This work focuses on the development of a cold-atom inertial sensor measuring the gravity, the vertical gravity gradient and the horizontal acceleration, by choosing technologies enabling to obtain an onboard and hybrid inertial sensor. The experimental setup generates a cold atom cloud of 87Rb, allows vertical et horizontal interferometry sequences using retroreflected contrapropagating stimulated Raman transitions, and allows a maximum free fall distance of 20 cm. The sensitivity obtained for the measurement of the gravity is 68 μGal/Hz1/2 and the optimal resolution reached 1,4 μGal after 6000 s of integration. The four-pulses interferometry sequence has been used for the measurement of the vertical gravity gradient. The sensitivity and t...
