This thesis presents the development of the experimental setup allowing the measurement of two gravity gradient components, Γzz and Γzx, and the gravity acceleration. These quantities are resulted from the measuring of rubidium cold atoms acceleration, in free fall in vacuum, by atom interferometry. For gradiometry, the differential measurement is realized between two atomic clouds spatially separated. For the measurement of Γzz, the use of mobile optical lattices allows to get two atom clouds from a single atomic source. This work presents the setting up of the complete device, in particular with the built of the vacuum chamber, laser and micro-wave systems. Lasers are based on frequency-doubled telecom technology, which allows to obtain c...
