# Autel EVO II Pro RTK / Dragonfish

These steps connect an Autel EVO II Pro RTK / Dragonfish to the Premium Positioning correction network over NTRIP, using Autel Explorer / Autel SkyLink. They assume you already have your NTRIP credentials.

### Before you start

* Your NTRIP username and password, from your Premium Positioning welcome email or your account on the customer portal.
* Autel Explorer / Autel SkyLink.
* A working internet connection on the controller or phone.
* A clear view of the sky at the point you are measuring.

### Network settings

These are the same for every Premium Positioning customer. Only your username and password are unique to you.

* Server or host: rtkpremium.xyz
* Port: 2101
* Mountpoint: COMMON
* Protocol: NTRIP

### Steps

1. Power up and pair, and confirm the RTK module: Power on the aircraft and controller and wait for them to pair. Make sure the RTK module is fitted and recognised. RTK corrections are received by the aircraft but configured from the controller's app, so both must be linked first.
2. Give the controller a working internet connection: Network RTK over NTRIP needs the controller (running Autel Explorer / SkyLink) online to reach our caster. Connect it to a phone hotspot, site Wi-Fi or 4G before continuing. Without internet the NTRIP login fails even when every field is correct.
3. Open the RTK settings: Open the app and enter the camera/flight view. Tap the Settings (gear) icon, usually top-right, and find the RTK section ('RTK' or 'RTK Settings'). Wording/placement vary by app version and model - look for an 'RTK' tab or sub-menu.
4. Turn on the aircraft RTK feature: Enable RTK first - usually an 'RTK' or 'RTK Aircraft' toggle at the top of the RTK screen. This switches the aircraft into RTK positioning and reveals the correction-source options.
5. Choose the custom NTRIP / Network RTK source: The RTK source list typically offers Autel's own network/RTK service, a physical base station (D-RTK / mobile station), and a custom network option. Select the custom one - 'Custom Network RTK', 'Network RTK', 'NTRIP' or 'Custom NTRIP'. Do NOT pick Autel's own service or 'Base station'. Pick whichever lets you type in your own server address.
6. Enter the caster host (server): In the server/host field enter: rtkpremium.xyz - exactly, no http\:// and no trailing slash/spaces.
7. Enter the port: In the port field enter: 2101
8. Enter the mountpoint: In the mountpoint field enter: COMMON (capitals). Some versions show mountpoints as a drop-down populated after connecting - if it's a list, connect first then choose COMMON; if a text field, type COMMON.
9. Enter YOUR NTRIP username and password: In account/username and password, enter the personal NTRIP credentials from your welcome email - unique to your account; do not use anyone else's. If lost, contact Premium Positioning support first.
10. Connect / log in: Tap Connect, Apply or Login. A success/'Login successful' state should appear. If login fails, re-check the controller's internet, host/port/mountpoint, and that your username/password were typed correctly (watch for autocorrect or trailing spaces).
11. Confirm the format is RTCM3: Our caster sends RTCM3, which Autel aircraft need. If the app lets you choose a format, leave it on RTCM3. Autel drones won't reach FIX on CMR/CMRx mountpoints - stay on the RTCM3 COMMON mountpoint.
12. Wait for the RTK status to reach FIX: Watch the RTK status in the top status bar: SINGLE → FLOAT → FIX, typically within \~10 - 60 s of a successful login under open sky. FIX means full cm-level RTK and you're ready to fly. If it sticks on FLOAT, give it more time with clear sky; if it never leaves SINGLE, corrections aren't being delivered - recheck the steps above.

### If the fix will not hold

Menu names, gear-icon location and the RTK source labels differ between Autel Explorer and SkyLink and between app/firmware versions - treat the wording as a guide and pick the equivalent option. The controller must have its own internet connection for NTRIP.
