    • From a single transmitted from a satellite, are extracted a position where a terrestrial station side system exists and a position of the satellite. A distance between the terrestrial station side system and the satellite, based on a difference of those positions. Then, a sum of the distance between the terrestrial station side system and the satellite and a distance between the satellite and a mobile station side system, based on a difference between the reception time when a mobile station side communication antenna receives the signal and the transmission time. Further, the distance between the mobile station side system and the satellite is obtained by subtracting the distance between the terrestrial station side system and the satellite from the obtained sum. And, based on the distance between the mobile station side system and the satellite, the position where the mobile station side system exists is obtained.
    • 从卫星发射的单个卫星中,提取出地面站侧系统存在的位置和卫星的位置。 基于这些位置的差异,地面站侧系统与卫星之间的距离。 然后,基于移动站侧通信天线接收到信号的接收时间与传输之间的差异,地面站侧系统与卫星之间的距离与卫星与移动站侧系统之间的距离之和 时间。 此外,通过从获得的和减去地面站侧系统和卫星之间的距离来获得移动站侧系统与卫星之间的距离。 并且,基于移动站侧系统与卫星之间的距离,获得移动站侧系统存在的位置。
