Inertial Labs INS-BU GPS-Aided INS

Inertial Labs INS-BU Single Antenna INS

Manufacturer: | Categories: ,

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



The INS-BU single antenna INS 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, single antenna U-Blox GNSS receiver that provides 1 cm RTK position from RTCM3 RTK corrections and supports a wide range of GNSS constellations.

Unlike other solutions available, the INS-BU comes right off the shelf with full access to all major constellations and frequencies: GPS L1/L2, GLONASS L1/L2, Galileo E1/E5, BeiDou B1/B2 and QZSS L1/L2. Designed for UAVs, land vehicles and marine Vessels, the INS-BU is an effective, low-cost solution that uses a range of aiding data for different applications. With highly accurate navigation in GNSS-denied environments (utilizing the enhanced tunnel guide algorithm), the INS-BU delivers a comprehensive GNSS-denied solution at a price point that is unmatched.

One of the key elements to the success of the INS-BU 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. The 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-BU provides a full navigation solution for both GNSS and GNSS-denied environments at an unparalleled value. With custom interfaces and a power consumption of two and a half Watts, the INS-BU is a versatile solution fit for a wide variety of users with power consumption restrictions. In addition, the INS-BU contains our on-board sensor fusion filter, state of the art navigation, and guidance algorithms and calibration software. The on-board ZED-F9P receiver ensures the security of positioning and navigation information by using secure interfaces and advanced jamming and spoofing detection technologies.
