Inertial Solutions in Autonomous Ground Reference Systems

Breakthrough Performance in a Small Inertial System
The 1750 IMU is an ultra-compact, extremely precise inertial sensor system ideal for autonomous applications where size, weight, and power consumption must be minimized. Leveraging patented KVH technology, the 1750 IMU incorporates the world’s smallest precision fiber optic gyro – KVH’s remarkable DSP-1750 – with very low noise MEMS accelerometers. Result: a high-performance commercial-off-the-shelf (COTS) system with excellent bias stability and repeatability.

Rugged, Innovative Design
Contained in one ultra-compact package, the 1750 IMU measures 88.9 mm Dia. x 73.7 mm h (3.5" x 2.9"), weighs less than .7 kg (1.45 lbs.), and has a power consumption of 5 watts (typical). It features excellent shock, vibration, and thermal functionality, and is designed for accurate performance in extreme environments and mission-critical applications including weapon platforms, radar stabilization, and remote weapons.

Maximum Flexibility 
The 1750 IMU offers ease of use and high adaptability, featuring industry standard RS-422 protocol, with user programmable data output rates from 1 to 1000 Hz. Its potential applications include a vast range of navigation and guidance systems, optical equipment, and precision pointing. The 1750 IMU is equally well suited for new or drop-in replacement designs.

1750 IMU: How to Choose the Right Fiber Optic Gyro



Meeting of the Minds 2014: Flyover Mapping & Modeling

The Carnegie Mellon team is participating in the Google Lunar XPRIZE, constructing a system to capture high resolution images for use in mapping of the moon’s surface. Multiple sensors are being employed by the team, the 1750 IMU is crucial to providing precise relative motion of the platform, enabling extremely accurate modelling of the ground below.



Featured Options

  • User has opportunity to create the desired message output from both the fiber optic gyros and integrated accelerometers of the Series 1750 IMU.
  • Package dimensions and mounting features enable easy drop-in replacement.
  • FOG/IMU Developer’s Kit with easy-to-use software accelerates your IMU and FOG integration, development, and interface efforts. Learn more.


Exclusive Technology

  • E•Core ThinFiber
    KVH’s proprietary polarization maintaining E•Core ThinFiber delivers outstanding precision performance in much smaller size gyros, such as the DSP-1750. By reducing the overall diameter of KVH’s standard E•Core fiber, the resulting E•Core ThinFiber dramatically increases the accuracy of our standard size gyros, and produces small FOGs that deliver extremely high bandwidth and low noise.
  • DSP Technology
    KVH’s Digital Signal Processing (DSP) electronics improve fiber optic gyro performance in such critical areas as scale factor and bias versus temperature, scale factor linearity, turn-on to turn-on repeatability, and maximum input rate. The innovative DSP design is covered by multiple patents and overcomes the limitations of analog signal processing, virtually eliminating temperature-sensitive drift and rotation errors.
