Abstract

The invention provides an airborne terminal compatible with dual-system satellite communication link work. The airborne terminal comprises a down-conversion channel module, an up-conversion channel module, a frequency synthesizer module and a signal processing module, wherein the down-conversion channel module converts a received inter-satellite link forward remote control signal of a Beidou second generation satellite into an intermediate frequency signal and sends the same to the signal processing module, and the signal processing module captures and demodulates the intermediate frequency signal and outputs remote control information; airborne telemeasuring data are encoded and modulated by the signal processing module and are sent to the up-conversion channel module to be converted into a radio frequency signal sent to the Beidou second generation satellite, and meanwhile, the signal processing module receives a switching instruction signal input by an airborne platform, generates a control signal of the frequency synthesizer module through built-in dynamic loading working software, controls the frequency synthesizer module to output a local oscillation signal corresponding to the frequency of an inter-satellite KSA link of a relay satellite system and switches the inter-satellite link working mode of the Beidou second generation satellite to the inter-satellite link of the relay satellite system.

Description

technical field [0001] The invention relates to an aircraft-mounted terminal provided for the operation of a dual-system satellite link compatible with a relay satellite / BeiDou second-generation satellite in the field of measurement and control communication. Background technique [0002] With the continuous increase of satellite resources, the use of satellite communication to achieve cross-regional over-the-horizon data transmission technology has received more and more attention, and has become a key way to transmit various information in real time and effectively. For various medium and low-orbit vehicles, it is difficult to transmit platform information directly to the ground due to the curvature of the earth. The inter-satellite KSA link of my country's relay satellite system and the inter-satellite link of the Beidou second-generation satellite system use two completely different sets of communication signals, including signal operating frequency, signal waveform and ...
