Abstract

システムに要求される測位精度と、前記拡散符号列の受信間隔の検出精度に応じて基地局どうしのクロック速度比検出の分解能を決定することのできる移動局測位システムおよび移動局測位方法を提供する。 受信間隔算出部８２（ＳＡ１）により、基準基地局が符号数（符号間隔）を決定して１回発信し各普通基地局が受信した拡散符号列における２つの拡散符号列内の拡散符号の受信間隔が算出され、クロック速度比算出部５４（ＳＡ２）により各普通基地局と基準基地局とのクロック速度比が算出され、時計ずれ算出部５６（ＳＡ３）により基準基地局の時計に対する各普通基地局の時計の時刻ずれが算出され、受信時刻補正部５８（ＳＡ４）により、各普通基地局における移動局からの電波の受信時刻が基準基地局の時計を基準とする時刻に補正され、測位部６０（ＳＡ５）により補正された受信時刻を用いた移動局の測位が行われる。
