Precise orbit determination and point positioning using GPS, Glonass, Galileo and BeiDou

open access: yesJournal of Geodetic Science, 2014
State of the art Precise Point Positioning (PPP) is currently based on dual-frequency processing of GPS and Glonass navigation systems. The International GNSS Service (IGS) is routinely providing the most accurate orbit and clock products for these ...

The impact of physicochemical features of carbon electrodes on the capacitive performance of supercapacitors: a machine learning approach

open access: yesScientific Reports, 2023
Hybrid electric vehicles and portable electronic systems use supercapacitors for energy storage owing to their fast charging/discharging rates, long life cycle, and low maintenance.

Evalution of the Accuracy and Performance of Multi-GNSS (MGEX) Positioning for Long Baselines by Using Different Software [PDF]

open access: yesJournal of Geodesy and Geoinformation Science, 2023
The Global Positioning System (GPS) is a GNSS constellation, but GNSS is not always GPS. GPS is one of the GNSS constellations used around the world. The GNSS constellations include GPS (US), QZSS (Japan), Beidou/BDS (China), Galileo (EU), and GLONASS ...

Robust Spin Splitting and Fermiology in the Layered Altermagnet CoNb4${\rm CoNb}_4$Se8${\rm Se}_8$

open access: yesAdvanced Materials, EarlyView.
The emergence of an altermagnetic phase is demonstrated in the cobalt‐intercalated superconducting 2H‐NbSe2 polymorph. A combined theoretical and experimental approach directly probes the magnetism, the altermagnetic lifting of Kramers degeneracy, and the electronic phase space, establishing CoNb4Se8 as the first g‐wave altermagnetic layered material ...

Galileo vs Aristotle on Free Falling Bodies [PDF]

open access: yes, 2004
This essay attempts to demonstrate that it is doubtful if Galileo's famous thought experiment concerning falling bodies in his 'Dialogues Concerning Two New Sciences' (Galileo 1954: 61-64) actually does succeed in proving that Aristotle was wrong in ...

Understanding mathematical abstraction in the formularization of Galileo's law

open access: yesІсторія науки і техніки, 2022
Galileo's revolution in science introduced an analytical method to science that typifies the overall modern thinking of extracting, abstracting, and grasping only critical aspects of the target phenomena and focusing on “how”, which is a quantitative ...
