What Happens When your Correction Source Drops?

Article #17146

RTK networks that enhance GNSS accuracy are available worldwide. They may be free or paid, privately owned, or run by a government. To locate a network near you, please consult our database: Find an RTK Network. Juniper RTK is a Network RTK correction service offered by Juniper Systems that works well with Juniper Systems RTK-capable GNSS receivers. You can purchase Juniper RTK through a certified Juniper partner, online through the Juniper RTK web page, or as an add-on to your Uinta subscription.


The ability of your GNSS receiver to get and maintain RTK Fix can be affected by

  • Spotty or limited internet connectivity

  • Obstructions that block satellite visibility, such as buildings, trees, or fences

  • Working outside of the RTK service coverage area

  • Increased ionospheric activity (such as during solar storms)

  • Base station maintenance or local service outage

  • Selecting the wrong mount point (if not using Juniper RTK)


If your GNSS receiver cannot achieve an RTK Fix, it automatically applies the best available correction source for your environment and your device capabilities.
