Prototype of the new Honeywell GPS-aided MEMS based navigation system (GPAHRS) has been validated through a large flight-test campaign performed under the Clean Sky 2 Large Passenger Aircraft (LPA) Platform 3 project. The campaign itself (more than 200 flight hours in total) was focused on the business jets (Dassault Falcon 900EX), commercial jets (Airbus A330), and regional aircrafts and various flight test scenarios. This paper provides an overview of the GPAHRS system itself, its integration within the Flight Test Bed (FTB) equipment, and most importantly, performance (in terms of accuracy and integrity) validation of results obtained during the campaign.
