METHOD FOR DETERMINING CO-ORDINATES OF SATELLITE

摘要

PURPOSE: A method for determining the co-ordinates of a satellite is provided to reduce a calculating time and cost for determining the current values of the orbital position of an artificial satellite. CONSTITUTION: A satellite co-ordinates is determined at given nodal points of the orbit which are spaced from each other by a predetermined time interval and also the velocity of the satellite is determined at additional nodal points. The velocity and co-ordinates of SRNS(Satellite Radio Navigation System) GLONASS satellite at the nodal points of the orbit are determined through a calculation algorithm and a Taylor's sixth-order polynomial. The satellite co-ordinates at points located between the nodal points is determined through a Taylor's second-order or third-order polynomial. The coefficients of the polynomials are determined by the co-ordinates and velocity at the nodal points.
