    • An information processing apparatus includes an acquiring unit configured to receive signals, which are transmitted from a fixed station, including identification information for identifying the fixed station, measure receive signal strength indications of the received signals, and acquire position information indicating positions at which the receive signal strength indications are measured, the receive signal strength indications, and the identification information in association with each other; and a gain/attenuation rate calculating unit configured to calculate correction information including a transmission antenna gain in a specific direction from the fixed station and an attenuation rate in a propagation path, the correction information being obtained from the receive signal strength indication measured at a first distance in the specific direction from the fixed station and the receive signal strength indication measured at a second distance in the specific direction that is different from the first distance.
    • 一种信息处理装置,包括:获取单元,被配置为接收从固定站发送的信号,包括用于识别固定站的识别信息,测量接收信号的接收信号强度指示,以及获取指示接收到的位置的位置信息 测量信号强度指示,接收信号强度指示和识别信息相互关联; 以及增益/衰减率计算单元,被配置为计算包括来自所述固定站的特定方向上的发送天线增益和所述传播路径中的衰减率的校正信息,所述校正信息从在第一处测量的接收信号强度指示获得 距离固定站的特定方向的距离和在与第一距离不同的特定方向上的第二距离处测量的接收信号强度指示。
