Abstract
A method for unifying a time in a wide area of space, and a space time-keeping system. The method comprises: establishing a wide-area inertial coordinate system, wherein the wide-area inertial coordinate system comprises all local area coordinate systems within a space range covered by a unified time (S); obtaining an original local time, and establishing a local orbital parameter ephemeris by using the original local time as a time independent variable (S); observing a pulse profile of a pulsar according to the original local time, and determining a local pulse time, wherein the local pulse time is a coordinate time when a pulse of the pulsar arrives at a local moment (S); and converting the local pulse time by using the local orbital parameter ephemeris, so as to obtain a pulse origin time.
