Abstract
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.
