Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 9:
10. A non-transitory computer-readable recording medium in which a moving body positioning program is recorded, the moving body positioning program causing a computer to execute:
processing of acquiring observation data that is acquired from a GNSS signal transmitted from each of one or more satellites and received by a GNSS receiver included in a moving body and that is observation data corresponding to each of the satellites,
processing of acquiring external data that is predetermined data other than the observation data,
processing of detecting multipath, with respect to an observation data group that is a set of pieces of the observation data respectively corresponding to the satellites, by determining whether each piece of the observation data in the observation data group is the multipath on the basis of a blocked range with respect to the GNSS signals in the moving body or an observation status of the GNSS signals in a different station that is a receiver station other than the moving body, the blocked range or the observation status being acquired by an analysis of the external data, and
processing of performing positioning calculation after selection of a satellite to be used and a satellite to be excluded on the basis of a result of the multipath detection,
wherein, in the processing of detecting the multipath, the moving body positioning program causes the computer to execute:
assigning, to at least observation data included in the observation data group and determined to be the multipath, a predetermined index to be a determination condition for invalidity of the observation data.
