RTK Configuration

This feature requires a Pro license

Use the Global Mapper built in NTRIP client to connect to a correction source within Global Mapper Mobile®. Using the Global Mapper Mobile® NTRIP client with a supported external device, all RTK correction information will be displayed in the Location Information for the connected GPS unit. The Satellite page and NMEA stream will reflect this information as well. This functionality will require internet or a cellular data connection when using a hosted NTRIP caster.

Note: Global Mapper Mobile® on iOS has been tested with the RTK enabled GPS devices from the following vendors: Bad Elf, Juniper and EOS (requires EOS Tools Pro app). Please contact mobilehelp@bluemarblegeo.com with any questions.
