Micro Cathode Arc Propulsion Module
Quick Overview
The Micro Cathode Arc Propulsion Module is a critical subsystem for orbit maintenance and attitude control of micro- and nano-satellites. It utilizes solid propellant and does not require a dedicated propellant feed system. The module supports long-term storage and features extremely low impulse bit (in the μN·s range), high efficiency, low mass, and simple structural design. It can be easily modularized and adapted for various missions, operating at low discharge voltages. The propulsion performance can be tuned through flexible control of the discharge frequency, making it suitable for precision satellite attitude control applications.
