Abstract
A system, method, and apparatus for advanced timing and time transfer for satellite constellations using crosslink ranging and an accurate time source are disclosed herein. In particular, the present disclosure relates generally to systems for providing improved positioning, navigation, and/or timing information for oscillator calibration and more specifically, to use at least one satellite with accessibility to an accurate time source to calibrate the local oscillator on a crosslink paired satellite. In at least, one embodiment, time synchronization on a subset of satellites with crosslinking capabilities is used to distribute time through a network of crosslinked satellites.
