Problems solved by technology

Restricted by bandwidth capacity, UAVs must switch between multiple simultaneous loads when performing large-scale operations such as surveillance, surveying, and mapping. Real-time video or image data is compressed at a large rate to realize real-time air-to-ground data mutual transmission through limited data bandwidth, and the bandwidth of Ku-band is frequency division multiple access. Applying for services to Satcom means exclusive service for fixed-frequency bandwidth, occupying This frequency will cause a waste of this bandwidth during idle time, and the rental fee will be very high

Abstract

The invention discloses a Ku and Ka dual-frequency satellite communication link device, comprising: an antenna assembly, a power amplifier assembly and a transceiver assembly; the antenna assembly is used to receive ground remote control signals, and perform Ku and / or Ka down-conversion on the ground remote control signals Processing, sending the C intermediate frequency signal after Ku and / or Ka down-conversion processing to the transceiver component; and, sending the airborne telemetry signal after Ku and / or Ka up-conversion processing to the satellite; the transceiver component is used for The C intermediate frequency signal is sent to the airborne mission management computer; and, receiving the airborne telemetry signal sent by the onboard mission management computer, the airborne telemetry signal is sent to the power amplifier assembly; the power amplifier assembly is used to perform Ku and / or the airborne telemetry signal or Ka up-conversion processing, sending the airborne telemetry signal after Ku and / or Ka up-conversion processing to the antenna assembly. The invention solves the problems existing in the single Ku or single Ka frequency band link communication of medium and large UAVs at present.

Description

technical field [0001] The invention belongs to the technical field of satellite communication, and in particular relates to a Ku and Ka dual-frequency satellite communication link device. Background technique [0002] Satellite communication is an important component of UAV data link communication technology. With the increasing scarcity of traditional Ku-band orbit and frequency resources, high-throughput broadband satellite communication technology will become the development direction of Satcom. Most of the current communication satellites are equipped with Ku and Ka frequency band transponders, which can realize Ku and Ka dual-mode simultaneous work under the condition of pointing to the same satellite. [0003] At present, the typical data bandwidth transmitted by the Ku-band (10.7-18.1GHz) satellite communication system used on UAVs is 2M / 4M / 8M. Restricted by bandwidth capacity, UAVs must switch between multiple simultaneous loads when performing large-scale operatio...
