FOG INERTIAL NAVIGATION SYSTEM

POLYNAV 2000F

The Polynav 2000 F is an Ultra high-performance, GNSS aided Inertial Navigation System (INS) designed and built by Polynesian Exploration Inc.  

The system features dual frequency RTK with a centimeter-level accuracy, a fiber optics gyro (FOG) based inertial sensor and a compact, robust design. The Polynav 2000 provides superior performance during GNSS signal outages through its tightly coupled GNSS and INS systems. Furthermore, the system is capable of continuously generating highly accurate attitude measurements regardless of whether the platform is moving or static. Also included is a digital quadrature counter, an odometer, which can be used as a distance measurement indicator (DMI) to improve the performance in challenging environments. A Heave message for Marine applications also included.
