• Basic programming experience with NXC
• Understanding of the GPS coordinate system

1. Construct a way to mount the sensor so that an Ethernet cable can be routed to a sensor port on the NXT
2. Connect an Ethernet cable from the dGPS sensor to a sensor port on the NXT

Here's an example of how to mount the dGPS sensor on the LEGO Tribot

1. Download the dGPS NXC sample programs dgps-nxc-driver.zip
2. Unzip and open up 'DGPS-test1.nxc'
3. Compile and download to the NXT
4. Run the program on your NXT

The dGPS sensor takes a couple minutes to make a GPS connection, even up to 10 minutes on it's first use.

After the dGPS sensor makes a connection, the on-board LED will shine blue and you should have a screen on your NXT that look similar to this:

Final Words

This tutorial's objective was to instruct the reader on how to integrate the dGPS sensor with their LEGO NXT robot.
