HGuide HG4930 IMU
The HGuide HG4930 is the highest-performing MEMS IMU for its size and cost, and is an excellent replacement for older, bulkier FOG systems. Designed to meet the requirements of UAVs, UGVs, AUVs and other robotic vehicles, its extremely low SWaP (size, weight and power) footprint allows it to be easily integrated into many different platforms and designs.
The rugged sensor solution incorporates state-of-the-art calibration and compensation, and features a proprietary internal environmental isolation system for attenuation of unwanted inputs. User-configurable options include filtering, output data rates, and communication protocols.
The HGuide HG4930 is available in three different performance grades.
