• Set up Bluetooth communication with the GPS: General Survey -> Instruments -> GNSS functions -> Bluetooth
  • identify both the rover and the base GPS here.
• Set the Survey Style: Main Menu -> Settings -> Survey Styles
  • rtk int radio = internal radios on both gps
  • RTK = use an external radio for the base.

http://facility.unavco.org/project_support/polar/barrow/equip.html I have added a new base radio & configuration to the

Following existing points is called 'Stakeout'

So, maybe the TDL450 radio can't tie in to the barrow network, which seems to operate at 418 MHz (which makes sense since we need to receive data not transmit it): http://facility.unavco.org/project_support/polar/barrow/equip.html //In addition, the base station transmits real-time kinematic (RTK) broadcasts at 418 MHz (CMR+ format at 9600 baud). //

Handy document showing how to change the receive frequencies for the R8 so that it can receive Toolik and Barrow freqs: http://cody.inlandgps.com/pub/Trimble%20Stuff/Instructions%20by%20Inland%20GPS/Installing%20Receive%20Frequencies.pdf
