    • PROBLEM TO BE SOLVED: To provide a system and method for quickly determining a position of a user terminal (for example, a mobile phone) in a satellite communication system such as a low-earth-orbit satellite communication system, using only one satellite. SOLUTION: The present invention provides the system and method for determining the position of the user terminal (for example, a mobile wireless phone) in the low-earth-orbit satellite communication system 100. The system comprises the user terminal 106, at least one satellite 104 with a known position and a known velocity, and a gateway 102 (that is, a ground base station) for communication with the user terminal 106 through the satellite 104. The method includes the steps of determining a range parameter (802) and determining a range rate parameter (806). The range parameter represents a distance between the satellite and the user terminal. The range rate parameter represents a relative radial velocity between the satellite and the user terminal. The position of the user terminal on the earth surface is determined based on the range parameter, the range rate parameter, and the known position and velocity of the satellite (810).
