Abstract
The invention relates to an interferometric gyroscope-type ultracold atom inertial sensor (10) comprising: an atomic chip (ACh) including at least one set of a first and a second sensor element (SENA, SENB), a power supply device (PSD), the magnetic field generator and the power supply device being configured to apply the magnetic field, direct currents, and microwave signals according to a predetermined sequence, the arrangement of said group of one or more conducting elements of each sensor and said sequence being further configured such that the trajectory (TR1) associated with the first sensor element and the trajectory (TR2) associated with the second sensor element are identical and traversed simultaneously and in opposite directions by the clouds of ultracold atoms associated with the same internal state, the sensor further comprising a detection system (SDET).
