The embodiment of the invention discloses an onboard satellite communication modulator-demodulator for unmanned aerial vehicle power line inspection and is used for solving the technical problem that a traditional unmanned aerial vehicle satellite communication modulator-demodulator is relatively low in total transmission efficiency, relatively low in demodulation / modulation capability and relatively poor in interference resistance and is difficult to ensure the wide area communication capability of a carrying vehicle under complex terrain and meteorology conditions. The embodiment of the invention comprises a modulation / demodulation module, an integrated service processing module, a secret unit and a power supply. The modulation / demodulation module is connected with the integrated service processing module and is used for modulating and demodulating processed content of the integrated service processing module. The secret unit is connected with the modulation / demodulation module and is used for encrypting the modulated and demodulated content of the modulation / demodulation module. The power supply is connected with the modulation / demodulation module and is used for supplying power to the modulation / demodulation module.
Description
Technical field [0001] The invention relates to the technical field of UAV power line patrol, in particular to an airborne satellite communication modem used for UAV power line patrol. Background technique [0002] When the UAV power line patrol is performing diversified tasks in the power system, the communication between the carrier aircraft and the command post is an important factor in ensuring the effectiveness of the UAV. The airborne satellite communication modem plays a vital role in an efficient remote communication system. It can ensure the long-distance real-time transmission of voice, data communication, image and video under all-weather conditions, and also improve the aircraft’s ability to operate in complex terrain and weather conditions. An important means of ensuring the ability of wide-area communications. [0003] The airborne satellite communication modem not only needs to meet the requirements of satellite communication data transmission links, but also needs ...
