MEMS RTK GNSS/INS
POLYNAV 2000H/P
The Polynav 2000H/P is a high-performance, precision GNSS aided Inertial Navigation System (INS) Family designed and built by Polynesian Exploration Inc. The Family comes in three options:
-
Ultrahigh-performance “H” version
-
High-performance “P” version
The system features dual-frequency RTK with a centimeter-level accuracy and compact, robust design. The Polynav 2000H/P 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.
FEATURES
• Centimeter level positioning with highly accurate attitude and heading whether the platform is static or moving
• High accuracy velocity, acceleration, attitude (Roll, pitch, heading), and angular rate
• GPS, GLONASS, Beidou, Galileo*, and SBAS
• Dual frequency (L1 & L2) RTK
• Global PPP
• Dual antenna for accurate heading
• Best in class price-performance ratio
• 100 Hz navigation solution and the raw measurement output
• Tactical grade solid-state IMU sensor
• Multiple sensor fusion
• ROS driver ready
• Heave message
