Abstract: A network measurement device includes a display control unit that displays location information stored in a location information table and a setting control unit that sets the location information selected from the displayed location information as positioning start location information of a moving destination, and has a configuration of, after setting the positioning start location information, executing positioning at the moving destination based on reception signal information from a GNSS and measuring a time synchronization error between reference time information acquired from the GNSS and reference time information under test used by an apparatus in a location of the moving destination by comparing the reference time information and the reference time information under test.

Abstract: A network measurement device includes a setting control unit that sets, for example, a single GNSS as a transmission source of a signal of a multi-band, a multi-band abnormality detection unit that detects a multi-band reception abnormality based on an existing GNSS antenna receiving a signal in the multi-band transmitted from the GNSS, which is the transmission source, and reception signal information obtained by reception processing in a state in which the network measurement device is connected to the apparatus of a moving destination, for example, a boundary clock, and the existing GNSS antenna is connected to an antenna input terminal, for example, and an alert notification control unit that notifies a user of an alert notification that a multi-band reception abnormality occurs when a multi-band reception abnormality is detected.
