There is provided a method for assisting in providing a first fix in a global positioning satellite system, the method comprising: storing of connection point association data for a network connection point, observed by a portable electronic device, for subsequent use in assisting in providing a first fix, the connection point association data providing for approximation of the position of a device at the observed network connection point by associating together connection point identifiers of the observed network connection point and one or more other network connection points to allow for positional data used for determining the position at one or more other network connection points to be used for the approximation of the position of the device at the observed network connection point.
