INS-DU Dual Antenna

INS-DU – Dual Antenna, GPS-Aided Inertial Navigation System

Inertial Labs Releases U-Blox Based, Low-Cost GPS-Aided Inertial Navigation System, INS-DU with Accurate Positioning and Dual Antenna Heading.

Precision in navigation is not just a requirement but the backbone of modern transportation, autonomous vehicles, and high-stakes applications where every millimeter and millisecond counts. The INS-DU represents a quantum leap in this precise science, combining the advanced capabilities of a dual-antenna setup with the reliability of GPS-aided inertial navigation. We are exploring the intricacies of the INS-DU system, showcasing how it leverages the synergy between its antennas and sophisticated algorithms to deliver unparalleled accuracy and reliability. From unmanned aerial vehicles soaring through chaotic skies to automated machinery operating in obstructed fields, the INS-DU stands as a beacon of navigational excellence. Let’s delve into the world of advanced orientation and positioning that the INS-DU makes both possible and exemplary. The new INS-DU delivers high-accuracy RTK position for Air, Land, and Marine Applications.

Paeonian Springs, VA: The new INS-DU 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 a 1 cm RTK position from RTCM3 RTK corrections and supports a wide range of GNSS constellations. Designed for UAVs, Land Vehicles, and Marine Vessels, the INS-DU is a practical, low-cost solution that uses various 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 critical elements to the INS-DU’s success is its miniAHRS, which utilizes 3-axes of precision magnetometers, accelerometers, and gyroscopes to provide an orientation of the device under the 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 complete 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-DU is a versatile solution for many users with power consumption restrictions. In addition, the INS-DU contains our onboard sensor fusion filter, state-of-the-art navigation, guidance algorithms, and calibration software.

Inertial Labs, already the leader in position and orientation sensor technologies, is growing its catalog of innovative solutions at the best value, smallest size, and lowest power consumption. From commerce and industry to government, defense, and aerospace, Inertial Labs is at the forefront of developing and customizing products for exciting technologies, solving today’s problems, and unraveling those of tomorrow.
