The GIESEPP (Gridded Ion Engine Standardised Electric Propulsion Platform) project will develop, build and test to TRL5 the first European Plug and Play Gridded Ion Engine System to operate ArianeGroup and QinetiQ Space Ion Engines for LEO, GEO and Space Exploration Missions.
What does Gridded Ion Engine Technologies stand for?
Gridded ion thrusters are part of the electrostatic electric propulsion thrusters. The ion thruster generate thrust in two steps. In the first step ion thrusters employ a variety of plasma generation techniques to ionize a large fraction of the propellant. In the second step the ionized fraction of the propellant is accelerated in an electrostatic field of the grid system. The ion acceleration in a grid system is the common feature of all gridded ion engines. An ion thruster consists of basically three components: the plasma generator, the accelerator grids, and the neutralizer cathode.
GIESEPP project needs and team Involvement.
The project is structured based on the following team member responsabilities:
Satellite System Requirements:
Airbus Defence and Space / Crisa
QinetiQ / ArianeGroup
Analytical Design and Test Support:
University of Southampton
The project has an overall duration of 48 months and is subdivided in 5 Phases.
Phase 1 (months 1–7)
Mission Scenarios, Platforms, Requirements and Gap Identification
Phase 2 (months 7–16)
Electric Propulsion System Definition
Phase 3 (months 16–24)
Electric Propulsion System Development and Cost Optimization
