+==== dGPS for LEGO NXT ====
+The Dexter Industries GPS is a GPS unit manufactured for use with the LEGO® MINDSTORMS® NXT. The sensor calculates positional and navigational data. It then delivers latitude, longitude, time, velocity, angle of travel, and navigational information such as distance and angle to a specified destination. The dGPS can be accurate up to 3 meters as most civilian GPS sensors are. Below is a diagram for the dGPS sensor and a table of percent difference calculations to a modern smartphone.

+==== Installing the dGPS Sensor on Your LEGO NXT Robot ====
+  - Construct a way to mount the sensor so that an Ethernet cable can be routed to a sensor port on the NXT
+  - 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

+==== Sample program with the dGPS API ====
+  - Download the dGPS NXC sample programs {{:alvarop:dgps-test1.7z|}}
+  - Unzip and open up 'DGPS-test1.nxc'
+  - Compile and download to the NXT
+  - Run the program on your NXT
+The dGPS sensor takes a couple minutes to find a satellite signal, even up to 10 minutes on it's first use.
+Before a signal is acquired, the GPS will begin sending the default location and time (121000000 E, 24000000 W) until a valid signal is locked by the sensor.
+After the dGPS sensor finds a satellite signal, 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.
+The sample program has all the sensor functions and how they should be implemented into a program. From there one can integrate them into their own program.
