(International Astronautical Federation, 2022)
Conference report
Restricted access - publisher's policyThe DISCOVERER project commenced in 2017 with the aim to advance the development of key technologies to enable the commercially viable, sustained operation of satellites in very low Earth orbits (VLEO). Funded by the ... -
Platform and system design study of a VLEO satellite platform using the IRS RF Helicon-based Plasma Thruster
(International Astronautical Federation, 2022)
Conference report
Restricted access - publisher's policyTo achieve a feasible lifetime of several years, most satellites are deployed in orbits higher than 400 km. Drag of residual atmosphere causes a slow orbit decay, resulting in the deorbit of the spacecraft. However, e.g. ... -
Very low Earth orbit constellations for Earth observation
(International Astronautical Federation, 2022)
Conference report
Restricted access - publisher's policyVery Low Earth Orbits (VLEOs), those below 450 km, present a number of benefits and challenges for the development and operation of Earth observation spacecraft at both the system and mission level. This paper examines the ... -

Conference lecture
Restricted access - publisher's policyA hyper-thermal orbital aerodynamics test facility is described. The Rarefied Orbital Aerodynamics Research facility(ROAR)is a dedicated apparatus designedto simulate the atmospheric flow in very low Earth orbits(VLEO) to ... -
Inductive Plasma Thruster (IPT) for an Atmosphere-Breathing Electric Propulsion System: design and set in operation
(2019)
Conference report
Open AccessChallenging space missions include those at very low orbits, where the atmosphere is source of significant drag on a satellite. Therefore, an efficient dragcompensation propulsion system is required to extend the mission ... -
RF Helicon-based Plasma Thruster (IPT): Design, Set-up, and First Ignition
(International Astronautical Federation, 2019)
Conference report
Restricted access - publisher's policyTo extend missions lifetime at very low altitudes, an efficient propulsion system is requiredto compensate for aerodynamic drag. One solution is Atmosphere-Breathing Electric Propulsion (ABEP). It collects atmospheric ... -
