small platform for CubeSats, but actually not having a CubeSat
two CubeSat frictionless platform ideas quite different than in other older articles
one is without air-bearing, but introduces automatic torque compensation, with nice analysis of its performance
second gives a radical approach, with a minimal satellite container, which in theory provides full 3 DOF and minimal parasitic MOI additions, however it seems to be very challenging to realize in practice
interesting approach with porous static part of air bearing, instead of regular that have only several outlets
automatic COG and MOI calibrations, possibility to simulate big range of MOI configurations with moveable weights and applying scaling factors to the output control
