On orbit performance of the GRACE Follow-On Laser Ranging Interferometer
Klaus Abich, Claus Braxmaier, Martin Gohlke +80
The Laser Ranging Interferometer (LRI) instrument on the Gravity Recovery and Climate Experiment (GRACE) Follow-On mission has provided the first laser interferometric range measur…
Design of Dedicated Tilt-to-Length Calibration Maneuvers for LISA
Henry Wegener, Sarah Paczkowski, Marie-Sophie Hartig +3
Tilts of certain elements within a laser interferometer can undesirably couple into measurements as a form of noise, known as tilt-to-length (TTL) coupling. This TTL coupling is an…
Comparing GRACE-FO KBR and LRI ranging data with focus on carrier frequency variations
Vitali Müller, Markus Hauk, Malte Misfeldt +4
The GRACE Follow-On satellite mission measures distance variations between the two satellites in order to derive monthly gravity field maps, indicating mass variability on Earth on…
Scale Factor Determination for the GRACE-Follow On Laser Ranging Interferometer including Thermal Coupling
Malte Misfeldt, Vitali Müller, Laura Müller +2
The GRACE Follow-On satellites carry the very first inter-spacecraft Laser Ranging Interferometer (LRI). After more than four years in orbit, the LRI outperforms the sensitivity of…
In-Depth Modeling of Tilt-To-Length Coupling in LISA's Interferometers and TDI Michelson Observables
Gudrun Wanner, Sweta Shah, Martin Staab +2
We present first-order models for tilt-to-length (TTL) coupling in LISA, both for the individual interferometers as well as in the time-delay interferometry (TDI) Michelson observa…
