Abstract
The inter-mobile body carrier phase positioning device according to the invention includes: a first observation data acquisition means that acquires observation data concerning a phase accumulation value observed in a first mobile body; a second observation data acquisition means that acquires observation data concerning a phase accumulation value observed in a second mobile body; a satellite pair determination means that determines pairs of satellites used for carrier phase positioning; and a carrier phase positioning means that takes, between each of the pairs of the satellites determined by the satellite pair determination means, a single or double difference between the observation data acquired by the first observation data acquisition means and the observation data acquired by the second observation data acquisition means, and determines relative positional relation between the first mobile body and the second mobile body by carrier phase positioning using the single or double difference of the observation data.
