Exotrail releases a new version of ExoOPS™

The last release of ExoOPS™ - Mission Design (v2.4.0)

These missions allow to design and optimise constellations of satellites and to run parametric studies on Attitude Dynamics Control Systems of propulsion-equipped spacecrafts.

Available as a Software as a Service (SaaS), ExoOPS™ - Mission Design v2.4.0 brings the following improvements:


This new functional module allows to take constellation studies one step further. It offers automated ways to generate and optimise constellation geometries. It also features a constellation simulator that can propagate a constellation of satellites, taking perturbations into account, and gather precise ephemerides of all visibility events. This module is composed of three new missions:

  • Generation: automatically generate a constellation that reaches a given level of performances on a given area of interest.
  • Optimisation: optimise the performances of a constellation by modifying its geometry, under given constraints.
  • Simulation: propagate and visualize all the spacecrafts of a constellation in a single simulation.


  • ADCS Design mission: carry out a preliminary design of the ADCS (Attitude Dynamics Control Systems) of a spacecraft subject to perturbations including drag, solar radiation pressure, residual magnetic moment and a misalignment between its centre of gravity and the thrust direction of its propulsion system.


  • Attitude transition simulation: take spacecraft agility into account to simulate the transitions between attitude modes during a simulation.
  • RF antenna & payload simulation: evaluate actuator performances for satellite design trade-off by measuring their impact on the electrical power budget.


  • More contextual help improvements for a more user-friendly experience.

All new features can be found under the ExoOPS™ - Mission Design changelog!

ExoOPS™ is Exotrail’s cloud-based software dedicated to space mission simulation and operations. It is used by commercial and institutional customers such as CNES (the French Space Agency), Eutelsat, Thales Alenia Space and many others. ExoOPS™ supports satellite operators, satellite manufacturers, space agencies and launch service providers throughout their mission lifecycle, from preliminary design to satellite deployment, through to in-space operations. ExoOPS™ offers a complete and powerful flight dynamics environment, dedicated to constellations of propelled satellites.

Within ExoOPS™ software suite, ExoOPS™- Mission Design is a custom-designed and built operational software for mission analysis and flight dynamics – with an emphasis on propulsion. It is cloud-based, user friendly and gives users unique insights into mission analysis and propulsion planning. It allows constellation designers, flight dynamic engineers, system engineers and control centre operators to meet the challenges of designing, building and launching constellations of satellites.

With ExoOPS™ - Mission Design, you can quickly and easily:

  • Create and optimize constellation design.
  • Understand and identify the best strategy to deploy satellites into orbit.
  • Perform quick trade-offs on satellite performances.
  • Simulate maneuvers along a specific satellite mission.
