Problems solved by technology

[0005] The telemetry signal quantization in the prior art only has an 8-bit quantization method. Although it is simple to implement, it cannot meet the user's more detailed monitoring requirements for some key parameters, let alone make full use of the limited channel capacity to realize various monitoring methods.

Embodiment Construction

[0016] The telemetry signal quantization method of the present invention will be described in further detail below in conjunction with the accompanying drawings, specifically the following implementation manners.

[0017] The telemetry signal quantification method of the present invention expands the data quantization precision, enriches the quantification means, and uses the on-track programming technology to dynamically select the quantization digits of any telemetry parameter without changing the hardware connection, which not only saves hardware resources, and improve the accuracy of telemetry data. The programmable number of telemetry parameter quantization digits realizes the key monitoring of important parameters, and transmits the most effective telemetry parameters in the limited channel capacity, which meets the different needs of telemetry monitoring at different stages.

[0018] In this embodiment, the telemetry parameter quantization digits of the telemetry signal...

Abstract

The invention provides a remote signal quantization method which at least comprises the following steps of: setting at least one low-precision quantization bit grade and at least one high-precision quantization bit grade; and according to different demands on different remote signal parameter precisions, selecting one of the low-precision and the high-precision quantization bit grades, and carrying out corresponding remote signal processing according to the selected quantization bit grade. By adopting the remote signal quantization method provided by the invention, 12-bit quantization precision is added on the basis of the traditional 8-bit quantization precision, and dynamic selection is carried out on any remote parameter between an 8-bit quantization mode and a 12-bit quantization mode so that monitoring requirements on different users and operation stages are met.

Description

technical field [0001] The invention relates to satellite signal measurement and control technology, in particular to a remote measurement signal quantization method suitable for remote control by an earth station and capable of dynamic on-orbit programming of the quantization digits of the remote measurement signal. Background technique [0002] Telemetry signals play a very important role in the development and operation of satellites. During the development and test process, it is necessary to use telemetry signals to monitor the engineering physical parameters and working status of each subsystem instrument and equipment, and then provide a basis for the verification environment, evaluation and design performance of each subsystem and further improvement of the design; during the flight process In the process, it is necessary to monitor the environment and the working status of each sub-system instrument and equipment through telemetry signals to complete the on-orbit me...
