Method for storing on-orbit data of spacecraft in unified way

Abstract

The invention discloses a method for storing on-orbit data of a spacecraft in a unified way. The method comprises the following steps of: firstly, receiving the on-orbit data from the spacecraft by adopting an XML format; secondly, defining various calculation results and on-orbit operation information of the spacecraft according to the XML format, wherein the various calculation results and on-orbit operation information comprise calculation result and on-orbit operation information serial numbers, calculation result and on-orbit operation information names, version numbers and XML description words; thirdly, defining each calculation result and various data attributes of the on-orbit operation information according to the XML format, wherein the calculation results and various data attributes of the on-orbit operation information comprise calculation result and on-orbit operation information serial numbers, unit serial numbers, unit names, XML description words, data types and storage length; fourthly, generating a data table for storing the calculation results and the on-orbit operation information according to the definitions in the second step and the third step; and fifthly,analyzing XML data on the network, searching the data table generated in the fourth step according to XML information and storing the calculation results and the on-orbit operation information in corresponding fields of the data table.

Description

technical field [0001] The invention relates to a unified storage method for spacecraft on-orbit operation information and calculation results of control quantities. Background technique [0002] There are various types of information involved in spacecraft on-orbit management, including on-orbit telemetry data, remote control commands, injection data, orbital elements, calculation results of control quantities, spacecraft fault processing decision information, and spacecraft fault processing plans. According to the characteristics of spacecraft in-orbit data, these data can be divided into two categories: [0003] 1. Telemetry data: The data format of this type of data is fixed, the data changes slowly, but the amount of data is large, and the storage and query timeliness requirements are high. [0004] 2. Calculation results and on-orbit operation information data: This kind of data has a small amount of storage, but there are many types of data, and the data formats are ...
