NTRIP

NTRIP is a feature in IGC that allows users to feed RTCM correction data from a CORS network to their aircraft by connecting to an NTRIP casting service.

Setting up IGC NTRIP

Before you begin:

• Ensure the GCS has access to a stable internet connection. This can be achieved by connecting the controller via WIFI, cellular, or to a cellular-enabled smartphone via a hotspot.

• Ensure proper login credentials are obtained for the NTRIP caster of your choice. If you don’t have that information yet, you can still follow this guide with the example credentials provided.

  • Identify which corrections network you intend to use and register for an account (can take between 1 day and 1 week). WE RECOMMEND NOT ATTEMPTING THIS PROCESS IN THE FIELD.

Disclaimer: For the exclusive purposes of this guide, rtk2go.com, a public NTRIP casting service, is used to demonstrate connecting to a CORS network via the NTRIP widget in IGC. rtk2go.com is not affiliated with or endorsed by IFT, and its availability and performance with IFT products are not guaranteed.

Power on the Controller and verify it is connected to the internet.
Tap on the NTRIP widget on the upper right corner of the screen to display the NTRIP pop-up menu. Select Edit.
Enter the required credentials to connect to your NTRIP casting service. For this example, the following credentials were entered:
After the credentials are entered, tap the search icon to bring up a list of available mount points. Tap Vehicle Proximity (km) to sort the available mount points by their distance to the aircraft (NOTE: the drone must be powered on for this function to work. Otherwise the proximity will be displayed as Unknown, as shown below). Select the closest available mount point (top of the list). A closer mount point will provide more accurate corrections. NOTE: If the search feature is not working, confirm the credentials are entered in properly, and confirm that the controller has a stable internet connection. Alternatively, the desired mount point can be manually entered without the use of the search feature.
Tap Connect to connect to the NTRIP server. A green status message should appear, and the NTRIP widget should turn green. If this does not occur, confirm the login credentials (username and password) have been entered correctly, and confirm the controller is still connected to the internet.

Symbol Color	Status
Red	NTRIP server is not connected to IGC
Yellow	NTRIP server is connecting/reconnecting to IGC. This can happen after connecting if the controller’s internet connection is not stable.
Green	NTRIP server is connected to IGC

NTRIP Menu

Number	Feature	Function
1	NTRIP Status	Displays the current connection status between IGC and the NTRIP Server
2	Address	Address of the specific NTRIP Casting Service being used.
3	Port	Port used to connect to the NTRIP Server. Its value is 2101 by default. The specific port needed for connection will be specified by the NTRIP Casting Service. If no info is provided, use the default.
4	Mount Point	The specific ground station that is being used for corrections. This could be a physical station (CORS) or a virtual one (VRS).
5	Preset	Drop down menu used to select different presets. The user can create presets to save credentials for different NTRIP casting services, or for different mount points.
6	Edit	Opens the Edit NTRIP Settings menu used to configure the NTRIP connection.
7	Connect	Connects IGC to the NTRIP server.

Edit NTRIP Settings Menu

Number	Feature	Function
1	Close	Closes the Edit NTRIP Settings menu.
2	Add Preset	Creates a new blank preset.

10	Mount Point	The specific ground station that is being used for corrections. This could be a physical station (CORS) or a virtual one (VRS).
11	Username or Email	Login credential required by most NTRIP casting services. Obtain this information from the service being used.
12	Password	Login credential required by most NTRIP casting services. Obtain this information from the service being used.
13	Data Forward Preset	Opens a drop down to select an auxiliary device to forward NTRIP to. This is done independently of the aircraft. (Example: Sentera RTK-PPK Module)
14	Data Forward IP	IP address of the auxiliary device that NTRIP is being forwarded to.
15	Data Forward Port	Port of the auxiliary device that NTRIP is being forwarded to.
16	Connect on Start	Checking this box will automatically connect IGC to the preset NTRIP server when the app is launched.
17	Connect	Connects IGC to the NTRIP server.

Float vs Fix

While using RTK (either NTRIP over an internet connection or the Sentera Survey RTK/PPK unit), the GPS status in IGC will display either "RTK Float" or "RTK Fix", which corresponds to accuracy of RTK positioning (Fix is more accurate than Float). While using NTRIP without the Sentera Survey RTK/PPK unit, expect to see "3D RTK GPS Float" when selecting the satellite icon in IGC. For more information on the Survey RTK/PPK unit, see the Survey RTK/PPK page.
