Global navigation satellite system (GNSS ) trajectory prediction method for mobile apparatus e.g. smart phone, involves propagating set of satellite trajectory extension data by using estimated satellite trajectory prediction model

摘要

The GNSS trajectory prediction method involves obtaining a satellite navigation message via a receiver (20) and then determining a propagating condition according to the obtained satellite navigation message. An input/output (I/O) interface (32) is used to obtain a satellite navigation message. The parameters of a satellite trajectory prediction model is estimated according to the propagating condition which is determined via a microprocessor (35). A set of satellite trajectory extension data is propagating by using the estimated satellite trajectory prediction model. An independent claim is also included for a GNSS trajectory prediction device.
