INS-U – GPS-Aided INS with Air Data Computer
GPS-Aided Single Antenna Inertial Navigation System
The Inertial Labs GPS-Aided Inertial Navigation System (INS-U) is an IP67 rated version of the new generation, fully-integrated, combined Inertial Navigation System (INS) + Attitude & Heading Reference System (AHRS) + Air Data Computer (ADC) high-performance strapdown system, that determines position, velocity and absolute orientation (Heading, Pitch and Roll) for any device on which it is mounted.

Description
Horizontal and Vertical Position, Velocity and Orientation are determined with high accuracy for both motionless and dynamic applications.
The Inertial Labs INS-U utilizes advanced single antenna multi constellation (GPS, GLONASS, GALILEO, QZSS and BEIDOU GNSS) receiver; two Honeywell TruStability® Board Mount Pressure Sensors; a miniature gyro-compensated Fluxgate compass; 3-axes each of calibrated in full operational temperature range Advanced MEMS Accelerometers and Gyroscopes to provide accurate Position, Velocity, Heading, Pitch and Roll of the device under measure.
INS-U contains Inertial Labs new on-board sensor fusion filter, state-of-the-art navigation and guidance algorithms and calibration software.
