Great technology developed by GOSY! Here is some information about their GeckoOrient I found on the company's website:
GeckoOrient automatically and intelligently merges sensor data from odometry (dead reckoning), a solid-state compass, and accelerometer-based gyroscopes (IMUs), for enhanced orientation accuracy while errand running, patrolling, or following a designated person.
Each orientation sensing system has its different strengthes and weaknesses. In the short run on uniformly smooth surfaces dead reckoning from odometry data works well. Accelerometers are also accurate in the short run and while essentially unaffected by differing surfaces, they accumulate error over a period of time. Magnetic compasses are pretty good most of the time, but can be impacted by stray magnetic fields and steel beams in a building unexpectedly. Essentially none of these sensors are sufficient when low cost is a primary design goal.

Essentially none of these sensors are sufficient when low cost is a primary design goal.
However, given GeckoSystems expertise in AI and sensor fusion, paradigms and mathematical algorithms have been developed that merge these three sometimes flawed solutions into a sensor fused result that is more accurate, repeatable, andl/or reliable than any of the three, or any two of the three. Hence GeckoSystems' mobile robot solution, GeckoOrient, is low cost and sufficient for the tasks normally expected of an indoor mobile robot.
