PMP Synchronization Solutions User Guide Configuring a CMM4PMP-0297 007v001 (January, 2017) 3-46Attribute MeaningDate from GPS This field displays the month, day, and year that the CMM4 receives.Time from GPS This field displays the hour, minute, and second that the CMM4 receives.AntennaConnectionThis field indicates the health of the connection between the CMM4 and theGPS antenna. For example, a value of “BAD – Under Current” indicates thatthere is a lack of signaling due to a bad cable or GPS module.Tracking Mode If the CMM4 receives the signals from a GPS antenna, then this fieldindicates the degree to which the CMM4 is accurately computing positioninformation, given the satellites that it is tracking. For example2D Fix indicates that the CMM4 has a lock on information that is sufficient tocompute position.Bad Geometry indicates that it does not.Latitude If the CMM4 receives the signal from a GPS antenna, then this field displaysthe latitude of the site.Longitude If the CMM4 receives the signal from a GPS antenna, then this field displaysthe longitude of the site.Height If the CMM4 receives the signal from a GPS antenna, then this field displaysthe elevation (above sea level) of the GPS antenna.Invalid MessageCountNumber of messages sent from the GPS receiver for which there is nomatch.Restart Count It is incremented when the CMM4 is having difficulty communicating withthe GPS moduleReinit Count The number of times the GPS device has been completely reinitializedViewing the System LogAn example of the CMM4 System Log tab is displayed in Figure 26.Figure 47 System Log tab of the CMMThe System Log tab provides a record of events that have been significant to this CMM4.
