Abstract

The invention discloses a satellite telemetry data treatment system and a realization method of the system, which solves the problems of telemetry data treatment, such as universality, extensibility and cross-platform. The system comprises a log module, a pointer container module, a memory management module, a basic data management module, a configuration information management module, an index table management module, a data pretreatment module, a treatment method module, a data analysis module and a data initialization and management module. The method comprises preparing configuration file and basic data, and creating a frame index table or a packet index table by use of a dynamic array, i.e. pointer container; receiving telemetry data, and carrying out effective judgment and data integration; carrying out parameter treatment, and treating the parameter result according to a manner defined by a customer; and stopping until all of the telemetry data is treated.

Description

technical field [0001] The invention belongs to the field of satellite telemetry, and relates to a satellite telemetry data processing system and its realization method. Background technique [0002] The main task of the telemetry data processing system is to complete the processing, interpretation, storage and broadcasting of various telemetry data of different types of satellites, and it exists in the form of an independent, cross-platform software toolkit. [0003] During the electrical performance test phase of the spacecraft, telemetry parameters are the main way to monitor the working status of spacecraft components, so the processing of telemetry data is one of the core functions of the whole satellite ground test equipment. However, the currently used telemetry data processing system mainly has the following deficiencies: (1) Due to the various needs of the structures and functions of various types of satellites, the formats of the telemetry data they download are no...
