The HGuide HG4930 S-Class is a variant of the HG4930 MEMS IMU, specifically designed to deliver the high bandwidth and data rates required for precision stabilization of cameras, antennas and other platforms. The sensor is the highest-performing MEMS IMU for its size and cost, and is an excellent replacement for older, bulkier FOG systems. Its extremely low SWaP (size, weight and power) footprint makes it ideal for incorporation into UAVs and unmanned systems.
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 S-Class is available in three different performance grades.
