The ESEO Program
• The ESEO Program is financed and
technically supported by the ESA
Education and Knowledge
Management Office reporting to the
Cabinet of the ESA Director General
(DGC-DE)
• The satellite is mainly developed by
students preparing their Master or
PhD thesis supported by ESA experts
• ECSS standards are considered as
reference documentation

• SITAEL S.p.A. belongs to the holding Angelo
Investments, a worldwide leading Transportation
and Aerospace Group composed by synergic
high-tech companies with more than 1000 highly
skilled employees.
• SITAEL, ALTA and ALMASpace, the three space
companies of Angelo Investments Group,
completed the process of merging into a single
company on December 31st, 2014.
• In the context of the ESEO Program,
ALMASpace is the prime contractor and
responsible for the mission implementation.
ESEO in brief - 1
• ESEO is the third mission managed by
the ESA’s Education and Knowledge
Management Office and builds upon
the experience gained with SSETI
Express (launched in 2005) and the
YES2 tether and re-entry capsule
experiment (launched in 2007);
• The project is currently at the end of
Phase C, the detailed design stage,
with students actively involved from
eight universities across all Europe;
• The ESEO spacecraft is to be launched
into Low Earth Orbit in 2016.

• ESEO University Network:
Launcher and Orbit - 1
• Launcher: VEGA is considered the baseline but
additional launchers are possible alternative candidates.
ESA is in the process to select a suitable launch vehicle.
• Orbit: The target is a circular Sun-Synchronous Orbit
(SSO), 10:30 LTAN with an altitude of 523 km.
• Attitude: Nadir-pointing attitude has been selected as a
baseline for nominal operations.
• Mission profile: The identified orbit produces a cycle of
106 orbits in a week, about 15 orbit per day, in order to
complete the coverage of the selected areas of interest
(Europe and South Atlantic Anomaly). The definition of
the areas of interest was driven by the optical payload
and the scientific instruments requirements.
