Abstract
A wireless terminal has the enhanced performance in the attainability of successful search of GPS satellites based on the operation of a position data server. The server sets a GPS satellite search time longer than usual when station data pertinent to surrounding stations is below a prescribed level, when the distance between the wireless terminal and a communication station is beyond a prescribed distance, when the wireless terminal is in such a specific area as seashore, or when a reference station or the communication station is a repeater station. The server sends data of the longer search time to the wireless terminal via the communication station. Setting a GPS satellite search time longer than usual prevents the deviation of the ideal search timing, which enables the optimal search of GPS satellites, out of the search time set by the position data server.
