    dct:description """
              In the first part of this work causes of gravity anomalies are studied, along with causes of noise. The feasibilities of a few industrial applications involving mobile gravity or gravity gradient meters were hence evaluated. These applications include in particular the realization of a collision avoidance device for underwater navigation, detection of underground void spaces and tsunami wave detection. Classical noises encountered in on-board gravity measurements are studied, as well as the less conventional gravity noise caused by ocean waves. The second part of the work is devoted to the implementation of a matter waves interferometry gravimeter. The particularity of the device is to use atoms trapped in the vicinity of a silicon carbide atom chip. The goal of the project is to reach for the measurement accuracies of current matter waves gravimeters with free falling atoms, with a principle that does not imply a proportionality between the size of the device and its sensitivity limit. We hope to demonstrate a proof of concept that may lead to a new generation of atomic gravimeters that are compact and therefore better suited for mobile uses. Coherent splitting of a non-condensed atom cloud for metrology purposes is probably the main challenge of the project
