Problems solved by technology

However, the disadvantage of this method is that the extraction at a large ratio leads to the loss of important telemetry parameters between the extraction intervals, and a large number of telemetry parameters are discarded to reduce the amount of delayed telemetry data. Observing the working status of the arc section affects the accurate judgment of faults, rapid positioning and formulation of countermeasures

example 1

[0035] Example 1: Parameters such as the output voltage of the power converter of the power supply and distribution subsystem are common parameters, and the real-time telemetry is 8 seconds / time, which is extracted according to the ratio of 4:1, that is, 32 seconds / time, to generate the delay of the power supply and distribution subsystem telemetry data. If the ground needs to obtain higher frequency data, it can send a remote command to change the extraction ratio to 2:1. After receiving the instruction, the on-board computer extracts according to the ratio of 2:1, which is changed to 16 seconds / time.

example 2

[0036] Example 2: Parameters such as power supply voltage, fixed discharge power, and fixed discharge current of each equipment in the measurement and control subsystem are common parameters. System delay telemetry data.

example 3

[0037] Example 3: Parameters such as the power supply voltage and calibration level of each device in the data management subsystem are common parameters, and the real-time telemetry is 8 seconds / time, which is extracted according to the ratio of 4:1, that is, 32 seconds / time, to generate the delay of the data management subsystem telemetry data.

Abstract

The invention relates to a spacecraft autonomous delay telemetering method adapted to parameter characteristics. The method includes the following steps of: (1) classifying telemetering parameters of a spacecraft into a key parameter, a common parameter, an autonomous management alarm parameter, a command parameter, a constant value parameter, a key monitoring parameter and scientific test data according to the characteristics of the telemetering parameters; (2) processing the parameters respectively according to the characteristics of the parameters so as to optimize the storage resource and the downlink channel resource of the spacecraft; (3) distributing different storage areas for various delay telemetering data respectively by using a spaceborne computer to store; and (4) determining the delay telemetering download method by using the spaceborne computer according to the remote control command transmitted by a ground measuring and control station and storing and downloading the delay telemetering data.

Description

technical field [0001] The invention relates to a method for processing and downloading time-delay telemetry of a spacecraft, and belongs to the technical field of telemetry of spacecraft. Background technique [0002] Spacecraft telemetry is a measurement technology that obtains parameters such as the working state and environment of the spacecraft on the ground. Real-time telemetry is a spacecraft telemetry method that sends the collected telemetry data to the ground measurement and control station immediately; delayed telemetry is to store the collected telemetry data in the on-board storage device, and wait for the spacecraft to fly through the range of the ground measurement and control station ( The spacecraft telemetry mode sent when the arc can be observed). [0003] For the geostationary orbit spacecraft, it is stationary relative to the ground measurement and control station, and the ground measurement and control station can receive the spacecraft telemetry data ...
