The new GPS III is the result of a consistent further development of the GPS II, which has been on the market for over eight years. A complete restructuring of the software has significantly improved performance and introduced new features. The GPS III automatically recognizes which remote control system or PowerBox/iGyro it is connected to and sets up communication completely automatically. Using the PowerBox terminal, various slots can be selected for Futaba. For HoTT and Multiplex, different alarms can be set for altitude or distance. The GPS III can display additional information for most systems, such as the number of satellites, accuracy of position data, and 2D distance. The proven Helix radial antenna has been carried over from the GPS II – the unique feature of the PowerBox GPS: it ensures GPS reception in all flight attitudes.
