High-Performance Inertial Sensor for a Wide Range of Unmanned Applications
The 1750 IMU offers exceptional precision in a compact package, making it ideal for use where space is limited. By pairing the E•Core ThinFiber technology of KVH’s high-performance FOGs with solid state MEMS accelerometers, the result is an IMU that integrates easily into the most demanding applications including autonomous vehicle navigation and positioning; unmanned aerial surveillance, surveying, and mapping; humanoid robots; and oil and gas pipeline inspection equipment. Key features include:
- Drop-in replacement IMU that integrates easily into the most demanding applications
- Lower cost than systems offering comparable performance
- Low power consumption and highly adaptable
- Superior precision – bias instability ≤ 0.05°/hr, 1σ, highly accurate 6-degrees-of-freedom angular rate and acceleration data
- Compact package – 88.9 mm Dia. x 73.7 mm H (3.5” x 2.9”), <0.7 kg (<1.4 lbs.)
- Rugged design for extreme environments, with excellent shock, vibration, and thermal performance
- Industry standard Asynchronous or Synchronous RS-422 protocol
- Flexible, user-friendly programmable data output rates from 1 – 1000 Hz
- Customizable message output from both the FOGs and the integrated accelerometers
E•Core ThinFiber Technology
KVH’s proprietary polarization maintaining E•Core ThinFiber delivers outstanding precision performance in much smaller gyros and inertial systems. By minimizing the diameter of KVH’s standard E•Core fiber, the resulting ThinFiber boosts the accuracy of all KVH gyros, and allows the production of very small FOGs with very high bandwidth and very low noise.
KVH’s DSP electronics improve FOG performance in critical areas such as scale factor and bias vs. temperature, scale factor linearity, and maximum input rate. KVH’s exclusive DSP design is covered by multiple patents* and overcomes the limitations of analog signal processing, eliminating temperature-sensitive drift and rotation errors.
* This product is covered by one or more patents, including U.S. Patent #6,429,939, "DSP Signal Processing for Open Loop Fiber Optic Sensors."
