Study And Design Of GPS ReceiverLab System Based On LabVIEW

With the development of wireless information technology,the demand for wireless communication is increasing.Wireless communication technology has a broad development platform,based on its communication in anytime and anywhere,which bring great convenience to people's work and life.GPS technology,as one of the newest technology in military,communications,exploration,navigation,is widely used in people's daily life.Positioning service has entered the common people life and become indispensably.To get rid of the rely on GPS system,China is developing the independent innovation of the BeiDou Navigation Satellite system(BDS).The paper focuses on using LabVIEW to design a GPS receiver.In this paper,the GPS satellite positioning system is introduced in detail,the NMEA-0183 protocol of GPS receiving data is analyzed,and the algorithm is used to analyze the GPS original information through Arduino environment.In addition,this paper introduced the graphical programming environment of LabVIEW,and used LabVIEW environment design algorithm to analyze GPS data,design the upper computer and realize the wireless communication between upper and lower computer.This paper relies on Arduino UNO hardware to design a simple and widely used wireless location system that will be used in everyday life.PC using Baidu map API interface to achieve the location of the map,the wireless positioning system using Bluetooth technology and wireless communication between the host computer to achieve the purpose of real-time Map location.This paper completed the hardware and software design of the system and passed the test.This design achieved the expected precise positioning effect.The research conclusions and innovations in this paper are that the first is to successfully extract positioning information such as Standard time,latitude and longitude,and the use of a TFT liquid crystal display to display the resolved positioning information to implement the hardware design of the GPS mobile positioning system.After the GPS mobile positioning system is tested,the positioning speed is fast and the positioning is accurate,and the expected results are achieved.The second is to introduce the method of WebBrowser function accessing Baidu API in LabVIEW,use API interface to complete coordinate conversion,and introduce static map.The third is to design and use UART communication protocol to achieve one-way communication between GPS terminals,ArduinoUNO,and PC terminals,and achieve the goal of real-time monitoring and mobile systems on the PC side.
