METHOD AND APPARATUS FOR UPDATING AND PROVIDING SATELLITE NAVIGATION MESSAGE

摘要

Aspects of the disclosure include a method for sharing satellite navigation messages. The method includes receiving a download report from a receiver. The download report indicates what portions of a satellite navigation message are currently stored by the receiver. The method also includes determining whether to update a satellite navigation message database associated with a server based on the portions of the satellite navigation message stored by the receiver. In response to determining that the satellite navigation message database should be updated, the method further includes requesting the receiver to transmit a subset of the satellite navigation message currently stored by the receiver to the server; receiving the subset of the satellite navigation message; and updating the satellite navigation message database associated with the server based on the received subset of the satellite navigation message.
