GG: main novelties and advantages (II)
Capacitance read-out at room temperature: sensitive,
reliable, well known
Fast spin makes many perturbing effects DC (constraints
on payload and s/c released)
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
Ground testing  of  FULL  payload prototype possible !!!!
