It is challenging or infeasible to precisely measure the mass of small asteroids using state-of-the-art without a dedicated spacecraft rendezvous mission, which are typically limited one few asteroid targets. Alternatively, flyby missions offer possibility visiting multiple but lack sensitivity for all largest asteroids. In these encounters, Earth-based two-way Doppler used change in spacecraft...

A Bose-Einstein condensate (BEC) is frequently described as the matter-wave analog of an optical laser – the preferred source for optical interferometry. In this project, we have demonstrated an atom interferometer-based gravimeter using a Rb Bose-condensed source [1]. Our data represent the highest fringe visibility yet achieved in such a device (Fig. 1), for both standard, and large-momentum-...

The precise calibration of relative gravity meters is essential for the accuracy of gravimetric surveys. We show that in the new Zugspitze calibration system established in 2004 – 2005 excellent accuracies of the linear calibration factor of relative gravity meters in the range of 1–2 * 10 can be obtained. The calibration system is particularly useful for the precise calibration of Scintrex lin...

We present a semi-automated procedure for detection and removal of residual erratic observations from a gravimetry database. The procedure is based on geographic information system (GIS) technology, provided by the Busstop system, a spatio-temporal information system prototype. The procedure is described through the presentation of a case study showing its use (and usefulness) in a limited area...
