INS-U, a GPS-Aided Inertial Navigation System

Learn about the new INS-U, GPS-Aided, and fully integrated INS, Attitude & Heading Reference System (AHRS), Inertial Measurement Unit (IMU), and ADC high-performance strapdown system that determines position, navigation, and timing (PNT) information for any device on which it is mounted.

Paeonian Springs, VA: Part of Inertial Labs’ new generation of GPS-Aided INS solutions, the INS-U utilizes a single antenna, multi-constellation U-Blox GNSS receiver. With access to GPS, GLONASS, Galileo, QZSS, and BeiDou, the INS-U can be used in various GPS-enabled environments and is protected against spoofing and jamming. The INS-U comprises two barometers, a miniature gyro-compensated fluxgate compass, and tri-axis temperature-calibrated advanced MEMS accelerometers and gyroscopes. These high-performance sensors and Inertial Labs’ new onboard sensor fusion filter, state-of-the-art guidance, and navigation algorithms provide the device’s accurate position, velocity, and orientation under measure.

Perhaps the most defining feature of the INS-U is its embedded ADC. An essential avionics component for modern UAV applications, an ADC outputs static & dynamic pressure, pressure altitude, calibrated & true airspeed, actual angle of attack, rate of climb, and wind speed of the device under measure. Combined with inertial reference information, this data provides UAVs with accurate information about the unit and its relation to its environment.

By utilizing data from INS, AHRS, IMU, and ADC, the INS-U provides a complete navigation solution for UAV and Helicopter applications. The unit can use time-of-flight (ToF) aiding data from a ground station for long-term GNSS-denied conditions and external position and heading to output accurate PNT information still regardless of the environment. The INS-U is a lightweight and compact solution with dimensions of 82 x 40 x 26 mm and a weight of less than 200 grams. This, along with an IP67 environmental enclosure, ensures that the INS-U can fit various applications’ environmental requirements and size and weight restrictions.

With over 20 years in the positioning and orientation sensor industry, Inertial Labs 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.
