Extracting ocean‐generated tidal magnetic signals from Swarm data through satellite gradiometry

open access: yes, 2016
Ocean‐generated magnetic field models of the Principal Lunar, M2, and the Larger Lunar elliptic, N2, semidiurnal tidal constituents were estimated through a “Comprehensive Inversion” of the first 20.5 months of magnetic measurements from European Space ...

On the interpretation of satellite-derived gravity and magnetic data for studies of crustal geology and metallogenesis [PDF]

open access: yes
Satellite-derived global gravity and magnetic maps have been shown to be useful in large-scale studies of the Earth's crust, despite the relative infancy of such studies.

Utility of Slepian basis functions for modeling near-surface and satellite magnetic anomalies of the Australian lithosphere

open access: yesEarth, Planets and Space, 2017
The utility of frequency- and space-limited spherical harmonic Slepian basis functions for magnetic anomaly modeling over restricted spherical patches of the Earth was investigated using combined near-surface scalar and CHAMP satellite vector ...

Automated Global Feature Analyzer - A Driver for Tier-Scalable Reconnaissance [PDF]

open access: yes, 2008
For the purposes of space flight, reconnaissance field geologists have trained to become astronauts. However, the initial forays to Mars and other planetary bodies have been done by purely robotic craft.

Effect of proton irradiation on the normal state low-energy excitations of Ba(Fe$_{1-x}$Rh$_x$)$_2$As$_2$ superconductors [PDF]

open access: yes, 2017
We present a \asnmr Nuclear Magnetic Resonance (NMR) and resistivity study of the effect of 5.5 MeV proton irradiation on the optimal electron doped ($x=$ 0.068) and overdoped ($x=$ 0.107) Ba(Fe$_{1-x}$Rh$_x$)$_2$As$_2$ iron based superconductors.

Performance interface document for the S-band diplexer for space users of NASA networks [PDF]

open access: yes
This report discusses the test results and interfacing information of the S-band diplexer development program supported by RTOP 310 funding. The program was implemented to reduce the S-band transponder noise figure by minimizing the receive channel ...
