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 Kane's method.
Efficient computer simulations were achieved by developing a FORTRAN program
and using Dynamic Simulation Language ( DSL ).
