Abstract:
1. Method of calibrating at least three gyroscopes to be calibrated in a gyroscopic system comprising at least four vibratory gyroscopes capable of changing vibration position among a plurality of vibration positions; a first measurement being provided by each of said at least three gyroscopes to be calibrated and a second measurement being provided by a combination of the respective measurements from the other gyroscopes of said system, said first and second measurements being carried out along the same measurement axis; said calibration method comprising the following steps, for each of the at least three gyroscopes to be calibrated which vibrates in one of the vibration positions: wherein the at least three gyroscopes to be calibrated are calibrated by generation of a drift model by applying step /1/ to each of the gyroscopes successively, then step /2/ to each of the gyroscopes successively, then step /3/ to each of the gyroscopes successively and finally step /4/ to each of the gyroscopes successively.
