Development of a Compact Electronic System for the Absolute Aero Quanten-Gravimetry (AeroQGrav) Project — •Patrick Rößler, Knut Stolzenberg, Ernst Rasel, and Dennis Schlippert — Leibniz Universität Hannover - Institut für Quantenoptik
To map the Earth’s gravitational field within a restricted area we utilize an airplane as a platform for combining inertial and positional sensors at lower altitudes. Within a measuring duration of 5 s we are aiming for a spatial resolution of 0.3 to 0.5 km, by the implementation of a cold atom quantum gravimeter with the sensitivity of 1 µm/s2 and combine it with the data stream of the GNSS position system, a terrestrial laser scanner and a laser velocity meter. The presented work shows the requirements to build a robust, fast and precise electronic system to operate the quantum gravimeter and merge the aforementioned sensors data streams using sensor fusion in the noisy environment of an airplane.
