Abstract:

The Navy Remote Ocean Sensing System N-ROSS satellite is being developed to supply accurate data on ocean parameters for fleet operations. a Low Frequency Microwave Radiometer LFMR, a large flexible reflector attached to an angled flexible boom, is a sea surface temperature sensor on this satellite which rotates at 15 RPM. The dynamic interaction between the reflector and the boom, and the effects of the reflector orientation and flexibility on the pointing error of the LFMR during a spin-up procedure are investigated by performing dynamic simulations. Dynamical equations of this flexible multibody system are formulated using Kanes method. Efficient computer simulations were achieved by developing a FORTRAN program and using Dynamic Simulation Language DSL.
