Interested in the benefits that CMGs could bring to your mission (and the trade-offs too, of course) - take a look at this satsearch resource on the topic:
Control moment gyroscopes (CMGs) are one of the newer classes of attitude actuator to be used on microsatellites and larger CubeSats in recent years, and the supply chain for them is developing well. They consist of a spinning rotor fixed to motorized gimbals that are used to alter the rotor’s orientation and thus change its angular momentum, producing torque. This torque acts on a satellite to change its attitude in orbit, or to counteract attitude changes caused by external forces. This is similar in function to a reaction wheel of course, however a CMG can produce torque in any direction whereas a reaction wheel is in a fixed position and can produce it in one direction only. This means that although CMGs are heavier and take up more volume than a reaction wheel, to deliver the same amount of torque, you only need one system (if gimballed correctly) to replace multiple reaction wheels. Several companies, including satsearch Trusted Suppliers Tensor Tech and VEOWARE SPACE, have brought to market CMGs that are designed to maximize torque output with a minimal SWaP budget, and they can also work well when used in conjunction with reaction wheels, or even multiple CMGs for larger systems and more complex mission needs. Take a closer look at this technology in our overview here: https://lnkd.in/eAuk-Zxu - and let us know if you need support sourcing attitude actuators for your next mission ?? Ad astra!
