The purpose of the present invention is to provide a technique that makes it possible to appropriately utilize centimeter-level positioning in the automotive sector. The positioning device determines an individual positioning solution including a vehicle position, determines a floating solution including the vehicle position and a carrier phase offset, determines an integer value offset, determines a fixed solution including the vehicle position, and sets as a positioning solution any of the individual positioning solution, the floating solution, the fixed solution, and a non-positioning solution indicating that there is no solution. And the positioning error of the positioning solution is used as the positioning error of the vehicle position to be predicted according to each epoch. 本发明的目的在于提供一种技术，能在汽车领域中恰当地利用厘米级定位。定位装置求出包含车辆位置的单独定位解，求出包含车辆位置和载波相位偏置的浮点解，求出整数值偏置，求出包含车辆位置的固定解，将单独定位解、浮点解、固定解和表示解不存在的非定位解中的任一个设定为定位解，并将定位解的定位误差作为车辆位置的定位误差按照每个历元进行预测。
