DSE Tech GPS TrakPal PDA is a simple to use application providing a full screen graphical interface for data interpreted from a GPS receiver like track data, speed, heading, time, altitude and even acceleration, as well as real time position of the sun and moon to help with lighting up times and after dark travel. Three types of alarms are provided for speed, time and proximity as well as track waypoints. While it has been developed with the car user in mind, it can just as easily be used for sailing, hiking, cycling or other off road activities.
