 ==== 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.

 ==== Sample program with the dGPS API ====
-  - Download the dGPS NXC driver {{:alvarop:dgps-nxc-driver.zip|}}
+  - 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 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: {{:dgps_sample_program_output.jpg?500|}}
+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.

 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.
