Das Trägheitsnavigationssystem XY-NAV ist eine leistungsstarke Kombination aus Navigationsprodukten in Industriequalität mit der internen Integration eines dreiachsigen Gyroskops, eines dreiachsigen Beschleunigungsmessers, eines dreiachsigen Magnetometers, eines GPS-Satellitenempfängers, eines barometrischen Höhenmessers und weiterer Sensoren. Die Sensoren wurden für hohe und niedrige Temperaturen kalibriert und die Sensordatenfusion erfolgt über den verbesserten Algorithmus „Erweiterter Kalman-Filter“, der effektiv an Überlastungen, Stöße, Vibrationen, Temperaturschwankungen und andere Umgebungen angepasst ist, um dem Benutzer die höchste Navigationsdatenausgabe von 400 Hz zu bieten.
