Abstract

The invention relates to a laser / microwave comprehensive measurement and control data transmission method and a data transmission station, and the method comprises the steps: S1, enabling the data transmission station to be distributed in a near space, wherein the data transmission station comprises a laser measurement and control data transmission system, a microwave measurement and control datatransmission system, and a receiving and transmitting signal processor connected with the laser measurement and control data transmission system and the microwave measurement and control data transmission system; s2, enabling the data transmission station to perform information transmission with an on-orbit satellite through the laser measurement and control data transmission system, and enablingthe data transmission station to perform information transmission with a ground station through the microwave measurement and control data transmission system, wherein the transceiving signal processor is used for mutually converting information in the laser measurement and control data transmission system and information in the microwave measurement and control data transmission system. Accordingto the scheme, the respective advantages of laser and atmospheric transmission are better utilized, the respective defects are avoided, and efficient measurement and control data transmission of theground to the satellite can be achieved.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a laser / microwave comprehensive measurement and control data transmission method and a data transmission station. Background technique [0002] In the process of communication between the spacecraft and the ground, microwave or laser is usually used for communication. Among them, the higher the microwave or laser frequency, the larger the bandwidth available for communication transmission. Microwave and laser wireless communication transmission have their own advantages and disadvantages. Microwaves have a relatively narrow transmission bandwidth and wider beams, which are less affected by the atmosphere in comparison. The laser has a relatively wide transmission bandwidth and a small beam divergence angle, but it is significantly affected by the atmosphere. [0003] At present, both microwave and laser methods are used in satellite-ground measurement and control data trans...
