INS-DU - Low-cost Dual Antenna Inertial Navigation System
Available from Inertial Labs Inc
INS-DU is a high performance system that determines position, velocity, and absolute orientation to any platform that it is mounted to. It utilizes a dual antenna u-blox GNSS receiver that provides 1 cm RTK position from RTCM3 RTK corrections and supports a wide range of GNSS constellations. 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, INS-DU delivers a comprehensive GNSS-denied solution at a significantly lower price point.
One of the key elements to the success of the INS-DU is its use of the miniAHRS, which utilizes 3-axes 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.
INS-DU provides a full navigation solution for both GNSS and GNSS-denied environments at an unparalleled value. With custom interfaces and a power consumption of 2.5 Watts, INS-DU is a versatile solution fit for a wide variety of users with power consumption restrictions. In addition, INS-DU contains our on-board sensor fusion filter, state of the art navigation, and guidance algorithms and calibration software.
