Moving Information Determination Apparatus, a Receiver, and a Method Thereby

摘要

A moving information determination apparatus includes an ECA (Earth Center Assistant) information acquisition module, an altitude information and position information storage module and a moving information calculation module. The altitude information and position information storage module provides initial position information of the moving information determination apparatus and altitude information of the moving information determination apparatus. The ECA acquisition module obtains a radius of the Earth at the current position of the moving information determination apparatus. The moving information calculation module calculates the current position and/or velocity of the moving information determination apparatus based on the radius of the Earth and a plurality of signals from a plurality of satellites.
