The Advanced Navigation Global Navigation Satellite System (GNSS) receiver is a fully integrated, certified
navigation and heading solution. It provides high accuracy position, velocity and heading information and
does not require any calibrations or setup. It can provide accurate heading even during GNSS outages (for
up to 20 minutes). This is possible as a result of the INS (Inertial Navigation System) integration in the unit.
The antenna is equipped with two internal GNNS receivers and its heading is not subject to magnetic
interference.
The vessel doesn’t have to move to provide an accurate heading.
The built-in PTP (Precision Time Protocol) server provides an accurate timing reference for the whole
system.
The GNSS is powered through the Ethernet cable.
For more details on the GNSS Sensor itself, please refer to the User Manual, as available on: the Advanced
