Abstract:
1. An inter-mobile body carrier phase positioning device comprising: a first observation data acquisition section that acquires observation data that is observed in a first mobile body, wherein the first observation data acquisition section determines a phase accumulation value of a carrier wave of a satellite signal; a second observation data acquisition section that acquires observation data that is observed in a second mobile body, wherein the second observation data acquisition section determines a phase accumulation value of the carrier wave of the satellite signal; a satellite pair determination section that determines pairs of satellites used for carrier phase positioning; a carrier phase positioning section that (i) takes, between each of the pairs of the satellites determined by the satellite pair determination section, a single difference or a double difference between the observation data acquired by the first observation data acquisition section and the observation data acquired by the second observation data acquisition section, and (ii) determines relative positional relation between the first mobile body and the second mobile body by carrier phase positioning with the use of the single difference or the double difference of the observation data; and a regulating section that regulates an effect of the single difference or the double difference of the observation data, taken for each of the pairs, on positioning result, by using weights, wherein
