About
Busek’s BET-MAX precision reaction control system provides high-resolution control via electrospray propulsion technology. Up to four 125 cm³ BET-300P thrusters per centralized PPU can be positioned as desired to provide attitude or orbital control on platforms as small as 3U, with throttled continuous thrust from under 1 µN up to 150 µN and sub-µN resolution. Each module includes propellant storage sufficient for over 100 N·s of impulse plus all feed components. Spacecraft charge neutralization uses Busek’s patented, flight-qualified Carbon Nanotube Field Emission Cathode (CNTFEC). Applications include ultra-precise pointing, reaction wheel desaturation, formation flight, LEO drag compensation, and precision pointing for exoplanet observation and laser communications.
