GPS Localization Algorithm and Software Realization Based on VB

As data between computers and GPS receivers has to be transmitted via RS-232 battery conversion serial ports,it has recently been proposed that VB be employed as a platform for operation,it is proposed that Visual Basic 6.0 and its relevant control functions can be applied to the programming and decoding of the orientation data.This way,the data can be visually accessible and favorable for orientation.By trials and errors,the program for the orientation can correctly decode the data according to NMEA0183 Agreement,calculate and display for the orientation.Conclusively,the program for the orientation is practicable and correct.
