Problems solved by technology

[0007] 1) The measurement and control system and the data transmission system are implemented on different channels and managed separately, which not only increases the development cost of the upper equipment
[0008] 2 The stand-alone machines of measurement and control and digital transmission are separated, and there are many types of supporting stand-alone machines, making it difficult to control the technical status;
[0009] 3) The weight, volume and power consumption of the system are not dominant, the electromagnetic compatibility is poor, and the power utilization efficiency is low

Embodiment Construction

[0089] Specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0090] Such as figure 1 Shown is the flowchart of the present invention, figure 2 Described is the principle block diagram of the present invention, by figure 1 with figure 2 As can be seen, a kind of measurement and control digital transmission integration method based on Turbo coding that the present invention proposes, the implementation steps are as follows:

[0091] (1) According to the system clock fs (55.974MHz), spread spectrum pseudo-code frequency fg (10.23Mbps) and coded symbol rate ft (3Mps / 1.5Mps) under the integrated system of measurement, control and digital transmission, determine the intermediate clock variable fi (16Hz) . Let fs=K1×fi, ft=K2×fi, fg=K3×fi, fi=K4×2Hz. Among them, K1, K2, K3 and K4 are natural numbers, and complete the unified system clock domain management under the two systems compatible with ...

Abstract

The invention discloses an integrative method of measurement, control and data transmission based on Turbo coding, which utilizes isochronous insert business in an AOS (Advanced Orbiting System) protocol, is combined with characteristics of an incoherent spread spectrum measurement and control system, solves a problem of unified channel fusion during distance measurement, speed measurement and measurement and control of high-speed data transmission, and establishes a reliable and stable link for remote metering, remote control, distance measurement, speed measurement and high-speed data transmission between a satellite and the ground. In comparison with the current situation of adoption of measurement and control type and data transmission type single separation in the existing satellite technology, integrated, light and miniaturization design of a single machine assorted with the system is implemented, and the method has wide application prospect in the aspect of implementing high-speed data transmission at medium or low earth orbit satellite by utilizing a measurement and control channel.

Description

technical field [0001] The invention relates to an integrated method of measurement, control and digital transmission based on Turbo coding, which solves the problem of unified channel fusion for measurement and control of distance measurement and high-speed data transmission, and establishes reliable and stable telemetry, remote control, distance measurement and speed measurement between satellites and ground. High-speed data link. It is mainly used on various medium and low orbit satellite spread spectrum measurement and control platforms, and belongs to the field of satellite measurement and control and communication technology. Background technique [0002] At present, my country is launching more and more small satellites, and the number of satellites in orbit is also increasing. To manage multiple satellites in orbit at the same time, the current working mode will not meet the requirements. Therefore, it is one of the effective means to simplify the equipment to share...
