Improving the determination of the gravity rate of change by combining superconducting with absolute gravimeter data

This paper evaluates different data-processing methods to determine the gravity rate of change, using repeated absolute gravimeter (AG) measurements and continuous monitoring by a superconducting gravimeter (SG). Based on synthetic data representative of signals observed by SGs at various station locations, we demonstrate that the addition of SG information mitigates the error in the estimation...

Superconducting gravimeter calibration by co-located gravity observations – results from GWR C025

After a 12 years’ observation in Vienna (VI), the superconducting gravimeter GWR C025 has been transferred in autumn 2007 to the new Conrad observatory (CO) 60 km SW of Vienna. It is one of few instruments which were operated at different stations. This aspect motivated a re-analysis of all calibration experiments performed so far in VI and CO, focused on the direct impact of drift effects and ...

Situation Awareness In Aviation Systems

In the aviation domain, maintaining a high level of situation awareness is one of the most critical and challenging features of an aircrew’s job. Situation awareness (SA) can be thought of as an internalized mental model of the current state of the flight environment. This integrated picture forms the central organizing feature from which all decision making and action takes place. A vast porti...
