<p>The method involves calculating pseudo distances between a mobile device (20) e.g. portable telephone, and satellites (S01-S04), and encapsulating distances with date (DE) at which the distances are calculated. The distances and date are transmitted by a radio station (300) towards an assistance server (500) that estimates time bias between common clock of the satellites and clock of the station based on distances and the date. - Independent claims are also included for the following: - (A) an assistance server for improving acquisition of satellite data by a mobile device - (B) a method for improving acquisition of satellite data by a mobile device - (C) a method for calculating position of a mobile device - (D) a mobile device comprising a radionavigation satellite system receiver in an asynchronous cellular telephony system.</p> |
