Abstract
A satellite navigation system assistance server is configured to reply to client requests that include an indication of the client's location, and if an accurate location is included in the server request, the satellite navigation system assistance server computes which particular SBAS systems are observable to the requesting client, and in this case the satellite navigation system assistance server limits its replies to pertinent information for a more compact response message.
