METHOD OF UPDATING GPS ALMANAC DATA FOR SATELLITES NOT IN VIEW

摘要

A method of updating Global Positioning System almanac data includes steps for obtaining a current satellite almanac for a satellite constellation at a server in a communications infrastructure associated with a wireless device ( 102 ), creating a subset of the current satellite almanac in the server that includes satellite almanac data only for fewer than all satellites listed in the current satellite almanac ( 104 ), and transmitting the subset of the current satellite almanac from the server to the wireless device ( 106 ).
