According to the scheme in chapter 3, experimental investigations are conducted on the single-axis air-bearing test bed. The effects of both rotating speed and air damping on the vibration frequencies of the beam are discussed. The phenomenon of dynamic stiffening is verified by the results of experiment.

Both viscous damping and air drag force must be introduced into the dynamic models. The experiment is carried out in the single-axis air-bearing test bed according to the experiment scheme in chapter 3. The results demonstrate the validity of the developed model, while the conventional zero-order approximate approach could lead to bad results for some high speed cases.

The Bernese 5.0 software is used to compute the precise orbits of the FORMOSAT-3 and GRACE satellites using the kinematic and reduced-dynamic methods based on zero-differenced GPS phases from these two satellites missions. This study concentrates on the effects of satellite attitude, GPS antenna phase center variation and center of mass.
