GNSS-Aided Inertial Navigation Systems (INS)

PolyNav 2000H/P – dual frequency RTK GNSS-INS

PolyNav 2000HP RTK GNSS-INS for UAVThe PolyNav 2000H/P high-precision GNSS-aided Inertial Navigation System (INS) leverages the advantages of both GNSS and INS to provide centimeter-level position and velocity measurement accuracy for UAVs and other unmanned vehicles. The system offers dual frequency Real Time Kinematic (RTK) positioning and tightly-coupled GNSS and INS systems to provide superior performance even during GNSS signal outages.

The system continuously generates highly accurate attitude measurements whether the platform is moving or static, and is highly effective even in urban environments. Automotive Dead Reckoning (ADR) technology maintains position for up to 30 seconds during GNSS outages that may occur under bridges or inside tunnels, making the PolyNav 2000H/P ideal for autonomous driving applications.

The PolyNav 2000H/P offers a choice of three grades of inertial sensor performance:

  • Ultrahigh-performance “H” version
  • High-performance “P” version
  • Budgetary, high-performance “E” version.

The system is packaged in a ruggedized 145mm x 120 mm x 45mm enclosure, and features CAN, Ethernet and USB interfaces, 2 UARTs, and one PPS output.
