Data combinations accounting for LISA spacecraft motion

Lisa Interferometer Sensitivity to Spacecraft Motion

A study has been performed to assess the sensitivity of the LISA interferometer to motion of the spacecraft (S/C) with respect to the proof mass. The results are presented as a functions of arm length and Fourier frequency. In addition different optical arrangements have been analysed and their effects on the cancellation of the spacecraft motion is discussed.

Time-delay analysis of LISA gravitational wave data: Elimination of spacecraft motion effects

LISA ~Laser Interferometer Space Antenna! is a proposed mission which will use coherent laser beams exchanged between three remote spacecraft to detect and study low-frequency cosmic gravitational radiation. Modeling each spacecraft as moving almost inertially, rigidly carrying a laser, beam splitters and photodetectors, we previously showed how the measured time series of Doppler shifts of the...

Effects Analysis of Frozen Conditions for Spacecraft Relative Motion Dynamics

The purpose of this rersearch is to analyze the effective application of particular earth orbits in dynamical modeling of relative motion problem between two spacecraft. One challenge in implementing these motions is maintaining the relations as it experiences orbital perturbations (zonal harmonics J2 and J3), most notably due to the Earth’s oblateness. Certain aspects of the orbital geometry c...
