Satellite telemetry data reduction processing method

Abstract

The invention discloses a satellite telemetry data reduction processing method. Firstly, satellite test basic configuration information is stored in a basic database, based on the configuration information in the basic database, the test command sequence is compiled by imaging interface according to satellite test requirement and stored in the basic database; the command is transmitted to the satellite according to the test command sequence, and the satellite issues telemetry parameter true codes to a ground test network; the telemetry parameter true codes are resolved into corresponding engineering values according to the data resolving mode stored in the basic database again to be stored in a real-time database; and finally, the modification items of the telemetry parameter resolving mode is automatically mapped into the real-time database. The inventive method can realize image display of the test process and the batching of test process compilation, ensure the consistency of data in the test process and the completeness of data when updating configuration resolving mode. In the test, the progress of the whole system is not stopped, the system interpretation can be executed according to the preset test rule, and the automation of the test can be realized.

Description

technical field [0001] The invention relates to a processing method for automatically parsing acquired telemetry data streams during a satellite whole-satellite test. Background technique [0002] The purpose of satellite test telemetry data processing is to fully and effectively reflect the current operating status of the satellite under test in the shortest possible time. Through these parameters, it can intuitively reflect the status of the satellite after receiving instructions and take corresponding actions. The parameters can be used to locate The equipment problems and design flaws in satellite operation give valuable and reliable test conclusions. [0003] At present, in the process of automated testing, when organizing and implementing model testing tasks, it is necessary to check the real-time original code and engineering values ​​of the telemetry parameters of the whole star at any time, compare the changes of relevant telemetry parameters before and after the co...

Problems solved by technology

In actual work, because the test process needs to be adjusted according to the status of the satellite, the writing of the test process is a lot of work, errors are prone to occur during repeated operations, the intuition is poor, and it cannot be directly called by the test software;

[0005] (2) Parameters and instructions are configured in text form. For each application software and real-time database, corresponding configuration tables are stored separately, and the data integrity and uniqueness of the test process are poor.

The same configuration information may be stored repeatedly in several places. Due to incomplete updates or human factors, data inconsistencies may occur between different copies of the same data, which affects the accuracy of the test;

[0006] (3) The modification of the configuration table during the test is basically completed by copying and overwriting mainly by humans, and the automation level is poor

With the continuous increase of test tasks, this manual update method is increasingly unable to adapt to modern test requirements.
