Initial Realization of a Sensor Fusion Based Onboard Maritime Integrated PNT Unit

Abstract

This paper introduces the basic concept of the Position Navigation and Timing (PNT) Module as future part of a ship side Integrated Navigation System (INS). Core of the PNT Module is a sensor fusion based processing system (PNT Unit). The paper will focus on important aspects and first results of the initial practical realization of such a PNT Unit, including a realization of a Consistent Common Reference System (CCRS), GNSS/IMU tightly coupled positioning results as well as contingency performance of the inertial sensors.
