VN-110
Tactical-grade MEMS IMU/AHRS with 0.6°/hr typical gyro bias, offered in an IP-68 MIL-STD rugged enclosure or as the VN-110E embedded module.
Description
The VN-110 is a tactical-grade IMU/AHRS combining 3-axis accelerometers, gyroscopes and magnetometers to compute a real-time 3D orientation solution over the full 360° of motion. It uses VectorNav's proprietary filtering and VPE 2.0 for disturbance rejection.
Key features
- Precision-milled aluminum unit, IP-68 rated, designed to DO-160G, MIL-STD-1275E, MIL-STD-461G and MIL-STD-810G
- Dual I/O connectors for external GNSS receivers and IMUs
- VN-110E miniature board-mount module, 31 x 31 x 12 mm and 12 g
- Gyro in-run bias stability < 1°/hr (0.6°/hr typical); 0.05° RMS static pitch/roll
- 1 kHz IMU data and 400 Hz attitude data
- Made in the USA, ITAR-free
Applications
Listed in VectorNav's bathymetric survey application note; suited to marine platforms that need precise heading, roll and pitch in a rugged package.
