FORMOSAT-5 Cold Gas Propulsion System

STI has handed over the Cold Gas Propulsion Subsystem to NSPO after successful integration and verification test. The new developed thrusters from AST were qualified by STI for FORMOSAT-5.

Details on the Cold Gas System

  • The Cold Gas Propulsion Subsystem is used for orbit maintenance and attitude control, using nitrogen as propellant.
  • The subsystem contains one high pressure tank carrying the necessary amount of nitrogen. The pressure reduced by the pressure regulator is fed into two independent branches.
  • Each of these branches consists of two thrusters and one latch valve allowing to shut-off each branch in case of propellant leakage.

FORMOSAT-5 launch

FORMOSAT-5 has been successfully launched on the 24th of August 2017 from Air Force Base Vandenburg on a Falcon 9 (SpaceX). This is a major milestone both for NSPO as being the first earth observation satellite being designed by Taiwan and for STI as a provider of cost efficient high quality satellite systems.
