NASA's Small Spacecraft Body of Knowledge - CMGs
« on: April 18, 2017, 03:53:30 PM »
I visited NASA's new SSBK website and read section #5 on GNC.  Interestingly, Control Moment Gyros were not mentioned anywhere in that section.  Since CMGs are not good at high accuracy pointing (yet), I can only speculate that they were omitted since they are typically not chosen for space missions where accurate pointing is required.

This knowledgebase will be in constant flux, so I expect this to change in the future.
