Application Gallery

Pipeline inspection gauges used for cleaning and inspecting the pipelines rely on KVH precision IMUs to provide inertial navigation without GNSS input.
Drilling operations require rugged, high-performance KVH FOGs to provide accurate orientation information.
Ultra-high definition cameras utilize KVH high accuracy IMUs and FOGs to help their stabilization systems to produce rock steady images.
Precision inertial navigation data from KVH IMUs is required to guide pipeline inspection gauges used for cleaning and inspecting underground gas and oil pipelines. 
Compact highly accurate FOGs and IMUs from KVH are integrated into the navigation systems of UAVs; these sensors are also used to stabilize UAV payloads.
