A simplified gravitational reference sensor for satellite geodesy [PDF]

Journal of Geodesy, 2021
A simplified gravitational reference sensor (S-GRS) is an ultra-precise inertial sensor for future Earth geodesy missions. These sensors measure or compensate for all non-gravitational accelerations of the host spacecraft to remove them in the data ...

Geodesy of irregular small bodies via neural density fields

Communications Engineer, 2022
Asteroids’ and comets’ geodesy is a challenging yet important task for planetary science and spacecraft operations, such as ESA’s Hera mission tasked to look at the aftermath of the recent NASA DART spacecraft’s impact on Dimorphos.

Application of LISA Gravitational Reference Sensor Hardware to Future Intersatellite Geodesy Missions

Remote Sensing, 2022
Like gravitational wave detection, inter-spacecraft geodesy is a measurement of gravitational tidal accelerations deforming a constellation of two or more orbiting reference test masses (TM).

A broadband VLBI system using transportable stations for geodesy and metrology: an alternative approach to the VGOS concept

Journal of Geodesy, 2021
We have developed a broadband VLBI (very long baseline interferometry) system inspired by the concept of the VLBI Global Observing System (VGOS). The new broadband VLBI system was implemented in the Kashima 34 m antenna and in two transportable stations ...
