PolyExplore, Inc. POLYNAV 2000S

Polynav 2000S MEMS RTK INS/GNSS offers superior, near-FOG performance at MEMS price

The Polynav 2000S is a superior, near FOG -performance GNSS aided MEMS-based Inertial Navigation System (INS) by PolyExplore Inc. The system offers dual antennas for precision heading and a dual-frequency RTK support that provides centimetre-level accuracy with fast conversion time and superior performance during GNSS signal outages through its tightly coupled GNSS and INS systems. The Polynav 2000S supports a fusion of odometer inputs as well as heave estimation for marine applications.

Description

The Polyexplore Inc.’ Polynav 2000 Family of the top-performing GNSS aided Inertial Navigation Systems (GNSS/INS) offers a choice of the 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.
