Missions

Image
  • Launch of microsatellites (>150 kg)
  • Launch of microsatellite rideshare (<150 kg)
  • Keeping satellite constellations in operational condition by replacing faulty satellites
  • Participation in Earth orbit clean-up programs
  • Integration with defense systems to guarantee the safety of the French space ecosystem

HPS will offer the best solution to set a quick mission in LEO. It will carry satellites to any specific LEO in a matter of days. Individual mission, constellation completion, cubesatellites rideshare, everything is possible.

Innovation

Today, the space industry uses two propulsion technologies: solid propulsion and liquid propulsion. However, both are only a compromise of ideal criteria. A third propulsive launcher technology exists: hybrid propulsion. This technology consists of injecting one of the propellants in liquid form into a combustion chamber which contains a second propellant in the solid state.

The thrust is modulated by controlling the amount of liquid propellant injected into the combustion chamber. This technology enables the payload orbit to be accurately set. Despite numerous advantages, this technology is only rarely used because of a technological obstacle: its performance decreases with the increased size of the thruster.

That's why HPS chose to develop a technological key to unlock its full potential. With this innovation, hybrid propulsion becomes the most advantageous propulsion system among existing technologies.
