Control of an over-actuated spacecraft using a combination of a fluid actuator and reaction wheels

Autor: Sascha Weiss, Sebastian Grau, Sascha Kapitola, Daniel Noack

Publikováno v: Acta Astronautica. 178:870-880

In 2017, Technische Universitat Berlin (TU Berlin) has launched the first space-rated fluid-dynamic actuator (FDA) on the TechnoSat mission. This type of actuator is unique with respect to its dynamic properties, as it offers a very high torque but l

Orbit deployment and drag control strategy for formation flight while minimizing collision probability and drift

Autor: Manuel A. Garcia, Sebastian Grau, Walter Frese, Yeerang Lim, Zizung Yoon

Publikováno v: CEAS Space Journal. 12:397-410

The compact form factor of nanosatellites or even smaller satellites makes them predestined for distributed systems such as formations, constellations or large swarms. However, when it comes to orbit insertion of multiple satellites, these ride share

Contraction of online response to major events.

Autor: Michael Szell, Sébastian Grauwin, Carlo Ratti

Publikováno v: PLoS ONE, Vol 9, Iss 2, p e89052 (2014)

Quantifying regularities in behavioral dynamics is of crucial interest for understanding collective social events such as panics or political revolutions. With the widespread use of digital communication media it has become possible to study massive
