Determination of crustal motions using satellite laser ranging [PDF]

open access: yes
Satellite laser ranging has matured over the last decade into one of the essential space geodesy techniques. It has demonstrated centimeter site positioning and millimeter per year velocity determinations in a frame tied dynamically to the mass center of

Impact of SLR long-term mean range biases on SLRF2020-based orbits of altimetry satellites

open access: yesEarth, Planets and Space
In 2022 and 2023, the new (2020) realizations of the International Terrestrial Reference System (ITRS), namely ITRF2020, JTRF2020, and DTRF2020, were published.

Proposal for an Optical Test of the Einstein Equivalence Principle

open access: yes, 2019
The Einstein Equivalence Principle (EEP) underpins all metric theories of gravity. Its key element is the local position invariance of non-gravitational experiments, which entails the gravitational red-shift.

Geophysical interpretation of satellite laser ranging measurements of crustal movement in California [PDF]

open access: yes
As determined by satellite laser ranging the rate of contraction of a 900 kilometer baseline between sites located near Quincy in northern California and San Diego in southern California is about 61 to 65 mm/yr with a formal uncertainty of about 10 mm/yr.

Combination of GNSS and SLR observations using satellite co-locations [PDF]

open access: yes, 2018
Satellite Laser Ranging (SLR) observations to Global Navigation Satellite System (GNSS) satellites may be used for several purposes. On one hand, the range measurement may be used as an independent validation for satellite orbits derived solely from GNSS

Comparison of Site Velocities Derived from Collocated GPS, VLBI and SLR Techniques at The Hartebeesthoek Radio Astronomy Observatory (Comparison of Site Velocities)

open access: yesJournal of Geodetic Science, 2014
Space geodetic techniques provide highly accurate methods for estimating bedrock stability at subcentimetre level. We utilize data derived from Satellite Laser Ranging (SLR), Very Long Baseline Interferometry (VLBI) and Global Positioning Systems (GPS ...

18.6-yr tidal variations in J2 observed from 48-yr satellite laser ranging (SLR)

open access: yesGeophysical Journal International
SUMMARY Analysis of the 48-yr of satellite laser ranging data of multiple satellites shows that long-term variations in the Earth's dynamical oblateness represented by the second-degree zonal harmonic J2 is best characterized by the superposition of a quadratic trend, 10.5- and 18.6-yr variations.
