Abstract: Method and device for calibrating an antenna includes the following steps: define a number n of positions of angles for the aircraft situated in a calibration zone: measure the value of the orientation of the antenna for each position n, [#a(n), #a(n)]; define the theoretical orientation of the antenna [#a(n)*, #a(n)*] by taking account of the pitch value, of the roll value, of the yaw value (heading) for the aircraft for each position n, and of the orientation values of the satellite [#r(n), #r(n)]: [Aa(n)*, Ea(n)*]=F(H(n), P(n), R(n), ##, ##, #R, ##, Ar(n), Er(n)), where F is a chosen geometric function; define a criterion C: C=#(#a(n)?#a(n)*)2+(#a(n)?#a(n)*)2; minimize the value of the criterion C so as to determine the bias values (##, ##, #R, ##) from the values [Aa*(n), Ea*(n)] and use the said bias values to minimize the disparities between the measured angles and the theoretical angles.
