To solve such a problem that it may be difficult to accurately estimate the amount of water vapor.SOLUTION: A water vapor observation device includes: a determination unit that determines whether or not a GNSS signal received by a reception device is used for estimating precipitable water according to the positional relationship between the reception device and a GNSS (Global Navigation Satellite System) satellite that transmits the GNSS signal at the time of reception of the GNSS signal by the reception device mounted on a moving body to receive the GNSS signal; and an estimation unit that estimates the precipitable water representing the amount of water vapor in the atmosphere on the basis of the GNSS signal received by the reception device or discards the estimated precipitable water according to the determination result from the determination unit.SELECTED DRAWING: Figure 9

    【課題】精度よく水蒸気量を推測することが難しいことがある。【解決手段】水蒸気観測装置は、移動体に搭載されGNSS(Global Navigation Satellite System)信号を受信する受信装置がGNSS信号を受信した際における、受信装置と、GNSS信号を送信するGNSS衛星との間の位置関係に応じて、受信装置が受信したGNSS信号を可降水量の推定に用いるか否か判断する判定部と、判定部による判断の結果に応じて、受信装置が受信したGNSS信号に基づいて大気中の水蒸気量を表す可降水量を推定する、または、推定した可降水量の廃棄を行う推定部と、を有する。【選択図】図9
