Advanced Navigation has recently announced the release of the company’s GNSS Compass all-in-one GNSS/INS navigation and heading solution. The GNSS Compass provides accurate heading, position and velocity, and can maintain accurate heading even during GNSS outages (for up to 20 minutes). This is possible as a result of the INS integration embedded into the product. The GNSS Compass is also not subject to magnetic interference.
The GNSS Compass is suitable for marine robotics applications, such as unmanned surface vessels (USVs), and is wheelmark certified for use on commercial marine vessels meeting the required standards of safety and performance across the EU. The system is also ideal for navigation of land-based autonomous vehicles, and does not have any motion requirements to achieve its heading accuracy like other GPS/INS systems, which makes it suitable for slow moving survey vehicles.
The plug and play unit contains a 9 axis IMU that is integrated with a dual antenna GNSS system with high performance antennas, and features NMEA0183, NMEA2000 and Ethernet interface options.
Four product variants are available. The high accuracy variant supports L1/L2 RTK to deliver real time position accuracy of 8mm. Both the high accuracy and lower cost variant support PPK (post processing) to deliver 8mm position accuracy using the Kinematica post processing software. Both variants support all of the current and future satellite navigation systems including GPS, GLONASS, GALILEO and BeiDou.
