How EON flies your satellite.
From integration on the ground to an avoidance manoeuvre executed in orbit — four phases, no ground pass required in between.
One change onboard.
Four consequences on the ground.
Move the flight dynamics onboard, and the rest of your operations change with it
Onboard Navigation and Collision Avoidance
EON determines its own orbit, assesses conjunction risk, and plans its own manoeuvres with minimal ground station intervention.
Minimized ground workload
Routine orbit determination and manoeuvre planning leave the ground team. They supervise the fleet instead of running the loop for every satellite.
Efficient propellant use
Fresh measurements, onboard. Reduced number of false positives, relative OD with other secondaries: fewer maneuvers, when they matter.
Scale with the fleet
Satellites share orbit data peer-to-peer, so accuracy improves as the fleet grows. Going from five satellites to fifty multiplies the operations, not the operators.
Navigation onboard
EON determines its own orbit, plans its own manoeuvres and assesses conjunction risk directly on the spacecraft — no ground station in the routine loop.
No ground pass to wait for
A conjunction is handled when the risk appears, not when the next contact window allows.
Less ground workload
Routine orbit determination and manoeuvre planning leave the ground team. They supervise the fleet instead of running the loop for every satellite.
Less propellant burned
The onboard camera refines the secondary object's orbit and cuts false positives, so fewer avoidance manoeuvres are executed.
Scales with the fleet
Satellites share orbit data peer-to-peer, so accuracy improves as the fleet grows. Going from five satellites to fifty multiplies the operations, not the operators.
