The new single-body Polynav2000F RTK INS/GNSS, by Polynesian Exploration Inc, offers superior performance in HD mapping, surveying, and marine applications

The Polynav2000F is a high-performance GNSS aided fiber optics gyroscope (FOG) based Inertial Navigation System (INS) designed and built by Polynesian Exploration Inc. The System offers dual antennas for precision heading and a dual frequency RTK support that provides centimeter level accuracy with fast conversion time while maintaining a superior performance during GNSS signal outages through its tightly coupled GNSS and INS systems. The Polynav2000F supports such features as fusion of odometer inputs for urban navigation and mapping, as well as heave estimation for marine applications.

The Polynav 2000F high-performance FOG INS/GNSS features Heave measurement for Marine applications, Distance measurement input (DMI) assisted dead reckoning for urban canyons, tunnels, and under bridges driving environment, as well as a rich interface for multi LiDAR/Radar synchronization and camera triggering for HD mapping applications.  The superior performance of the system is combined with an exceptional cost structure.

The new single body Polynav2000F is a follow-up on a top-rated GNSS/INS product with an ultra-high-performance inertial measurement unit (IMU) with a fiber optic gyroscopic rate sensors (FOG) and a standalone GNSS rover station. The single body unit provides further enhancement by providing a compact, ruggedized enclosure with a “rigid body” platform for both, an IMU and a rover. That will simplify set up and design-in time for multiple applications which do not require separate placement of a rover and an IMU.

Overall, the Polynav 2000F Family offers multiple options for varieties of applications. The ruggedized rover and stand-alone FOG IMU configuration are well suited for the bigger marine autonomous and surveying vessels, construction and agricultural equipment, as well as commercial tracks. The aerial fixed-wing HD mapping and surveying applications addressed with GNSS OEM module weighing under 70 g, and stand-alone IMU.

The Polynav2000F Family fully utilizes the advantages of precision GNSS and FOG inertial measurement unit (IMU) as a tightly coupled inertial navigation systems (INS) to provide centimeter-level position and velocity measurement accuracy with dual frequency Real Time Kinematic (RTK), together with less than 0.01-degree accuracy attitude measurements. The dual antennas provide superior short-term stability against outages and highly accurate heading in dynamic or static positions. The odometer input provides for even tighter coupling and support during the GNSS outages. The marine applications supported by heave measurements.
