2 Description: GPS Module comes with a POT (Patch On Top) ceramic antenna which makes it a small and complete solution for enabling GPS navigation to your embedded devices and robots. It supports 66 Channels and external antenna input compatibility for maximum sensitivity. Module comes with a standard 2mm DIP pin headers which provides easy interface to your device. The module works on TTL Serial protocol which used with any microcontroller or PC. USB cable is included to connect with PC USB port. It can be directly plugged to USB and can be connected to software s like Trimble studio. GPS Module Features Dimension: 16mm x 16mm x 6mm (Full circuit 80mm x 23mm x 12mm) Patch Antenna Size:15mm x 15mm x 4mm Low Power acquisition, tracking L1 Frequency, C/A code, 51-channel High Sensitivity Up to -158 dbm tracking, superior urban performances1 Position Accuracy Without aid: 3m 2D-RMS DGPS(RTM,SBAS(WAAS,EGNOS,MASA)):2.5m 2D-RMS Cold Start is Under 36 seconds (Typical) Warm Start is Under 34 seconds (Typical) Hot Start is Under 1 second (Typical) Data output Baud rate:9600 bps Max. Update Rate:5Hz (Default: 1 Hz) Pin header Connection for easy to assemble USB GPS Module Pin outs GND (Pin1) - Ground VCC (Pin2) - +5V input or if module is connected to USB +5V output TX (Pin3) - This is the UART transmitter of the module. It outputs the GPS information for application. RX (Pin4) - This is the UART receiver of the module. Page 2

4 Arduino Library Tiny GPS is designed to provide most of the NMEA GPS functionality imagine an Arduino user would want position, date, time, altitude, speed and course without the large size that seems to accompany similar bodies of code. To keep resource consumption low, the library avoids any mandatory floating point dependency and ignores all but a few key GPS fields. The sample code included Tiny Gps and Software Serial Library Arduino Program #include <SoftwareSerial.h> #include <TinyGPS.h> /* This sample code demonstrates the normal use of a TinyGPS object. It requires the use of SoftwareSerial, and assumes that you have a 4800-baud serial GPS device hooked up on pins 4(rx) and 3(tx). */ #define rxpin 3 #define txpin 2 TinyGPS gps; SoftwareSerial ss(rxpin, txpin); void setup() Page 4

"); Serial.println(TinyGPS::library_version()); Serial.println(); } void loop() { bool newdata = false; unsigned long chars; unsigned short sentences, failed; // For one second we parse GPS data and report some key values for (unsigned long start = millis(); millis() - start < 1000;) { while (ss.available()) { char c = ss.read(); Page 5

6 // Serial.write(c); // uncomment this line if you want to see the GPS data flowing if (gps.encode(c)) // Did a new valid sentence come in? newdata = true; }} if (newdata) { float flat, flon; unsigned long age; gps.f_get_position(&flat, &flon, &age); Serial.print("LAT="); Serial.print(flat == TinyGPS::GPS_INVALID_F_ANGLE? 0.0 : flat, 6); Serial.print(" LON="); Serial.print(flon == TinyGPS::GPS_INVALID_F_ANGLE? 0.0 : flon, 6); Serial.print(" SAT="); Serial.print(gps.satellites() == TinyGPS::GPS_INVALID_SATELLITES? 0 : gps.satellites()); Page 6
