•Capacitance read-out at room temperature: sensitive, reliable, well known
•Fast spin makes many perturbing effects DC (constraints on payload and s/c released)
•Ground testing  of  FULL  payload prototype possible !!!!
•2-axis sensitivity (in the plane perp. to symmetry axis): maintains 2 DOF of signal; allows supercritical rotation (Þ self-centering + high frequency modulation); improves sensitivity by factor Ö2  w.r.t  having only one  sensitive axis
