Robotic On-Orbit Servicing - DLR's Experience and Perspective. [PDF]
, 2006 The increasing number of launched satellites per year, calls for solutions to keep free operational space for telecommunication systems in geo-synchronized orbit, as well as to avoid the endangering of space systems in LEO (Low-Earth Orbit) and of the ...

Detection of orbital motions near the last stable circular orbit of the massive black hole SgrA* [PDF]
Astronomy & Astrophysics, 2018 We report the detection of continuous positional and polarization changes of the compact source SgrA* in high states (“flares”) of its variable near-infrared emission with the near-infrared GRAVITY-Very Large Telescope Interferometer (VLTI) beam ...

Performance Evaluation of Machine Learning Methods for Anomaly Detection in CubeSat Solar Panels
Applied Sciences, 2022 CubeSat requirements in terms of size, weight, and power restrict the possibility of having redundant systems. Consequently, telemetry data are the primary way to verify the status of the satellites in operation.

Thermal Bending of the Rotor Due to Rotor-to-Stator Rub
International Journal of Rotating Machinery, 2000 The rotor thermal bending due to the rotor-to-stator rubbing can lead to one of three types of observed rotor lateral motion: (1) spiral with increasing amplitude, (2) oscillating between rub]no-rub conditions, and (3) asymptotical approach to the rotor ...
