VectorNav INS and KVH IMU

VectorNav Technologies and KVH Industries have announced that KVH’s fiber optic gyro (FOG)-based 1750 IMU and 1775 IMU will now be offered to enhance the operation of VectorNav’s VN-210 and VN-310 Tactical Series GNSS-aided inertial navigation systems.

The VectorNav Tactical Series products with KVH’s FOG-based inertial measurement units (IMUs) combine the precision and reliability of KVH’s FOG technology with the robust filters and high-performance navigation algorithms of VectorNav’s inertial navigation systems. The combined capabilities represent an effective alternative to larger inertial navigation systems and provide improved accuracy in challenging environments such as unmanned aerial vehicles (UAVs) and other unmanned platforms.

“We are pleased to feature KVH technology in our Tactical Series and give our customers the option of utilizing a FOG-based IMU for higher precision performance to support a wide range of demanding applications,” says Jakub Maslikowski, director of sales and marketing for VectorNav.

VectorNav’s Tactical Series includes an onboard microelectromechanical systems (MEMS)-based IMU, which provides some advantages for customers who have constraints in terms of size and weight in their navigation and stabilization applications. However, in terms of inertial accuracy, the most demanding applications require performance that can only be delivered by FOG-based IMUs.

The VectorNav Tactical Series products with KVH FOG-based IMUs are designed for such applications as: SATCOM-on-the-Move; gimbal and camera pointing and stabilization; weapons systems targeting and stabilization; autonomous vehicle navigation; LiDAR mapping; georeferencing; or any application where MEMS-based solutions are unable to deliver sufficient accuracy and precision.

“The combination of VectorNav’s Tactical Series products with our FOG-based IMUs provides a great solution for applications that require advanced inertial navigation capability and FOG-level IMU performance,” says Jay Napoli, vice president of FOG/OEM sales for KVH.

A single cable connects the two systems, running from KVH’s 1750 IMU or 1775 IMU directly to the auxiliary port on the VN-210 or VN-310. This pairing creates a fully integrated FOG-based inertial navigation system designed to provide a high-accuracy, continuous positioning, velocity, and attitude solution.
