Abstract
A clock error prediction method includes: obtaining historical satellite clock error data of a preset time period which includes broadcast ephemeris clock error data and precise ephemeris clock error data; obtaining corrected precise ephemeris clock error data based on the broadcast ephemeris clock error data; obtaining a single-day clock speed of each satellite through fitting based on single-day clock error data in the corrected precise ephemeris clock error data of each satellite; obtaining a clock speed time sequence of each satellite based on the single-day clock speed of each satellite; obtaining a clock speed change rate of each satellite through fitting based on the clock speed time sequence of each satellite; and obtaining a predicted clock error of each satellite in a preset future time period based on an initial clock error value, a clock speed, and the clock speed change rate of each satellite.
