This work describes stiffness estimation for new large-sized (with aperture more than 50 m) umbrella space reflector. Reflector stiffness is measured by natural frequencies. Mode shapes and respectively natural frequencies are calculated by finite element method. First four natural frequencies with respectively mode shapes are presented.
