PRELIMINARY ANALYSES OF BEIDOU SIGNAL-IN-SPACE ANOMALY SINCE 2013 [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016 As BeiDou navigation system has been operational since December 2012. There is an increasing desire to use multiple constellation to improve positioning performance. The signal-in-space (SIS) anomaly caused by the ground control and the space vehicle is

Real-time precise measurements of ocean surface waves using GNSS variometric approach
International Journal of Applied Earth Observations and Geoinformation, 2022 The global navigation satellite system (GNSS) wave buoys currently in use can measure ocean surface waves but have major drawbacks regarding their real-time high-precision application due to the communication burden and high differential correction ...

Journal of Geophysical Research: Space Physics, Volume 130, Issue 8, August 2025.Abstract Multi‐spacecraft data demonstrate that intense chorus waves are excited during electron injection events that drive rapid radiation belt electron loss across a limited energy range from ∼ ${\sim} $100 to 300 keV on sub‐drift timescales through strong pitch angle diffusion.

Auroral Ionospheric Erosion at Jupiter
Journal of Geophysical Research: Space Physics, Volume 130, Issue 8, August 2025.Abstract The generation of Jupiter's main auroral oval is dominated by broadband‐energy electron beams, in contrast with the dominance of peaked electron energy spectra at Earth. Wave‐particle interactions involving Alfvén waves have been theorized to be the main mechanism driving the broadband acceleration of electrons.

Lightning Generated Whistlers: Variability of Event‐Based Wave Distributions
Journal of Geophysical Research: Space Physics, Volume 130, Issue 8, August 2025.Abstract Lightning‐generated whistlers (LGWs) are an important wave mode in the inner magnetosphere, where they play a strong role in the radiation belt slot region formation through scattering of radiation belt electrons into the loss cone. Recent LGW studies have calculated time‐averaged wave parameters which are then used to calculate quasi‐linear ...

PERIOD CHANGE IN THE CONTACT SYSTEM AW UMA
Odessa Astronomical Publications, 2017 Nine new minima were determined from the UBV photoelectric observations obtained in 1992 and 1995-6. They were used to derive the new ephemerides of AW UMa. The mid-eclipse brightening best visible in U colour was detected.

The Benefit of Space Clocks for the Deep Space Network
Radio Science, Volume 60, Issue 8, August 2025.Abstract Ground‐based atomic clocks have been the foundation of the Deep Space Network's (DSN's) ability to provide high‐precision tracking to deep space users for navigation and radio science since its inception in the mid‐1960s. This paper describes the development of space clocks that could aid the DSN and the solar system exploration enterprise ...

Revue LISA, 2008 Controversy was raging in England in the late 1570s and early 1580s as Puritans attacked the evils of the age and above all the stage. Stephen Gosson is well-known for having joined the anti-theatrical polemics in his Schoole of Abuse.
