(57) Abstract :
A mobile Communications device uses a method for determining position that involves a positioning filter, such as a Kalman filter,
which is initialized with measurements from reference stations such as satellite vehicles and/or base stations which may be acquired
during different epochs. Accordingly, the positioning filter may be used for position estimation without the need to first acquire at
least three different signals during the same measurement epoch.
