systems (CCSDS) recommends protocols ranging from conventional packet telemetry to the Advanced On-Orbit Data System (AOS). At present, the telemetry of complex space missions is based on the telemetry recommendations in AOS to carry out space data link design work. [0003] my country's future satellite platform will develop towards the distribution structure of distributed electronic equipment, which brings a good opportunity for the transformation of telemetry mode, changing the shackles of PCM fixed-format telemetry in the past, and adopting the telemetry mode based on AOS telemetry can increase telemetry. Practicality, flexibility, while reducing the heavy burden of redesign caused by system replacement. [0004] For AOS, the content of the proposal is mainly the implementation method of the data link layer of the communicatio...

For example, in the 11th National Symposium on Remote Sensing, Telemetry and Remote Control in 2008, the Xi’an Institute of Surveying and Mapping published a paper titled "The Application of CCSDS in High-resolution Earth Observation Satellites", which explained how remote sensing satellites are used in the design of telemetry source packages and allocation strategies. and other design methods, focusing on the compression and transmission of image data, its disadvantages are that the telemetry method is single and the versatility is not strong
