Abstract
Methods and devices may request and provide assistance data from an assistance server to a receiver in a global navigation satellite system. A request for assistance data may include a preference list of navigation models suitable for the requesting receiver. Multiple preference lists for different navigation model types (e.g., orbit model, clock model, almanac model) may be included in a single list and/or data structure, or as multiple lists and/or data structures. An assistance server may receive and process the preference list, for example, by parsing and traversing the ordered list(s) for different navigation model types, in order to provide satellite navigation data to the receiver in accordance with suitable navigation models that are available at both the receiver and the assistance server.
