CONFIGURATION:

3.1 TOOLS DETAILS:

U‐Center is the tool used here for tes�ng.

[Note: Please find evalua�on tool in the below link

http://www.u-blox.com/en/evaluation-tools-a-software/u-center/u-center.html ]

TESTING PROCEDURE :

v Make sure that you have followed the connec�ons as described in

sec�on 2.2 before the power up the device.

v Power up the module with 12V supply.

v Two LED's (LED2 and LED3) will glow constantly un�l the GPS get

fixed.

v As soon as GPS fixed LED2 starts blinking for every 1sec interval and

LED3 will glow con�nuously (power up LED).

v Open tool and set the port number (image1) and baud rate (9600Kbps

default image2).

v Open text console where data to be observed in the workbench by press‐

ing F8 or selec�ng text console in view op�on on the toolbar as shown in

the image below.




v Ini�ally as soon as the device powered up GPS receiver search for the

satellite by displaying NMEA data as shown in image below. (Shown in

arrow).

[Note: Right side indicates the number of satellites and its strength and also

other details available in tracking]

v When posi�on of the system in tracked the data will be displayed in NMEA

format as shown in image below.




4.1 OUTPUT DATA FORMAT :

Output obtained should be in NMEA format (82 character format) as shown

below.

Syntax :

$ Address field *<cr><if>

$ ‐ Start character.

Address field ‐ contains talker id (that iden�fies a GPS receiver) and mes‐

sage iden�fier (contains various data field separated by ',' character).

* ‐ indicates start of checksum.

<cr> ‐ carriage return.

<Lf> ‐ line feed sequence (end character).

Example:

1 ‐ Global Posi�oning System Fix Data.

2 ‐ Universal Time Coordinated (UTC).

3 ‐ Status A=ac�ve

4 ‐ La�tude

5 ‐ N‐north S‐south

6 ‐ Longitude

7 ‐ E‐east W‐west

8 ‐ Speed over the ground in knots

9 ‐ Track angle in degrees

9 ‐ Horizontal dilu�on of precision

10 ‐ Date and year

11 ‐ Magne�c varia�on

12 ‐ The checksum data
