Working with a GPS module for navigation

GPS is module that receives a certain location from a satellite. GPS is a good method for finding a location when outdoors. Several GPS satellites can be used in the GPS module.

In this section, we will try to access a location from a GPS module. Location information obtained from the satellite will be sent to a computer through Bluetooth.

We will use the U-blox NEO-6M Module to retrieve the location from the satellite. We will use the same Bluetooth module, HC-06, in this demo. A computer will listen to the GPS data from a robot. The GPS data that are sent are latitude and longitude coordinates.

I obtained a U-blox NEO-6M from dx.com (http://www.dx.com/p/gps-module-w-ceramic-passive-antenna-for-raspberry-pi-arduino-red-384916). This module is cheap, and you can buy it on Banggood, eBay and AliExpress.

A form of U-blox NEO-6M module is shown in the following figure:

U-blox NEO-6M Module provides TTL output so we can access the data easily. GPS data from...
