We present and discuss a solution to the growing demand for satellite telecommunication coverage in the high-latitude geographical regions (beyond 55°N), where the signal from geostationary satellites is limited or ...
On the exploitation of differential aerodynamic lift and drag as a means to control satellite formation flight
(springer-Verlag, 2019-05-27)
Article.
Accés obert
Article.
Accés obert
For a satellite formation to maintain its intended design despite present perturbations (formation keeping), to change the formation design (reconfiguration) or to perform a rendezvous maneuver, control forces need to be ...
Development and analysis of novel mission scenarios based on Atmosphere-Breathing Electric Propulsion (ABEP)

Article.
Accés obert
Article.
Accés obert
Operating satellites in Very Low Earth Orbit (VLEO) benefit the already expanding New Space industry in applications including Earth Observation and beyond. However, long-term operations at such low altitudes require ...
Intake design for an Atmosphere-Breathing Electric Propulsion system (ABEP)

Article.
Accés obert
Article.
Accés obert
Challenging space missions include those at very low altitudes, where the atmosphere is source of aerodynamic drag on the spacecraft. To extend the lifetime of such missions, an efficient propulsion system is required. One ...
