Asteroid masses obtained with INPOP planetary ephemerides

open access: yesMonthly notices of the Royal Astronomical Society, 2019
We present here masses of 103 asteroids deduced from their perturbations on theorbits of the inner planets, in particular Mars and the Earth. These determinations and theINPOP19a planetary ephemerides are improved by the recent Mars orbiter navigation ...

The Deformation Response of Hydrological Loading Due To Water Level Changes in Qinghai Lake

open access: yesWater Resources Research, Volume 61, Issue 5, May 2025.
Abstract Over the past 18 years, the water level of Qinghai Lake has risen by more than 4 m, resulting in a total mass increase of approximately 22 Gt. This increase may have impacted the surface deformation and fault activity within a 100 km radius of the lake.

New Models of Jupiter's Magnetopause and Bow Shock Through the Juno Prime Mission: Probabilistic Location, Shape, and Internally‐Driven Variation

open access: yesJournal of Geophysical Research: Space Physics, Volume 130, Issue 5, May 2025.
Abstract The interaction between Jupiter's magnetosphere and the solar wind is not well‐constrained: while internal energetic plasma processes are thought to dominate plasma circulation, the solar wind nonetheless exerts significant control over the shape and scale of the whole structure.

A 16-parameter GEO Broadcast Ephemeris [PDF]

open access: yesJournal of Geodesy and Geoinformation Science, 2018
Currently, the broadcast ephemerides used in GEOs are same as those of the MEOs and IGSOs in the BeiDou navigation constellation. However, a trade-off strategy, i.e.

The Solar Lense-Thirring effect: perspectives for a future measurement

open access: yes, 2016
The predicted Lense-Thirring perihelion precession of Mercury induced by the Sun's angular momentum through its general relativistic gravitomagnetic field amounts to 2 milliarcseconds per century.

Detection of Landslide‐Generated Tsunami by Shipborne GNSS Precise Point Positioning

open access: yesGeophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract Precise point positioning (PPP) of ships using Global Navigation Satellite System (GNSS) data reveals the precise movements of marine vessels. This method may quantify anomalies in sea surface height with implications for oceanographic monitoring, exploration, and tsunami warning. The GNSS PPP data from the R/V Sikuliaq, a research ship of the

Galileo Single Point Positioning Assessment Including FOC Satellites in Eccentric Orbits

open access: yesRemote Sensing, 2019
On August 2016, the Milena (E14) and Doresa (E18) satellites started to broadcast ephemeris in navigation message for testing purposes. As the Galileo constellation is not yet complete. It is very important to have two more satellites available since the

Ephemerides and Celestial Mechanics [PDF]

open access: yesHighlights of Astronomy, 1986
When solving some abstract problems in mechanics related to the dynamics of bodies and systems, the notion of an inertial frame of reference is introduced in an apparently clear and natural way by simply drawing its coordinate axes and then paying no further attention to the system of reference which is then taken for granted.
