Unmanned vehicles are performing progressively more complex tasks-and requiring increasingly robust and accurate heading and orientation information. But existing AHRS modules leave too much room for error. They lose heading when encountering magnetic distortion; they suffer from errors when experiencing erratic motion; and often don’t provide accurate headings, even in a static environment. And at more than $2000 for a MEMS-based AHRS, it’s no wonder AHRS have only been integrated by a select few customers. So when there’s no room for error, HEC390 stays on track.
