VN-110 Introduction

The VN-110 is a tactical-grade, high-performance Inertial Measurement Unit (IMU) and Attitude Heading Reference System (AHRS). Incorporating the latest MEMS sensor technology, the VN-110 combines 3-axis accelerometers, 3-axis gyros and 3-axis magnetometers into a compact, ruggedized, IP-68 rated aluminum anodized enclosure.

Ruggedized Packaging

The VN-110 features a precision milled, anodized aluminum enclosure designed to meet DO-160G standards. With dual I/O connectors the VN-110 offers maximum flexibility for interfacing with external GNSS receivers and IMUs. The VN-110 has an input voltage of +12 to +36 VDC power supply over a RS-422 interface.

Size: 56 x 56 x 23 mm
Power Consumption: < 2.5 watts
Weight: 160 g

Enclosed in a precision anodized aluminum enclosure, the VN-110 offers additional protection of the internal MEMs sensors and electronics. The use of precision CNC milled aluminum parts ensures that the axis alignment provided by our factory calibration process is maintained during installation in its final configuration. Interfacing with the module is made through circular push-pull 10-pin connectors.

Extended Inertial Sensor Thermal Calibration

MEMS inertial sensors are subject to several common sources of error: bias, scale factor, misalignments, temperature dependencies, and gyro g-sensitivity. To ensure the highest level of accuracy, each VN-110 sensor undergoes a rigorous calibration process to minimize these error sources. Compensation parameters calculated during these calibrations are stored on each individual sensor and digitally applied to the real-time measurements. This calibration process is performed over the full thermal operating range of the VN-110 (-40°C to +85°C).
