SYSTEM AND METHOD FOR DETERMINING A VELOCITY OF A ROTORCRAFT

A rotorcraft (101) includes a flight control computer (FCC) (201), a GPS receiver (402) configured to calculate a groundspeed based on a first carrier signal, and an attitude and heading reference system (AHRS) (404) configured to determine an acceleration of the rotorcraft. The AHRS (404) is operab...

Beschreibung
Zusammenfassung:	A rotorcraft (101) includes a flight control computer (FCC) (201), a GPS receiver (402) configured to calculate a groundspeed based on a first carrier signal, and an attitude and heading reference system (AHRS) (404) configured to determine an acceleration of the rotorcraft. The AHRS (404) is operable to receive an indication of the groundspeed from the GPS receiver (402) and to calculate a velocity of the rotorcraft (101) based on the indication of the groundspeed and the acceleration. The FCC (201) is operable to receive an indication of the velocity from the AHRS (404), to generate the flight control device control signal according to the indication of velocity, and to send a flight control device control signal to one or more flight control devices.
