High heading precision is crucial for a safe Mixed Reality overlay provided by Aero Glass.

The video below shows a flight with 0.1° heading precision and another with a 1.3° precision, with the latter exhibiting a 110ft (33m) overlay offset from a distance of 0.86nm (1.6km). This is misleading the pilot and can be potentially dangerous.

This is why Aero Glass is committed to provide a highly precise Mixed Reality overlay using very precise GNSS-INS systems.
