Abstract
The object is to provide a technology for appropriately making the centimeter positioning available in automotive applications. A positioning apparatus determines a standalone positioning solution including a vehicle position, determines a float solution including the vehicle position and a carrier phase bias, determines an integer ambiguity, determines a fix solution including the vehicle position, sets any one of the standalone positioning solution, the float solution, the fix solution, and a non-positioning solution indicating no existence of a solution as a positioning solution, and predicts a positioning error of the positioning solution as a positioning error of the vehicle position per epoch.
