Global autonomous determination method of meridian locations involves determining meridian of unknown location by changing known meridian congruent at specified angle in clockwise direction

摘要

The local meridian representation of inertial sight is determined by comparing year angle epsilon =we*tx/365 and day angle iota =wetx. The unknown meridian location P' is determined by changing the known meridian congruent at time tx+n delta t by an angle wmn delta t in clockwise direction, taking into consideration the known zeroth meridian position at time tx or tx+n delta t to state terrestrial longitude of location. The year and the day angles are shifted relative to an inertial reference angle R', at a time interval delta t multiplied by high simulation angular velocity wm, until both the angles become congruent.
