... In this model, the satellite is placed in the Sun-Earth Lagrangian point. The force and torque acting on the spacecraft due to drag-free control is provided by means of micro-thrusters (Gollor and Franke 2016), which are modeled as a first order system. The time constant takes into account the delays introduced by the electronic devices which driving the thrusting actuators. ...
... Electric space engines have evolved out of their shadowy existence due to the abovementioned strong points. [97][98][99][100][101] There are a large number of different types of EP systems, some still at a conceptual level, others already at a very high technological maturity level, and a few already in use in space (cf. Fig. 4). ...
... This action is provided by means of FEEP thrusters, modeled here as a first-order system with a characteristic time constant of 0.1303 s (corresponding to approximately 0.3 s rise time). The selected time constant takes into account the delays introduced by the electronic devices driving the thrusting actuators [16,17]. In this paper the FEEP thrusters are considered as a baseline actuator system because they have been identified as a key technology for future drag-free missions [17]. ...
