RTK GNSS/INS
POLYNAV 2000P OEM
The Polynav 2000P OEM GNSS-Inertial System is a high-performance high-precision GNSS aided Inertial Navigation System (INS) designed and built by Polynesian Exploration Inc. This system offers dual frequency RTK that provides centimeter level accuracy while also providing 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. The Automotive Dead Reckoning (ADR) solution provided by Polynav 2000P OEM delivers strong performance in challenging environments such as cities.
FEATURES
