Embodiment Construction

[0033] 1. Original code calculation elements

[0034] An abstract calculation formula of the original code is as follows:

[0035] Vp=f(Coef, Raw, AssoVp)

[0036] The above formula contains all 5 elements of the original code calculation, of which:

[0037] (1) Vp represents the result of one calculation of a certain telemetry parameter;

[0038] (2) f() represents the calculation method determined in advance for a certain Vp, such as linear calculation formula, temperature calculation formula, etc.;

[0039] (3) Coef represents the formula coefficient, which is also determined in advance for a specific parameter;

[0040] (4) Raw represents the original code. For a certain Vp, as the satellite telemetry original code data frame is continuously downloaded, Raw will continue to change with time during the calculation process, resulting in different Vp, which is a time-varying parameter;

[0041] (5) AssoVp represents the associated parameter value, which means that the telemetry parameter ...

Abstract

The invention discloses a telemetry data processing method, belonging to the technical field of satellite telemetry and remote control. The telemetry data processing method comprises the steps of: preprocessing true forms of satellite download data; processing a format formed after preprocessing into queues and managing the format queues; and extracting data frames in the format queues. Accordingto the invention, the true forms of different formats in multi-spacecraft telemetry data can be processed uniformly.

Description

Technical field [0001] The invention belongs to the technical field of satellite telemetry and remote control, and relates to a method for processing telemetry data. Background technique [0002] In order to understand the operating status of the satellite in orbit, it is necessary to process the original telemetry data transmitted by the satellite, and calculate the engineering values ​​of the telemetry parameters, such as temperature, current, and voltage. The basic steps of spacecraft telemetry source code data processing, taking the calculation of a certain temperature on the satellite telemetry parameter value PT as an example, first need to extract the parameter from the specified position in the original code according to the encoding method of the specific spacecraft telemetry source code data The corresponding byte data (called the original code addressing), and then the obtained data is brought into the special calculation formula of PT, and after calculation, the tempe...
