Video of module 

TinyGPS++ is a new Arduino library for parsing NMEA data streams provided by GPS modules.
Like its predecessor, TinyGPS, this library provides compact and easy-to-use methods for extracting position, date, time, altitude, speed, and course from consumer GPS devices. 
However, TinyGPS++’s programmer interface is considerably simpler to use than TinyGPS, and the new library can extract arbitrary data from any of the myriad NMEA sentences out there, even proprietary ones.
Download the Arduino source code from here 
To install this library, download here, unzip the archive into the Arduino “libraries” folder, and restart Arduino. You should rename the folder “TinyGPSPlus”.

 

Qt-based car GPS monitoring system (6) GPS information processing

GPS Module (NEO-6M UBLOX)

GPS module through tiny6410 development board with the serial port to connect to the development board to pass GPS positioning information (NMEA-0183 protocol).

 

Introduction to the NMEA-0183 protocol

NMEA 0183 is the National Marine Electronics Association (National Marine Electronics Association) for the marine electronic equipment to develop the standard format. Has now become a GPS navigation equipment unified RTCM (Radio Technical Commission for Maritime services) standard protocol.

NMEA-0183 protocol uses ASCII code to transfer GPS positioning information, we call the frame.

$ GPRMC (Recommended Minimum Specific GPS / Transit Data)

The basic format GPRMC statement is as follows: GPRMC, (1), ( 2), (3), (4), (5), (6), (7), (8), (9), (10), ( 11), (12) * hh (CR) (LF)

E.g: 
$ GPRMC, 033308.00, A, 3022.29739, N, 11454.04296, E, 0.044, 111116 ,,, A * 75

(1) UTC time, hhmmss (hours and seconds) 
(2) positioning state, A = effective positioning, V = invalid positioning 
(3) latitude ddmm.mmmmm (degrees) 
(4) latitude hemisphere N (northern hemisphere) or S (southern hemisphere) 
(5) longitude dddmm.mmmmm (degrees) 
(6) longitude hemisphere E (longitude) or W (west longitude) 
(7) The ground speed (000.0 to 999.9) 
(8) ground heading (000.0 ~ 359.9 degrees, with true north as the reference) 
(9) UTC date, ddmmyy (day month month) 
(10) magnetic declination (000.0 ~ 180.0 degrees, less than the leading digits complement 0) 
(11) Magnetic declination direction, E (east) or W (west) 
(12) Mode indication (A = autonomous positioning, D = differential, E = estimation, N = data invalid)

The serial port receives GPS complete data
