A satellite telemetry decoding system

Abstract

The invention relates to a satellite telemetering decoding system, comprising a basic data allocation module, an allocation initialization module, a data source adaptation management module, a telemetering preprocessing management module, a decoding dispatching management module, an algorithm library management module and a telemetering output module. The data source adaptation management module is internally provided with a plurality of external data source conversion interfaces, supports expansion, can convert the data of any standard format into system defined telemetering frame data, and automatically adapts to dock with various satellite ground receiving equipment. The telemetering preprocessing management module is internally provided with a plurality of telemetering types of decoding mechanisms, and can support multiple types of satellite decoding flexibly according to satellite basic configuration. The decoding dispatching management module is internally provided with a thread pool mechanism. Due to multi-thread concurrent processing, the efficiency of telemetering decoding is greatly improved. The system can be copied and used directly due to the configurable satellite basic information and the expandable algorithm library, thereby saving more manpower and material resources.

Description

technical field [0001] The invention relates to a decoding system, in particular to a satellite telemetry decoding system, which belongs to the field of satellite telemetry decoding. Background technique [0002] At present, the number of satellite launches in my country is increasing year by year, and the types of satellites are also becoming more and more abundant. As a necessary means for ground understanding and monitoring of satellite functions and operating status, telemetry decoding should of course catch up with the times and make contributions in terms of applicability and efficiency. [0003] Due to the diversity of satellite functions, the downlink telemetry formats and telemetry parameter channels are also different, and the corresponding ground satellite telemetry decoding must also adapt to this change. At present, telemetry decoding basically adopts a set of decoding schemes for one star or a series of stars. The decoding system accepts external decoding data ...

Problems solved by technology

This method is currently commonly used, and it is highly coupled with satellite features. Even if the telemetry parameter algorithm changes, the code may need to be re-modified. In addition, the existing decoding system only supports one decoding method, which cannot be used in frame telemetry and packet Switching between telemetry, this method is not easy to transplant and generalize the decoding system, and the serial processing of internal logic will have a certain impact on the decoding efficiency, which will inevitably increase the operating cost of the satellite and the complexity of decoding, which is urgently needed A method for automatically identifying satellite telemetry formats and efficiently parsing telemetry parameters
