Abstract:
In this paper, we describe a hybrid-extended Kalman filter algorithm to
synchronize the clocks and to precisely determine the inter-spacecraft
distances for space-based gravitational wave detectors, such as (e)LISA.
According to the simulation, the algorithm has significantly improved the
ranging accuracy and synchronized the clocks, making the phase-meter raw
measurements qualified for time- delay interferometry algorithms.
