Inertial Labs INS-DU Dual Antenna

Inertial Labs INS-DU Dual Antenna INS

Manufacturer: | Categories: ,

The INS-DU from Inertial Labs is a U-Blox based, low-cost GPS-Aided Inertial Navigation System with accurate positioning and dual antenna heading. It delivers high accuracy RTK position for air, land and marine applications.



The INS-DU Dual Antenna from Inertial Labs is a high performance strapdown system that determines position, velocity and absolute orientation to any platform that it is mounted to. It utilizes a cost-effective, dual antenna U-Blox GNSS receiver that provides 1 cm RTK position from RTCM 3 RTK corrections and supports a wide range of GNSS constellations.

Designed for UAVs, land vehicles and marine vessels, the INS-DU is an effective, low-cost solution that uses a range of aiding data for different applications. With highly accurate navigation in GNSS-denied environments, the INS-DU delivers a comprehensive GNSS-denied solution at a significantly lower price point.

One of the key elements of the INS-DU is its use of the miniAHRS, which utilizes 3-axis each of precision magnetometers, accelerometers and gyroscopes to provide orientation of the device under measure. It contains cutting-edge algorithms for the motion of robots, unmanned and autonomous vehicles and antennas. MiniAHRS mini fluxgate magnetometers have a distinct advantage over commonly used magneto-inductive or magneto-resistive alternatives and have been a trusted North reference for over 70 years.

The INS-DU provides a full navigation solution for both GNSS and GNSS-denied environments at an unparalleled value. With custom interfaces, the INS-DU is a versatile solution fit for a wide variety of users.
