Abstract

課題　短時間で基地局間の時刻の補正を行うことのできる移動局測位システムを提供する。 解決手段　受信間隔算出部８２（ＳＡ１）により、基準基地局１１が１回発信し各普通基地局１２が受信した拡散符号列における２つ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１２における受信間隔と基準基地局１１による２つの拡散符号の発信間隔とに基づいて各普通基地局１２と基準基地局１１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１１の時計４４に対する各普通基地局１２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１２における移動局１０からの電波の受信時刻が基準基地局１１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１０の測位が行われる。
