Learning to become ignorant: Improving the quality of epistemic knowledge in science education

open access: yesScience Education, Volume 107, Issue 1, Page 9-27, January 2023., 2023
Abstract In considering goals for science education, it is conventional to make arguments for the utility of scientific knowledge for a variety of purposes. Less prominent are rationales based on the beauty or truth of science. In this paper, we examine how an approach to science education might be different if we shift the goals of communication to an

PPP with integer ambiguity resolution for GPS and Galileo using satellite products from different analysis centers

open access: yesGPS Solutions, 2021
Integer ambiguity resolution is the key for achieving the highest accuracy with Precise Point Positioning (PPP) and for significantly reducing the convergence time. Unfortunately, due to hardware phase biases originating from the satellites and receiver,

Assessing IGS GPS/Galileo/BDS-2/BDS-3 phase bias products with PRIDE PPP-AR

open access: yes, 2021
Ambiguity Resolution in Precise Point Positioning (PPP-AR) is important to achieving high-precision positioning in wide areas. The International GNSS (Global Navigation Satellite System) Service (IGS) and some other academic organizations have begun to ...

Analysis of the Impact of Multipath on Galileo System Measurements

open access: yesRemote Sensing, 2021
Multipath is one of the major source of errors in precise Global Navigation Satellite System positioning. With the emergence of new navigation systems, such as Galileo, upgraded signals are progressively being used and are expected to provide greater ...

New Models of Jupiter in the Context of Juno and Galileo [PDF]

open access: yesAstrophysical Journal, 2019
Observations of Jupiter’s gravity field by Juno have revealed surprisingly low values for the high-order gravitational moments, considering the abundances of heavy elements measured by Galileo 20 years ago. The derivation of recent equations of state for

Validation of the accuracy of geodetic automated measurement system based on GNSS platform for continuous monitoring of surface movements in post-mining areas

open access: yesReports on Geodesy and Geoinformatics, 2021
The problem involving the monitoring of surface ground movements in post-mining areas is particularly important during the period of mine closures. During or after flooding of a mine, mechanical properties of the rock mass may be impaired, and this may ...

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.

Preliminary study for the measurement of the Lense-Thirring effect with the Galileo satellites [PDF]

open access: yes, 2013
The precession of the orbital node of a particle orbiting a rotating mass is known as Lense-Thirring effect (LTE) and is a manifestation of the general relativistic phenomenon of dragging of inertial frames or frame-dragging.
