Abstract

The embodiment of the invention discloses a communication terminal for a high dynamic carrier. The communication terminal comprises an antenna module, a short message baseband processing module, a short message power amplifier module and a short message radio frequency receiving module. The communication terminal is equipped with a forward and backward signal processing process. The forward signal processing process comprises the step that after a signal of a GEO satellite is received by the antenna module, the signal is processed by the short message radio frequency receiving module and the short message baseband processing module in sequence and then is transmitted to an airborne computer of the high dynamic carrier. The backward signal processing process comprises the step that telemetering data is received by the airborne computer of the high dynamic carrier, the telemetering data is processed by the short message baseband processing module and the short message power amplifier module in sequence and then is sent to the GEO satellite through the antenna module. According to the communication terminal, reliable communication of the high dynamic carrier can be realized.

Description

technical field [0001] The invention relates to the communication field, in particular to a communication terminal for high dynamic carriers. Background technique [0002] The short message function is a technological breakthrough unique to the Beidou system and not available to GPS. Based on the short message function, it can conduct two-way communication with the Beidou positioning main station, while GPS can only perform one-way communication. It can be widely used in situations where ordinary mobile communication signals cannot cover, such as oceans, deserts and the wild. In these harsh environments, short messages can be used for emergency communication. [0003] For high-dynamic carriers such as spacecraft, aircraft, and missiles, when the motion speed is high, due to the existence of the Doppler effect, it will bring considerable difficulties to the signal processing of the communication link, resulting in a sharp decline in communication quality and communication eff...
