Polyexplore Inc.’s Polynav 2000 Family of top-performing GNSS-aided Inertial Navigation Systems (GNSS/INS) offers a choice of tactical-grade Inertial Measurement Units (IMU), both MEMS and FOG, to meet the challenging performance, as well as the most stringent budgetary requirements.
The Family features a dual-frequency RTK, dual antennas, a Heave measurement for Marine applications, the Distance Measurement Instrument (DMI) assisted dead reckoning for the “urban canyons,” as well as an interface for LiDAR/Radar synchronization and camera triggering for HD mapping applications. The superior centimeter-level positioning and attitude measurement performance of the system combined with an exceptional cost structure.
The Polynav 2000S INS/GNSS features one of the best performing MEMS tactical IMU available. The system delivers superior Attitude and Heading readings, with the Heading accuracy of 0.08° at 1 m baseline as well as Roll and Pitch (RTK) of 0.015°. The dead reckoning feature of the Polynav 2000S allows a low, under 2m over 30-sec, drift during the GNSS outages.
As a member of the Polynav 2000 Family, the system bridges over the MEMS and FOG performances, offering budgetary options for high-precision-minded applications such as HD Mapping, Surveying, and Infrastructure Maintenance.
The Polynav 2000S comes in a ruggedized enclosure with an environmental rating of IP67 for challenging industrial applications. The overall dimensions are 166mm x 134mm x 70mm and weight of ~ 800 g. The OEM version of the system available upon request.
