Resign And Implementation Of Beidou Navigation Terminal Test Software

The position,speed and time information provided by the Beidou two generation navigation system(BeiDou Navigation Satellite System,BD2)can be used in many applications in our daily life.China's development of the positioning system compared with the United States later.Until 2013,China inclined geosynchronous orbits 5 satellites,4 satellites in earth orbit,geostationary orbit 5 satellites,in normal operation,are referred to as IGSO,MEO,GEO satellite satellite satellite.For China's military and civilian users to provide positioning,group user management and precision time service.Whether in the civil field,or in the military market,in the process of phased growth and improvement,the application frequency of the Beidou terminal are constantly improving.Many terminal manufacturers also like bamboo shoots after a spring rain like emerge,military and industrial applications of the Beidou equipment to enter the market.Firstly,this paper summarizes the principle of terminal equipment and the key technology of developing test software.Terminal design most is to use the software to form beidou receiver,because this method can completely from the traditional way of hardware,to a more flexible processing data collected in the various types of hardware,in terms of digital signal processing,software can almost think that is not restricted by hardware.Then,the demand for Beidou satellite terminal is analyzed,design a special test software to evaluate the real state of the terminal more accurately from the aspects of performance,function and so on.This paper summarizes the concept of navigation system and terminal and the related theory involved in order to achieve its various types of Beidou models in a unified platform for functional and performance testing as the goal,in order to achieve this purpose,the need for serial communication Technology,satellite positioning data related to the conversion calculation.Through the analysis of the information received by the terminal,based on the actual test needs,the test data for exploratory research.This study discusses the implementation of the software from three aspects: theory,practice and testing.
