Embodiment

[0032] Taking the navigation satellite control propulsion sub-system, the mode of joint interpretation of the sun capture mode and the mode word as an example, the specific implementation mode of the present invention is further described.

[0033] After completing the loading of the database driver and the connection between Matlab and the telemetry database, define the following query conditions:

[0034] Query conditions: select the word mode and measure attitude and measure angular velocity.

[0035] Query time range: the start time is 9:23:00, July 9, 2011; the end time is 9:31:48, July 9, 2011.

[0036] According to the above determined query conditions and query time range, extract the telemetry data that meets the query conditions and time range, and then use the following interpretation method to generate a task table.

[0037] Define the measured attitude and mode character, the measured angular velocity and the mode character in two curves respectively. Among them...

Abstract

The invention discloses a method for interpreting telemetry data of a navigation satellite control system, which is used for extracting and judging telemetry data in a navigation satellite telemetry database, comprising: a step of connecting Matlab to the telemetry database; using Matlab to determine the telemetry data to be interpreted steps; steps for plotting telemetry data. The invention realizes the automatic interpretation of the remote measurement data.

Description

technical field [0001] The invention relates to a technology for interpreting telemetry data of a satellite control system, in particular to a method for interpreting telemetry data of a navigation satellite control system. Background technique [0002] A large amount of test data, including analog and digital, will be generated during the test of the navigation satellite control subsystem. These data are the most important basis to reflect the function and performance of the satellite control system, so a comprehensive inspection of the generated data is required. Traditional inspection methods require testers to observe the test data in real time during the test process, search the query database for the telemetry data during the entire period, and manually interpret whether the results are consistent with the theoretical values. This method is time-consuming and labor-intensive, and has poor real-time performance. Contents of the invention [0003] The problem solved b...
