Abstract

The present invention relates to a laser / microwave comprehensive measurement and control data transmission method and a data transmission station, wherein the method includes: S1. Arranging a data transmission station in an adjacent space, the data transmission station includes a laser measurement and control data transmission system, a microwave measurement and control data transmission system system and a transceiver signal processor connected to the laser measurement and control digital transmission system and the microwave measurement and control digital transmission system; The data transmission station performs information transmission with the ground station through the microwave measurement and control digital transmission system; wherein, the transceiver signal processor performs information on the information in the laser measurement and control digital transmission system and the information in the microwave measurement and control digital transmission system convert each other. This scheme makes better use of the respective advantages of laser and atmospheric transmission, avoids their respective shortcomings, and can realize efficient measurement and control data transmission from the ground to the satellite.

Description

Technical field [0001] The present invention relates to the field of aerospace technology, in particular to a laser / microwave integrated measurement and control digital transmission method and a data transmission station. Background [0002] In the process of communication between space vehicles and the ground, microwaves or lasers are usually used for communication. Among them, the higher the microwave or laser frequency, the greater the bandwidth that can be used when communicating. Microwave and laser wireless communication transmission have their own advantages and disadvantages. Microwaves have a relatively narrow transmission bandwidth and a wider beam, which is less affected by the atmosphere in comparison. The laser has a relatively wide transmission bandwidth, and the beam divergence angle is small, but it is more obviously affected by the atmosphere. [0003] At present, when the satellite and ground measure and control digital transmission, microwave and laser are a...
