Gill Static Pressure Port for Multi-rotor MAVs

Micro aerial vehicles that use a barometric altimeter are often subject to altitude errors due to aerodynamic effects around the airframe. This is most common in rapid horizontal flight. Conventional aircraft avoid this problem with the use of a pitot tube static pressure port. However, multirotors that can move in any of 4 axes need a solution that works in any direction. A disk-shaped static pressure port can accomplish this.

The Gill static pressure port is a type of barometer port that is
