Abstract
In this paper, we describe a hybrid-extended Kalman filter algorithm to synchronize the clocks and to precisely determine the interspacecraft 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.
