Abstract:
A method for updating a set of transformation information parameters used in a global navigation satellite system includes: obtaining at least one satellite navigation information for a satellite; and updating the set of transformation information parameters according to the obtained satellite navigation information. The method can extend the life time of the set of transformation information parameters, and used to generate better predictions of the satellite trajectory therefore the TTFF can be reduced while the positioning accuracy can also be improved.
