Abstract
A method for detecting rotation of a carrier utilizes a device embedded in said carrier that comprises an enclosure containing a gaseous mixture of an alkali metal and a noble gas. The method includes a step of starting up (DEM-MEOP) the device during which the noble gas is polarised by utilizing metastability exchange optical pumping. The start-up step is followed by a step of acquisition (MES-SEOP) by the device of a signal representative of said rotation during which the noble gas is maintained polarised by utilizing spin exchange optical pumping. The invention extends to the device and to an inertial navigation unit integrating said device and to an inertial navigation method implementing the method for detecting rotation of the carrier.
