Electric propulsion dissociates the launching orbit from the operational orbit.
This has several key benefits. It optimises launch strategy, adds flexibility in the launcher choice, reduces
overall launch cost and optimizes the range of operational orbits available. It also increases resolution,
revisit rate, coverage, link performance and lifespan as well as enabling deorbitation and collision avoidance.
Lower your altitude, gain x10 data downlink capability and x2
picture resolution. Increase your altitude, gain x2 coverage,
revisit rate and lifespan. After launch – or during the mission.
Do that quickly with our high thrust electric propulsion system.
Correct your inclination to maintain specific positions such as Sun
Synchronous Orbits (SSO) after your launch and/or throughout the
Optimise the repartition of your satellites in a few days with
phasing manoeuvres within a single plane.
Constellation & rideshare? This is possible with our system. With
its high thrust, you are able to change the local time of your orbits
in order to phase your constellation globally. This is the ultimate
way to decrease launch costs.
Propulsion can be used to compensate atmospheric drag. Add a few years
of lifetime to your constellation, and develop new high downlink/high picture
resolution missions in Very Low Earth Orbit (VLEO).
Deorbitation & Collision avoidance
Deorbite your spacecraft at the end of its mission to prevent further
space pollution and protect the safety of your spacecraft with collision
Flexible and cost-optimised launch
Pack your satellites in a rideshare with larger batches of satellites and then phase your
satellites optimally around the Earth. With competing solutions this maneuver can take years
but with the Exotrail high thrust electric propulsion system it can be done in months and at a
fraction of the launch costs. This also allows our customers to use any scheduled launch and
then correct their orbital position. Electric propulsion = launch flexibility.
Enhanced revisit rate & coverage
With orbit raising, you can develop high coverage telecommunication constellations or high
revisit rate earth observation constellations at 600-2000km altitude. This allows you to either
use less satellites for the same coverage – or double the coverage for the same number of
satellites. It can take only a couple of months to reach your operational orbit after launch –
competing solutions would require a year. Thrust matters.
Very high resolution imagery & high downlink capability
Operating at 300km vs. 600km has the following benefits : x2 picture resolution, x10
downlink capability. Our high thrust EP system allows you to reach operational altitude
quicker. You can also double the duty cycle of your payload compared to competing
solutions : at a given thrust level, we use less power for the propulsion system – so that you
can use more for your payload.
Space Debris Compliance & Collision safety
New regulations are being put in place – it will soon be mandatory to plan a solution for
deorbitation if you want to launch satellites in orbit. Above 500-550km, you need a deorbitation
solution to prevent the generation of space debris. Our system can deorbit your spacecraft at
the end of its life. You can also avoid collisions with our active system and guarantee
the safety of your constellation.
New Space Services
Asteroid mining, space tugs, in-orbit services, space surveillance, active debris monitoring,
in-orbit assembly… We believe all these missions are opportunities that will arise in the coming
years. For all of them, you need electric propulsion. Our vision is to become a leader in on-orbit
servicing – we are working on advanced concepts of small satellite vehicles equipped with our
system in order to deliver disruptive business cases in the future.
