Frequently Asked Questions
Common questions about Tiny Ultra-High-Pressure Cold-Gas Propulsion System
How does the Tiny Cold-Gas Propulsion System work with momentum wheels for fine attitude control, considering potential wobble?
Our system is designed to complement momentum wheels for precise attitude control. While momentum wheels handle larger attitude adjustments, our cold-gas thrusters counteract accumulated momentum and address issues like nutation (wobble). Precisely timed pulses from the thrusters dampen oscillations, ensuring stable pointing. This synergy improves overall agility and pointing accuracy, especially crucial for applications like high-resolution imaging or laser communication.
