Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide a method and system for processing satellite full-cycle multi-source telemetry data. Because the format of the remote measurement data is not uniform, it cannot be processed in a unified manner, or even can not be processed. The present invention uses a unified calculation method for various types of telemetry data from different satellites, and realizes the integration of all types of telemetry data processing.

Embodiment Construction

[0068] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0069] like Figure 1 to Figure 4 As shown, the processing method of satellite full-cycle multi-source telemetry data of the present invention comprises the following steps:

[0070] Step 1. Obtain the phase of the satellite corresponding to the telemetry data to be processed (ground test phase, in-orbit operation phase), and the source of telemetry data (measurement and control channel, data transmission channel).

[0071] Step 2: Determine the format conversion requirements of the telemetry data. If format conversion is required, determine the format conversion method. If it is the ground test stage, and the telemetry data obtained through the measurement and control channel does not need to perform format conversion, directly perform step 4; if For the telemetry data stored in the te...

Abstract

The invention discloses a processing method and a processing system for satellite full-cycle multi-source telemetry data. The method includes the following steps: Step 1: Obtain the stage of the satellite and the source of the telemetry data corresponding to the telemetry data to be processed; The format conversion requirements of the telemetry data are judged, and if the format conversion is required, the format conversion method is determined; in step 3, according to the analysis result of step 2, the format conversion method of the telemetry data obtained by the data transmission channel or the telemetry data format of the satellite in-orbit measurement and control channel is executed. The conversion method converts the data format into the general telemetry data format of the satellite comprehensive survey system. The invention solves the problem that the prior art cannot uniformly process the telemetry data of the whole life cycle of the satellite in the ground test stage and the orbit operation stage. The present invention can effectively carry out generalized design, and different satellites only need to provide telemetry parameter processing parameter information to realize the state analysis of the whole life cycle of the satellite.

Description

technical field [0001] The invention relates to the field of satellite data processing, in particular to a processing method and system for satellite full-period multi-source telemetry data. Background technique [0002] Satellite telemetry data analysis is the main means to understand the status of satellites. With the development of satellite research and development technology, satellite telemetry continues to be refined. In addition to real-time telemetry data collected and transmitted in real time, after the entire satellite telemetry collection and framing are completed, the telemetry data will be Stored in the corresponding data storage area to form various storage telemetry data, such as CTU (control unit) storage segment telemetry, telemetry storage telemetry, memory unloading telemetry, etc., to realize satellite operation process monitoring or post-processing analysis, and the transmission path of telemetry data is also With continuous development, TT&C channel te...
