Satellite geodesy: Methods [PDF]

open access: yesEos, Transactions American Geophysical Union, 1971
General Theory. Analytic solutions for the motion of a near‐earth satellite are of practical importance for orbit prediction and establishment of reference orbits I (intermediaries) for minimizing perturbations from which the geodetic information is extracted.

A new laser-ranged satellite for General Relativity and space geodesy: IV. Thermal drag and the LARES 2 space experiment [PDF]

open access: yesThe European Physical Journal Plus, 2018
.In three previous papers we presented the LARES 2 space experiment aimed at a very accurate test of frame-dragging and at other tests of fundamental physics and measurements of space geodesy and geodynamics. We presented the error sources in the LARES 2

Rapid shallow megathrust afterslip from the 2021 M8.2 Chignik, Alaska earthquake revealed by seafloor geodesy

open access: yesScience Advances, 2023
The shallower portions of subduction zone megathrust faults host Earth’s most hazardous tsunamigenic earthquakes, yet understanding how and when they slip remains elusive because of challenges making seafloor observations.
