RTK GNSS/INS

PolyNav 2100H/P

The PolyNav 2100H/P is a high-performance GNSS-aided Inertial Navigation System (INS) family designed and manufactured by PolyExplore. The family has two options:
- Ultrahigh performance “H” version
- High performance “P” version
The system is integrated with triple-frequency multi-constellation GNSS and MEMS IMU. It features tightly coupled GNSS and INS systems and a built-in RTK engine that can achieve centimeter-level accuracy. The PolyNav 2100H/P family is compact and robust. It provides continuously superior performance during GNSS challenged environments and GNSS signal outages using dead-reckoning technique. Furthermore, a distance measurement instrument (DMI), such as an odometer, can be input to the system to provide additional accuracy and reliability. Heave message for marine applications is available.
