RTK GNSS/INS
POLYNAV 2000P/E
The Polynav 2000 P/E is a high-performance, precision GNSS aided Inertial Navigation System (INS) Family designed and built by Polynesian Exploration Inc. The Family comes in two options:
-
An ultrahigh-performance “P” version
-
A budgetary, high-performance “E” version
The system features dual-frequency RTK with a centimeter-level accuracy and compact, robust design. The Polynav 2000P/E Family 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 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.
