Problems solved by technology

During the operation of the two, there is a situation where the airborne Beidou short message transceiver interferes with the airborne GPS receiver
However, reducing the transmit power of the antenna may reduce the success rate of sending and receiving short messages. Therefore, the balance between the two needs to be considered when controlling the transmit power.

Abstract

The invention discloses a Beidou short message interference suppression method, a Beidou short message interference suppression device, computer equipment and a storage medium, which are used for controlling the transmitting power of an airborne Beidou short message transceiver antenna so as to avoid interference on an airborne GPS and reduce the influence on the success rate of a short message to the greatest extent. According to the main technical scheme, the method comprises the following steps: acquiring a carrier-to-noise ratio of a GPS satellite signal received by an airborne global positioning system (GPS) receiver; determining whether the carrier-to-noise ratio of the airborne GPS satellite signal is smaller than a carrier-to-noise ratio threshold; and if the carrier-to-noise ratio of the airborne GPS satellite signal is smaller than a carrier-to-noise ratio threshold value, reducing the output power of the airborne Beidou short message transceiver to preset output power.

Description

technical field [0001] The invention relates to the technical field of satellite navigation, in particular to a Beidou short message interference suppression method, device, computer equipment and storage medium. Background technique [0002] The Beidou short message is a characteristic function of the Beidou satellite navigation system. It has the characteristics of two-way communication and can provide global short message communication and regional short message communication. The regional communication capacity reaches 14,000 bits (1,000 Chinese characters) each time, which can transmit text, voice and pictures, and the global communication capacity is 560 bits (40 Chinese characters) each time. This function has important application value for ensuring the safety of civil aviation transportation. [0003] The airborne global positioning system (global positioning system, GPS) antenna and the airborne Beidou short message sending and receiving antenna are installed on t...
