Cosmic Ray Anisotropy Generated by the June 22nd 2015 Interplanetary Events
Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.Abstract On 22 June 2015, the near Earth interplanetary space was perturbed by a series of high‐speed streamers and interplanetary coronal mass ejections associated with an active region and two low‐latitude coronal holes. The interaction of these disturbances gave rise to the complex solar wind structure observed at 1 au.

Izračun položaja GPS-satelita iz podatkov preciznih efimerid : GPS-orbit computation from precise ephemeris data [PDF]
Geodetski Vestnik, 2005 The article describes the theoretical point of view of the GPS precise ephemerides application that should be used in most precise GPS processing. Regarding broadcast, precise ephemerides allow us to achieve a much better accuracy of the final GPS ...

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 9, September 2026.Abstract Global Navigation Satellite System (GNSS) airborne radio occultation (ARO) observations, collected during Atmospheric River Reconnaissance (AR Recon) campaigns, enhance AR sampling beyond traditional dropsondes. Assimilating ARO bending angles requires a forward operator accounting for ARO geometry and proper integration in a data assimilation

Consistent tidal and rotational models for satellites in synchronous rotation
Astronomy & AstrophysicsTidal dissipation in natural satellites plays a crucial role in shaping their thermal state, internal structure, and evolution; for example, sustaining subsurface oceans in Europa and Enceladus and driving Io’s volcanic activity.

Subtabulated Lunar and Planetary Ephemerides [PDF]
, 1960 In a joint JPL-STL effort the planetary ephemerides have been collected on IBM 704-709 magnetic tape, and a series of routines have been written to utilize these tapes.

Galilean satellite ephemerides E5
, 1998 New ephemerides of Jupiter's Galilean satellites are produced from an analysis of CCD astrometric data, Voyager-mission optical navigation images, mutual event observations, photographic plates, and eclipse timing observations. The resulting parameters,
