GNSS Compass

The GNSS Compass is a low cost all in one GNSS/INS navigation and heading solution. It provides accurate dual antenna GPS based heading that is not subject to magnetic interference and can maintain accurate heading during GNSS outages of up to 20 minutes. It features high accuracy RTK positioning and is plug and play with NMEA 0183, NMEA 2000 and Ethernet interfaces.

Features

Fully Integrated Navigation
Fully Integrated Navigation
The GNSS Compass is a fully integrated wheelmark certified GPS/INS navigation and heading solution. It contains a 9 axis IMU that is integrated with a dual antenna GNSS system with high performance antennas. It provides higher heading accuracy than magnetic systems and does not require any calibration or setup. The system is plug and play for NMEA 0183 and NMEA 2000 integrations, requiring no setup or configuration.
Performance and Interface Options
Performance and Interface Options
Four product variants are available to cater to every different application and budget. The low cost variant is an L1 only solution that is suitable for commercial vessel navigation while an L1/L2 variant meets the high accuracy requirements of surveying applications. It is also possible to choose between an NMEA 0183/NMEA 2000 interface and a Power over Ethernet interface for maximum flexibility. The Ethernet variant features NTP and PTP timing servers for precise time synchronization.
High Accuracy 8mm Positioning
High Accuracy 8mm Positioning
The high accuracy variant supports L1/L2 RTK to deliver real time position accuracy of 8mm. Both the high accuracy and low 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.
Minimized Size, Weight and Price
Minimized Size, Weight and Price
The GNSS Compass dramatically reduces the size weight and cost of attaining a high accuracy position and heading solution. In addition the plug and play functionality of the device means that anyone can install it in minutes.

Applications

Marine
Marine
The GNSS Compass is ideal for all sorts of marine applications including racing yachts, commercial container vessels and recreational vessels. It features plug and play operation for NMEA0183 and NMEA2000 networks. It is a wheelmark certified satellite compass for use on commercial vessels.
Automotive
Automotive
The GNSS Compass is a convenient option for high accuracy position, velocity, roll, pitch and heading on ground vehicles. It can be installed in minutes 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. It is also a very valuable navigation sensor suite for autonomous vehicles.
Marine Surveying
Marine Surveying
For applications such as USBL underwater positioning, side-scan sonar, LBL and other marine surveying technologies the GNSS Compass brings performance at a revolutionary price. The plug and play operation allows for fast and easy setup. Advanced Navigation's Kinematica post-processing suite allows the data to be further enhanced after the survey.
Antenna Targeting
Antenna Targeting
The GNSS Compass is an easy and low cost addition for high accuracy roll, pitch and heading in both stationary and dynamic antenna targeting applications.
