Original Abstract Submitted

Determine a GNSS based position malfunction and further estimate an own-ship position when determining that the GNSS position may be inaccurate. The system of this disclosure may use information either from any one or more of internal navigation systems and external information sources to determine whether a GNSS based position for the own-ship may be inaccurate and to provide a pseudo position for the own-ship as an independent position source. The system of this disclosure may determine the existence of the GNSS malfunction based on independent position information.
