GPS Button 1.1 - GPS provides position information, 24 hours a day in any kind of weather, anyplace in the world; the GPS position signals are available at no charge for consumer and commercial use. The satellites which compromise the GPS system were developed by the U.S. Department of Defense (DoD) and launched by the U.S. Air Force. GPSButton is a floating button which allows your Newton to place a copy of your current position obtained from a Trimble Navigation GPS Scoutmaster product anywhere you can write or type. Let's you quickly and easily annotate any Newton application's data with their current position. Requires a Trimble ScoutMaster GPS receiver.
