1. An airborne BeiDou system, comprising:
an airborne communication navigation monitoring system into which a BeiDou application software module and a BeiDou protocol stack software module of a BeiDou navigation communication subsystem are integrated;
a BeiDou transceiver connected with the airborne communication navigation monitoring system; and
a BeiDou server connected with the BeiDou transceiver,
wherein
the airborne communication navigation monitoring system comprises a display and control device, and an airborne navigation device with one terminal connected with the display and control device and the other terminal connected with the BeiDou transceiver,
the airborne navigation device is integrated with an Integrated Modular Avionics, and the Integrated Modular Avionics comprises:
a data link application software module interacting with the display and control device, and
a data link communication management module with one terminal connected with the data link application software module and the other terminal connected with the BeiDou transceiver;
the BeiDou application software module is integrated into the data link application software module, and the BeiDou protocol stack software module is integrated into the data link communication management module;
the airborne communication navigation monitoring system is configured to:
receive a user operation instruction, process the user operation instruction based on the integrated BeiDou application software module and BeiDou protocol stack software module to generate a downlink BeiDou short message, comprising: receiving, via the display and control device, the user operation instruction; transmitting, by the display and control device, the user operation instruction to the BeiDou application software module; generating, by the BeiDou application software module, downlink message content for a downlink based on the user operation instruction, and transmitting, by the BeiDou application software module, the downlink message content to the BeiDou protocol stack software module; and processing, by the BeiDou protocol stack software module, the downlink message content to obtain the downlink short message.
