1. An apparatus comprising:
an inlet connected to a propellant source that contains propellant at a first pressure;
a pressure regulator having an upstream side connected to the inlet and a downstream side, the pressure regulator configured to reduce propellant pressure from the first pressure at the inlet to a second pressure at the downstream side;
a manifold connected to the downstream side of the pressure regulator such that the propellant from the pressure regulator fills the manifold at the second pressure, the manifold including a plurality of manifold outlets;
a plurality of gas lines, each gas line extending from a corresponding manifold outlet, each gas line terminating at a corresponding connector that has features configured for connection to corresponding features of a fill valve of a corresponding satellite propellant tank that is located in a corresponding satellite; and
a plurality of satellites, each satellite having a satellite propellant tank with a fill valve connected to a corresponding connector.
