Jeon, Sanghoon, So, Hyoungmin, No, Heekwon, Lee, Taikjin, Kee, Changdon, 'Development of Real-Time Software GPS Receiver using Windows Visual C++ and USB RF Front-end,' Proceedings of the 2010 International Technical Meeting of The Institute of Navigation, San Diego, CA, January 2010, pp. Proceedings of the 2010 International Technical Meeting of The Institute of Navigation Positioning result of software receiver is similarĭistribution compared with that of commercial receivers. Test has been accomplished in 30 minutes and the Roof-mounted antenna with two commercial receivers.

This software has been tested using GPS live data from Same vein, saved code/carrier replica tables are used for Phase correlations and accumulations are computed byīit-wise parallel techniques and 16 bit sum table. Reduce repetitive computation, in-phase and quadrature Correlator in this threadĮspecially needs lots of computation because of mass baseband data (16.376Mbps) from USB RF sampler. Of signal processing including acquisition, tracking, and In signal processing thread, whole stages Thread contains displaying receiver status and receiving Saving down-converted IF data stream to data buffer. USB Data Control threadĬontains USB configuration, data stream control and Interface) & display of receiver status thread and signal Threads which are USB control thread, GUI (Graphic User The real time software GPS receiver is composed of three (General Public License) USB library is used for USB Kernel Library for FFT calculation and MFC (Microsoftįoundation Class library) for multi-threads and data The software receiver isĭeveloped using Visual C++ 2008 program tool on IF (Intermediate Frequency) data is collected from SiGe

It isĪlso flexible for new GNSS signal policy and forĭevelopment of sensor integration system. On a PC with Linux Mint Ive installed Windows 10.

Or DSP (Digital signal processor) and provides moreĬomfortable debugging environment of commercialĭevelopment tools than that of embedded system. DNRGPS and its predecessor were built to transfer data between Garmin handheld GPS receivers and GIS software. Processing than FPGA (Field-Programmable Gate Array) General purpose computer is able to deal with larger data Real-time PC-based software GPS receiver.
