Positioning device, positioning method, and positioning program
By receiving satellite signals in multiple frequency bands and comparing parameters to detect spoofing, the positioning device ensures accurate positioning by excluding spoofed signals, addressing the issue of reduced satellite availability and accuracy due to interference.

Abstract
To provide a positioning device that can reduce the risk of decreased positioning accuracy in an environment of spoofing attacks. [Solution] A positioning device comprising: a receiving unit that receives a first satellite signal in a first frequency band and a second satellite signal in a second frequency band different from the first frequency band transmitted from a first satellite; a positioning unit; a determination unit that compares the value of a predetermined parameter included in the first satellite information of the first satellite based on the first satellite signal with the value of the predetermined parameter included in the second satellite information of the first satellite based on the second satellite signal to determine whether or not the first satellite is spoofed; and a control unit that controls the positioning unit so as not to perform positioning using the first satellite information and the second satellite information of the first satellite when the determination unit determines that the first satellite is spoofed.
