The Garnet propellant measurement unit combines pressure and temperature sensing as well as the signal conditioning electronics. Designed as a seamless plug-and-play subsystem, it serves the critical function of assessing propellant levels from tank pressure and temperature throughout the lifecycle and particularly at end-of-life stages. The unit comes in multiple configurations ensuring compliance to common satellite propellants, fluidics and avionics interfaces.
