Beginnings of Satellite Navigation

Kartografija i Geoinformacije, 2008
The first satellite navigation system called the Navy Navigation Satellite System (NNSS) or TRANSIT was planned in the USA in 1958. It consisted of 5-6 artificial Earth satellites, was set in motion for the USA military in 1964, and in 1967 for civilian ...

Satellite Data Applications for Sustainable Energy Transitions

Frontiers in Sustainability, 2022
Transitioning to a sustainable energy system poses a massive challenge to communities, nations, and the global economy in the next decade and beyond. A growing portfolio of satellite data products is available to support this transition. Satellite data complement other information sources to provide a more complete picture of the global energy system ...

Accurate and Efficient Photoeccentric Transit Modeling

The Astronomical Journal, 2023
A planet’s orbital eccentricity is fundamental to understanding the present dynamical state of a system and is a relic of its formation history. There is high scientific value in measuring the eccentricities of Kepler and Transiting Exoplanet Survey ...

Prognostic Factors of Melanoma Patients with Satellite or In-Transit Metastasis at the Time of Stage III Diagnosis

PLoS ONE, 2013
Background Prognosis of patients with loco-regional skin metastases has not been analyzed in detail and the presence or absence of concurrent lymph node metastasis represents the only established prognostic factor thus far.

Structural Transitions of Satellite Tobacco Mosaic Virus Particles

Virology, 2001
Satellite tobacco mosaic virus (STMV) can undergo at least two physical transitions that significantly alter its mechanical and structural characteristics. At high pH the 17-nm STMV particles expand radially by about 5 A to yield particles having diameters of about 18 nm.

Estimates of African Dust Deposition Along the Trans‐Atlantic Transit Using the Decadelong Record of Aerosol Measurements from CALIOP, MODIS, MISR, and IASI

Journal of Geophysical Research - Atmospheres, 2019
Deposition of mineral dust into ocean fertilizes ecosystems and influences biogeochemical cycles and climate. In situ observations of dust deposition are scarce, and model simulations depend on the highly parameterized representations of dust processes ...

Investigating Transit Timing Variations in the Ultrashort Period Exoplanet WASP-19b

The Astronomical Journal
In this study, we present a comprehensive analysis of transit timing variations (TTVs) in the ultrashort-period gas giant WASP-19b, which orbits a G-type main-sequence star.
