GR-8018 UDR Not Showing as Enabled in NaviViewer After Standard GPS Test
Quote from GPSWebShop Official on May 27, 2026, 10:16 amCustomer's question:
I just completed a standard system test on the GPS unit, and everything appears to be working properly.
I have a question about the UDR function. In NaviViewer, while viewing the live data, I could not see UDR showing as enabled. I have not yet completed the standard movement/calibration routine mentioned in the manual.
Will UDR become enabled automatically once the unit starts moving, or is there another step that needs to be completed before sending the units out for use?

Please refer to the “Application” section in the GR-8018 flyer. The calibration should be done after the receiver is mounted in its final position, ideally in an open area such as a parking lot with good GNSS signal.
Once the alignment reaches Coarse/Fine, NaviViewer should show the DR indication, and UDR will begin working.
