Design And Implementation Of The Beidou Dual Model Receiver Applied In Airborne Navigation

Beidou satellite navigation system is the infrastructure of China's military and civilian construction, which promotes the construction and development of all aspects of the country. Compass has the characteristics of autonomy, openness and short message, which provides a new direction for the development of airborne navigation.At present, satellite navigation has been widely used in all aspects of airborne navigation because of its high precision, real-time positioning, and no accumulated error. Among these, the product that relies on GPS application is the most. However, the location of the information submitted, it is required to spread through the radio communication. The disadvantage of this approach is that the communication base station relies on a large degree. By using the characteristics of the Beidou short message, it can realize the satellite communication and get rid of the dependence on the base station.Through the combination of Beidou satellite navigation system Beidou short message function and Beidou two generation high precision positioning function, use the autonomy and security advantages in Beidou Beidou double and two generation model of the receiver application, has the very high value in the field of airborne navigation.The following work is done by the author in this paper:(1) the realization of the hardware design of Beidou double model receiver, including RF circuit, baseband processing circuit, power supply circuit design system; by improving the design of the comparator, improve the system consistency of manufacturing; complete the design and Simulation of circuit board PCB. And complete the test of the receiver;(2) the design and implementation of the system based on the Beidou double model receiver, which is applied to the airborne mission, and has completed the test of the system and achieved satisfactory results;(3) research on the Beidou satellite navigation and positioning system and the satellite navigation receiver architecture, and complete the analysis of the positioning performance of the Beidou RDSS and RNSS can be achieved and come to a conclusion.Finally, this paper realizes the design of the Beidou double model receiver, and based on the application of airborne navigation, this paper presents a system scheme. The experimental results show that the system is stable and reliable, and meets the use of airborne navigation. Through the research of this paper, promote the research and development of the related field of the compass.
