Validation with SLR GRACE-A GRACE-B Reduced-Dynamic Orbit FGS Workshop 2004, Höllenstein/Wettzell, October 27 - 29, 2004 Reduced-Dynamic Orbit Kinematic Orbit Kinematic Orbit Day of year Day of year Day of year
FGS Workshop 2004, Höllenstein/Wettzell, October 27 - 29, 2004 Reduced-Kinematic POD Kinematic POD with dynamic information in order to reduce influence of weak geometry and phase breaks (jumps). Methods: • Absolute constraints to the a priori orbit • Relative constraints between epochs • Gauss-Markov process Normal system solution: • Full normal matrix inversion (86400 kinematic coordinates for one-day arc) • L - U factorization (block tridiagonal system), block forward elimination and back substitution. Characteristics: Smoothing effect
