A method may perform assisted position determination based on pressure measurements which includes ascertaining a pressure value, and determining whether the ascertained pressure value is within a first threshold of a stored pressure value of the set of stored position and pressure values. The method may also include obtaining a stored position value, from the set of stored position and pressure values, which corresponds to the stored pressure value, in response to determining that the ascertained pressure value is within the first threshold of the stored pressure value, and providing the stored position value as a current location along the route.
