Here's what the website says:
Multiple RedundanciesBesides dual IMUs, FlightAutonomy 2.0 has more redundant modules to increase the Mavic Air’s safety level. The Vision Compass will assist the navigation system to estimate flight direction when the compass experiences interference. When only one direction of the front, bottom, or rear vision systems is functioning normally, the aircraft will still position itself successfully. There are two sets of sensor fusion algorithms based on two independent hardware platforms. When an error occurs to one set of algorithms, the aircraft will switch to the other pair seamlessly to resume normal functionality.
Wonder what are the salient differences between the "Vision Compass" and the regular old compass?
