1. A portable measurement device that is moved to disposition locations of a plurality of apparatuses disposed in different locations from each other, is connected to any of the apparatuses of a moving destination, and then performs reception processing on desired signals in a plurality of frequency bands, among signals in frequency bands, which are different from each other, transmitted from a global navigation satellite system (GNSS) satellite that configures any GNSS, as a multi-band, and performs measurement on the apparatus of the moving destination based on information on a position or time acquired by the reception processing, the measurement device comprising:
an antenna input terminal capable of connecting a GNSS antenna that receives a signal transmitted from the GNSS; and
one or more processors collectively configured to:
selectively set the GNSS, which is a transmission source of the signals in the plurality of frequency bands corresponding to the multi-band;
detect a reception abnormality in the signals in the plurality of frequency bands corresponding to the multi-band based on reception signal information obtained by the reception processing on the signal transmitted from the selectively set GNSS, which is the transmission source, in a state in which the measurement device is connected to any of the apparatuses of the moving destination and the GNSS antenna is connected to the antenna input terminal;
notify a user of an alert notification that a multi-band reception abnormality occurs when the reception abnormality is detected; and
prompt the user to switch a setting of the selectively set GNSS, which is the transmission source, from a setting for performing reception processing on the multi-band to a setting for performing reception processing on a single band that is a signal in one frequency band.
