The sensor provides latitude, longitude, time, speed and heading to your robot. It also has powerful navigational calculators that can be used to navigate to target coordinates.
The Dexter Industries GPS Sensor can be used for any robot that needs to know where it is or where it’s going. You can do everything from track road trips on Google Maps to build a satellite-guided robot.
The dGPS hooks directly into any of the four sensor ports on the NXT and can be programmed in NXT-G, RobotC, and Lejos.
