Positioning system and non-transitory storage medium

A non-transitory storage medium storing a positioning program for causing a computing device connected to a first positioning antenna, a second positioning antenna, and a third positioning antenna attached to a first oscillating body to execute an information processing method, wherein

• the information processing method includes,
• acquiring a first position measured by the first positioning antenna, a second position measured by the second positioning antenna, and a third position measured by the third positioning antenna,
• calculating a current attitude of the first oscillating body at the first position from a first vector from the first position to the second position and a second vector from the first position to the third position,
• modifying a first reference vector from the first positioning antenna to a first predetermined point in the attitude of the first oscillating body at a predetermined time according to the calculated current attitude of the first oscillating body at the first position,
• calculating a position of the first predetermined point in the current attitude of the first oscillating body by adding the modified first reference vector to the first position,
• acquiring a second predetermined point of a second oscillating body to which a fourth positioning antenna, a fifth positioning antenna, and a sixth positioning antenna are attached, the second predetermined point being calculated based on a fourth position measured by the fourth positioning antenna, a fifth position measured by the fifth positioning antenna, and a sixth position measured by the sixth positioning antenna in a current attitude of the second oscillating body, and
• calculating a current positional relationship between the first predetermined point and the second predetermined point by referring to a position of the first predetermined point and a position of the second predetermined point.
