FIELD: radio engineering, communication.
SUBSTANCE: steps are executed for providing modified format Global Navigation Satellite System (GNSS) Sensitivity Assistance (SA) information derived from predicted GNSS signal data according to a type of GNSS system, the type of GNSS system having a native formatting for GNSS signals, which has certain characteristics and the modified format GNSS SA information has the predicted GNSS signal data encoded without one or more of the characteristics used in the native formatting, and sending the modified format GNSS SA information over a communication link from a location server for a mobile station having a GNSS receiver capable of receiving and decoding native formatted signals according to the type of GNSS system.
EFFECT: providing assistance information signals, high sensitivity, associated with one or more positioning systems, and high sensitivity of the receiver due to prediction of Global Navigation Satellite System signal data.
