Abstract It is difficult to recover drones for small ships (such as destroyers). Therefore, it necessary design a new carrier-borne UAV recovery platform, achieving the purpose of rapid offshore UAV. This paper presents fast unfolding and folding inflatable structure ship recovery. analyze some static response platform. Firstly, parking positions on runway surface factor. Secondly, materials al...

Marine gravimetry provides high-quality gravity measurements, particularly in coastal areas. After the update of new sensors GFZ’s air-marine gravimeter Chekan-AM, measurements showed a significant improvement from first campaign DENEB2017 with an accuracy 0.3/2=0.21 mGal @ 1 km along tracks, which is at highest level marine gravimetry. Then, these were used to assess data derived satellite alt...

[1] The Gravity Recovery and Climate Experiment (GRACE) provides quantitative measures of terrestrial water storage (TWS) change. GRACE data show a significant decrease in TWS in the lower (southern) La Plata river basin of South America over the period 2002–2009, consistent with recognized drought conditions in the region. GRACE data reveal a detailed picture of temporal and spatial evolution ...

Global assessment of the spatiotemporal variability in terrestrial total water storage anomalies (TWSA) in response to hydrologic extremes is critical for water resources management. Using TWSA derived from the gravity recovery and climate experiment (GRACE) satellites, this study systematically assessed the skill of the TWSA-climatology (TC) approach and breakpoint (BP) detection method for id...

We present an approach to calculate scalar and tensor gravity utilizing the massively parallel architecture of consumer graphics cards. Our parametrization is based on rectilinear blocks with constant density within each blocks. This type of parametrization is well suited for inversion of gravity data or joint inversion with other datasets, but requires the calculation of a large number of mode...

The formation control of a long-distance, drag-free, low-thrust, low-Earth orbit satellite is outlined, in view of future Earth-gravity monitoring missions employing long baseline interferometry (> 10 km) and lasting at least six years. To this purpose, a formation consisting of two drag-free satellites, orbiting at a fixed distance in a sun-synchronous orbit, has been proposed as a baseline. F...
