Chao Zhang · Gnss World of China · 2014
The USA National Marine Electronics Association developed a set of universal ASCII DATA Format,the NMEA protocol for the establishment of a unified RTCM navigation device(RTCM)standard in GPS(Global Positioning System).At present a lot of wireless communications equipment interface and communication protocol according to the format of NMEA-0183.By studing on ASCII serial communication in the real-time data stream format and the method of resolving real time data,and,writing the program of the method on the platform of VC++2008,this paper can povide some help for the accurate real time data acquisition in satellite navigation and positioning.
