Testing the contribution, accuracy and performance of MGEX (GNSS (GPS+GLONASS+GALILEO+BEIDOU+QZSS)) positioning in the study region

open access: yesGeodesy and Cartography, 2023
The European Commission (EC) originally proposed ideas for a European Galileo satellite navigation system in 1999. A four-phase development is planned, involving investment from both the public and commercial sectors. Galileo is intended for both public

New Interpretation of Galileo\u2019s Arthritis and Blindness [PDF]

open access: yes, 2015
Galileo Galilei (1564-1642) complained of several disorders during his life, the most important of which were chronic arthritic pains and bilateral blindness.

Test of the Gravitational Redshift with Galileo Satellites in an Eccentric Orbit. [PDF]

open access: yesPhysical Review Letters, 2018
On August 22, 2014, the satellites GSAT-0201 and GSAT-0202 of the European GNSS Galileo were unintentionally launched into eccentric orbits. Unexpectedly, this has become a fortunate scientific opportunity since the onboard hydrogen masers allow for a ...

A new Physics to support the Copernican system. Gleanings from Galileo's works [PDF]

open access: yes, 2017
Galileo's support to the Copernican theory was decisive for the revolutionary astronomical discoveries he achieved in 1610. We trace the origins of Galileo's conversion to the Copernican theory, discussing in particular the "Dialogo de Cecco di Ronchitti da Bruzene in perpuosito de La Stella Nuova".

Galileo, Ignoramus: Mathematics versus Philosophy in the Scientific Revolution [PDF]

open access: yesarXiv, 2021
I offer a revisionist interpretation of Galileo's role in the history of science. My overarching thesis is that Galileo lacked technical ability in mathematics, and that this can be seen as directly explaining numerous aspects of his life's work. I suggest that it is precisely because he was bad at mathematics that Galileo was keen on experiment and ...

Precise Orbit and Clock Products of Galileo, BDS and QZSS from MGEX Since 2018: Comparison and PPP Validation

open access: yesRemote Sensing, 2020
In recent years, the development of new constellations including Galileo, BeiDou Navigation Satellite System (BDS) and Quasi-Zenith Satellite System (QZSS) have undergone dramatic changes. Since January 2018, about 30 satellites of the new constellations

Identifying GNSS Signals Based on their Radio Frequency (RF) Features—A Dataset with GNSS Raw Signals Based on Roof Antennas and Spectracom Generator

open access: yesData, 2020
This is a data descriptor paper for a set of raw GNSS signals collected via roof antennas and Spectracom simulator for general-purpose uses. We give one example of possible data use in the context of Radio Frequency Fingerprinting (RFF) studies for ...

Galileo invariant system and the motion of relativistic d-branes [PDF]

open access: yesPhys.Rev. D59 (1999) 085007, 1998
We follow recent work and study the relativistic d-brane system in (d+1,1) dimensions and its connection with a Galileo invariant system in (d,1) dimensions. In particular, we solve d-brane systems in (2,1), (3,1) and (4,1) dimensions and show that their solutions solve the corresponding Galileo invariant systems in (1,1), (2,1), and (3,1) dimensions ...

Europa, Another Water Moon? [PDF]

open access: yes, 1999
Comparing Europa to Earth's size and oceans, this resource tells the story of the Galileo spacecraft's exploration of Europa in the late 1990's, and explains why scientists believe there may be an ocean of water underneath Europa's icy crust. Educational
