GPS-Aided Inertial Navigation System INS-U
Key Functionalities of the INS-U
4-in-1 Strapdown system integrated with:
- An Inertial Navigation System (INS) providing full output data for navigation solutions;
- Inertial Measurement Unit (IMU) yielding gyroscope/accelerometer data and gimbal stabilization;
- Air Data Computer (ADC); enhanced GPS denied navigation;
- Attitude Heading Reference System (AHRS); weapon and motion tracking system.
Design Features of the INS-U
- Gyroscope bias in-run stability (RMS Allan Variance) of 2deg/hr, 1σ
- Embedded Gyro-compensated Mini-Fluxgate magnetometers
- Total and Static Pressure Sensors for calculating Indicated Airspeed
- Small size: 82 x 40.0 x 26.0mm
- Multi-constellation U-Blox GNSS receiver (RTK-enabled)
- Newest update of on-board sensor fusion filter
INS-U
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) + Inertial Measurement Unit (IMU) + 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. 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) GNSS receiver; two barometers; miniature gyro-compensated Fluxgate magnetic 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 in both GPS-enabled and GPS-denied environments. The INS-U contains Inertial Labs new on-board sensor fusion filter, state of the art navigation, and guidance algorithms, and calibration software.
