Abstract
A positioning method whereby inertial positioning data is calculated based upon measurements of an Inertial Navigation System. Virtual satellite ranging data is then generated based upon the inertial positioning data. The virtual satellite ranging data is then combined with received satellite ranging data from one or more satellites forming part of a Global Navigation Satellite System (GNSS). A GNSS positioning solution is then calculated based upon the combined received satellite ranging data and the virtual satellite ranging data.
