The invention relates to a solid or liquid propellant () tank () for a thruster, the tank () comprising means for forming a gas () in the tank, the tank () having an opening () of surface area S for the extraction of a flow () of the propellant gas from the tank (). According to the invention, the tank () comprises a propellant gas flow on-off control system comprising a grid () arranged opposite the opening () of the tank (), a first thermal regulation system () for heating the gas () in the tank and a second thermal regulation system () for heating the grid (), said grid () including holes of total surface area greater than the surface area S of the opening of the tank ().

Disclosed is a space cold gas thruster operating with a solid propellant. The cold gas thruster includes a tank suitable for containing a solid propellant and a tank heating device suitable for sublimating the solid propellant and forming gaseous propellant, the tank having an aperture for transferring the gaseous propellant outside the tank, such as a nozzle. Also disclosed is a process for determining the amount of remaining propellant in the propellant tank of the disclosed cold gas thruster.
