RTK GNSS/INS
POLYNAV 2000S
The PolyNav 2000S is a top of the line ultra-high-performance, GNSS aided MEMS Inertial Navigation System (INS) designed and built by PolyExplore Inc. The quad-constellation, dual antenna system features dual-frequency RTK with a centimeter-level accuracy and compact, robust design.
The PolyNav 2000S provides near FOG performance and ideal for such applications as HD Mapping, Bathymetry, Autonomous Driving, and many more. The system provides superior performance during GNSS signal outages through tightly coupled GNSS and INS systems as well as digital quadrature counter when used as a distance measurement indicator (DMI). Furthermore, the PolyNav 2000S is capable of continuously generating highly accurate attitude measurements regardless of whether the platform is moving or static. The system can output an internal PPS signal and timestamps even in the absence of the GPS signal. A Heave message for the Marine applications is available.
FEATURES
