POSITIONING DEVICE, INTEGRATED CIRCUIT DEVICE, ELECTRONIC DEVICE AND PROGRAM

PROBLEM TO BE SOLVED: To provide a positioning device, an integrated circuit device, an electronic device and a program that enable improvement in positioning accuracy.SOLUTION: A positioning device 1 includes: a first positioning part 10 that performs a first positioning process of performing positioning on the basis of a radio signal; an autonomous positioning sensor 20 that detects a status of the positioning device 1; a second positioning part 30 that performs a second positioning process of performing positioning on the basis of an output of the autonomous positioning sensor 20; a posture determination part 40 that determines whether or not a posture of the positioning device 1 changes on the basis of the output of the autonomous positioning sensor 20; and a correction part 50. When the posture determination part 40 determines that the posture of the positioning device 1 changed at first time at a position between a first point and a second point, the correction part 50 performs a correction process with respect to a movement direction to be calculated from a series of position data to be acquired after the first time. 【課題】測位精度を向上できる測位装置、集積回路装置、電子機器及びプログラムを提供すること。【解決手段】測位装置１は、無線信号に基づいて測位する第１測位処理を行う第１測位部１０と、測位装置１の状態を検出する自律測位センサー２０と、自律測位センサー２０の出力に基づいて測位する第２測位処理を行う第２測位部３０と、自律測位センサー２０の出力に基づいて、測位装置１の姿勢が変化したか否かを判定する姿勢判定部４０と、補正部５０と、を含み、補正部５０は、第１地点から第２地点までの間の位置で、第１時刻に測位装置１の姿勢が変化したものと姿勢判定部４０が判定した場合に、第１時刻の後に取得される一連の位置データから算出される移動方向に対して補正処理を行う。【選択図】図１
