TheEuropean Space Agency’s (ESA) CELESTE programme aims to define and evaluate a
new generation of satellite navigation systems based on low Earth orbit (LEO)
constellations, complementing the current GNSS systems in medium Earth orbit
(MEO). This programme addresses challenges relating to technology, system
architecture, interoperability and the provision of high-precision, resilient
and low-latency navigation services. The next phase of the programme is CELESTE
In-Orbit Preparation (IOP), a large-scale project covering the end-to-end
system and integrating multiple sub-programmes. The Systems Engineer role aims
to take on technical responsibility for the CELESTE IOP programme, or one of
its sub-programmes, leading the definition of the architecture, requirements
management and technical consistency of the system.
