Optomechanical Accelerometers for Geodesy [PDF]
Remote Sensing, 2022 We present a novel optomechanical inertial sensor for low-frequency applications and corresponding acceleration measurements. This sensor has a resonant frequency of 4.715 (1) Hz, a mechanical quality factor of 4.76(3) × 105, a test mass of 2.6 g, and a ...

Recent Advances in Marine Geodesy of China [PDF]
Journal of Geodesy and Geoinformation Science, 2023 The ocean accounts for approximately 71% of the total area of the Earth. Whether it is studying the shape of the Earth itself through geodesy or the future development of earth system science, strengthening the construction of ocean geodesy disciplines ...

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.

Atomic clock performance enabling geodesy below the centimetre level [PDF]
Nature, 2018 The passage of time is tracked by counting oscillations of a frequency reference, such as Earth’s revolutions or swings of a pendulum. By referencing atomic transitions, frequency (and thus time) can be measured more precisely than any other physical ...
