ABSTRACT:
A method for searching satellites includes obtaining a position information, obtaining a time information, calculating a regional range according to the position information, finding out numbers of target satellites corresponding to the time information and within the regional range from ephemeris data in an ephemeris database, searching the target satellites corresponding to the numbers, and receiving the satellite signals from each searched target satellite. In an electronic device capable of searching satellites, an operation interface is used to output the position information, and a calculation unit is used to calculate the regional range according to the received position information. A look-up unit is electrically connected to the ephemeris database, and used to find out the numbers of the target satellites corresponding to time information and within the regional range from the ephemeris data.
