Go to Account Details > User Profile and record the NTRIP username and NTRIP password. This will be used in the NTRIP profile.
Entering the NTRIP credentials for your drone or Emlid device will be very similar. We will show an example with Emlid. On the DJI app you will enter the credentials under the RTK settings and Select RTK Service Type Custom Network RTK.
For the Emlid Reach receivers the NTRIP credentials may be entered in Emlid Flow, MicroSurvey FieldGenius, Carlson, or another data collector. In this example we will look at Emlid Flow.
NTRIP corrections require internet access. Make sure your phone/tablet has cell service or is connected to a hotspot. Connect to the Reach receiver over bluetooth, set the Correction Input to NTRIP over Bluetooth. Add the FPRN credentials in a new NTRIP profile.

The profile name is arbitrary. If the address, port, or mount point changes for any reason, you will be notified by FPRN. Florida offers network mount points. The network uses multiple surrounding base stations to create a virtual base station on site. This is a way to reduce the effect of longer baselines, and requires less physical base stations throughout the state. Emlid receivers require a mount point in RTCM3 format. RTCM3_VRS is in RTCM3 format.
