The Inertial Labs Single and Dual Antenna GPS-Aided Inertial Navigation System – INS is new generation of fully-integrated, combined L1 & L2 GPS, GLONASS, GALILEO and BEIDOU navigation and high-performance strapdown system, that determines position, velocity, heave and absolute orientation (Heading, Pitch and Roll) for any device on which it is mounted. Horizontal and Vertical Position, Velocity, Heave and Orientation are determined with high accuracy for both motionless and dynamic applications.

The Inertial Labs INS utilizes advanced single and dual antenna GNSS receiver, barometer, 3-axes each of calibrated in full operational temperature range precision Fluxgate magnetometers, Accelerometers and Gyroscopes to provide accurate Position, Velocity, Heading, Pitch and Roll of the device under measure. INS contains Inertial Labs new on-board sensors fusion filter, state of the art navigation and guidance algorithms and calibration software.

One of the key elements to the success of Inertial Labs INS is its use advanced single and dual antenna GNSS receiver and Inertial Labs Fluxgate Magnetometers. Inertial Labs Fluxgate Magnetometer has distinct advantages over commonly used magneto-inductive or magneto-resistive magnetometers. In operation over time and temperature fluxgate magnetometers have superior stability and repeatability. In terms of sensitivity, fluxgate magnetometers provide up to two orders of magnitude increased sensitivity. In addition to the performance advantages, unlike the chip-level magnetometer technology, fluxgate magnetometer technology has been depended on for over 70 years to provide an accurate reference to North. It remains the most reliable magnetic sensor technology for determining an object’s heading.
