AD Navigation employs a team of uncompromising professionals, all of whom have a passion for high-tech navigation. The company was founded in 2002, in Sarpsborg, Norway by Lorentz Ryan. Our innovative products quickly caught on with some major clients, and in 2005 we joined the HITT Group of companies (now SAAB Group). The AD Navigation AS headquarters is located near the harbour in Tønsberg, Norway, where we have our development lab, as well as a live lab on local ferries for testing purposes. Through a fruitful cooperation with key customers, we have over the years developed and supplied state-of-the-art products mainly within hydrography and dredging positioning applications as well as for portable navigation systems for pilots.
