About
In order to properly use the RTK payload, it must receive correction data. Below are the two methods used to get this data to the D4K.
Using a Base Station
The base station approach is the simpler of the two, but requires more hardware out in the field.

About
This section will describe how to use the Sentera RTK Base Station (Gen 2) with the Double 4K RTK payload for PHX.
For use with a 3rd party base station please contact support@sentera.com.
Equipment
Sentera RTK Base Station
PHX CommsBox
Ethernet Cable
How To Use
The base station must be powered on and connected to the comms box CommsBox via ethernet.
The base station’s webpage can be visited at 192.168.143.31, to switch between survey-in and known position.
Once the base station has surveyed-in or position has been entered, it will start sending corrections data through the comms box.

Using NTRIP
NTRIP is a slightly more complicated solution, but requires less hardware.
Requirements:
Laptop with an internet connection.
An active account with the correction data from whatever state you are trying to fly out of (i.e. MNCORS for minnesota).
Ethernet cable for connecting to the comms box (laptop will be using wifi).
Setup
In order to use this corrections method, the NTRIP client is needed. It can be downloaded from the Sentera support pages (link to the right). The file must be extracted (unzipped) before use.
In the downloaded folder, run 'strscr.exe'. This should open the app.
Once open, select NTRIP Client under Type, and hit the Opt button, as shown. This will bring up an options panel, where the caster host and port should be entered, as shown.
Within the caster host, you need to find a proper mount point. Select the ‘Ntrip…' button to bring up a list. Select a mount point using RTCMv3, and copy it’s name. Paste it’s name into the mount point box. Enter your User-ID and Password, and hit OK.
Setup the UDP link as shown by clicking on the ‘Opt’ Button for the Output. Enter the broadcast options shown and hit OK.
Usage
Before NTRIP can be used, it needs an approximate location to work off of. To enter this, select the options button. From there, enter approximate coordinates (in decimal and meters) to the appropriate boxes and hit OK.
At this time, the link can be started, assuming the comms box is connected via ethernet. To do so, hit ‘Start’ on the client. You should see bytes start to count up, as well as a green box by Input. Allow a short amount of time for this to affect the PHX payload. Watch Fly PHX to check the type of GPS fix, or watch the lights on the RTK payload (see D4K RTK - Anatomy for light codes)
