We are at the brink of a new era - the era of satellite constellations. These are very large satellite clouds of several tens up to several thousand satellites flying in LEO. This is only possible if each individual constellation satellite is small and relatively cheap. Hence, equipping a constellation satellite requires simpler and cheaper systems, which is also the case for propulsion system. This calls for component and sub-system production approach in a non-traditional manner with elements of mass production.
The severe cost limitation might also impose limitations on the total number of propulsion systems while still having to guarantee the targeted thrust capabilities, not only in performance, but also in thrust direction. These problems are met with the solutions under developement at Sparc Industries sarl.

On the video one can see simulated neutral gas inside the thruster. On the right hand side cold gas is entering the thruster. The thrust direction of the thruster is towards the left and one can see that with the gas moving towards the exit of the thruster the velocity in the thrust direction increases, which can be seen by colour change of the particles from red to yellow. And thus providing for the thrust of the thruster.
