Abstract:
A satellite orbit data compressing method includes: determining a compression method of a parameter value on the basis of a variation tendency of the parameter value in an orbit model approximating a satellite orbit; and calculating a compressed parameter value by reducing a bit sequence representing the parameter value using the determined compression method.
