Processing 20 years of SLR observations to GNSS satellites [PDF]
, 2014 We process 20 years of SLR observations to GPS and GLONASS satellites using the reprocessed 3-day and 1-day microwave orbits provided by the Center for Orbit Determination in Europe (CODE) for the period 1994-2013.

Mapping Global GNSS Vertical Velocities to Solid Earth Figure Change
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.Abstract The Earth's figure evolves in response to glacial isostatic adjustment (GIA), surface‐mass redistribution, and rotational and mantle‐driven processes. While temporal changes in the geoid's flattening are monitored through low‐degree gravity field harmonics, the geometric response of the solid Earth can be assessed independently from GNSS ...

Ground-based optical position measurements of space debris in low earth orbits [PDF]
, 2013 The increasing amount of space debris requires the satellite operators to handle a growing number of collision risk assessments in order to eventually perform collision avoidance manoeuvrers.

Advanced Optical Materials, Volume 14, Issue 31, August 21, 2026.Metasurface shows selective solar–thermal energy conversion with high‐activity solar/laser‐driven chemistry. The breakthrough is co‐designing broadband FP‐cavity + plasmonic LSPR/SLR resonances in an ultra‐thin metamaterial so that it not only harvests the most efficient proportion of solar radiation but also suppresses mid and IR emissivity. Moreover,

Empirical Assessment of Storm‐Time Thermospheric Density Inversion Methods From LEO POD Data
Earth and Space Science, Volume 13, Issue 8, August 2026.Abstract Thermospheric mass density is one of the largest sources of operational uncertainty for spacecraft in low Earth orbit, particularly during geomagnetic storms. The growing population of Global Navigation Satellite System‐equipped satellites presents a data set of opportunity: precise orbit determination (POD) data streams can be used to ...
