# Eos Arrow Gold / Arrow 100

Connect Eos Arrow Gold / Arrow 100 to RTK Premium corrections over NTRIP.

These steps connect an Eos Arrow Gold / Arrow 100 to the Premium Positioning correction network over NTRIP, using Eos Tools Pro (+ a GIS app). 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 in the XYZ Platform.
* No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=eos-arrow-gold-arrow-100) to get your credentials.
* Eos Tools Pro (+ a GIS app).
* A working internet connection on the controller or phone.
* No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=eos-arrow-gold-arrow-100#iot-sims) give it its own data connection.
* 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. Charge and power on the Arrow: Power on your Arrow Gold (or Arrow 100/200) with a clear view of the sky. Have your GIS app (e.g. ArcGIS Field Maps) and Eos Tools Pro installed on the same phone/tablet.
2. Pair the Arrow over Bluetooth: iOS: pair the Arrow in system Settings > Bluetooth before opening Eos Tools Pro. Android: connect from within Eos Tools Pro (Android also needs Developer Options > mock location set to Eos Tools Pro, with 'Replace Device Location' enabled). Wait for connected status.
3. Confirm a raw GNSS position: Open Eos Tools Pro > Status menu > Position tab. Confirm coordinates are populated (autonomous/GPS solution) before adding corrections.
4. Open the NTRIP correction settings: Tap the Differential menu and select the NTRIP tab. Wording varies slightly by version/platform - look for the NTRIP / corrections section.
5. Set the protocol: Set Protocol to NTRIP (standard HTTP). Only use HTTPS if your provider tells you to.
6. Enter the caster address and port: IP Address / Server: rtkpremium.xyz Port: 2101 - the same for every Premium Positioning customer.
7. Enter your NTRIP credentials: Tap the Credentials field and enter YOUR OWN NTRIP username and password exactly as in your welcome email (case-sensitive); do not use anyone else's. Tap Done.
8. Retrieve the source table: Tap the Mountpoint field so Eos Tools Pro queries the caster and loads the source table. If it won't load, double-check host, port and credentials and confirm internet; you can also open rtkpremium.xyz:2101 in a browser to verify the source table downloads.
9. Select the COMMON mountpoint: From the list select COMMON - correct for all Premium Positioning customers. Tap Done.
10. Start streaming corrections: Tap Start Streaming. The Arrow begins receiving corrections (the green Tx LED blinks). You can enable Auto-start streaming and Save as New Profile for next time.
11. Confirm a Fixed RTK solution: Return to Status > Position and watch Autonomous → Float → Fixed (Android shows Diff Status = RTK Fixed). When Fixed, HRMS drops to a few cm, Diff Age settles \~1 - 2 s, and a Diff Station ID appears.
12. Use it in your GIS app: With Eos Tools Pro streaming in the background, open ArcGIS Field Maps (or your GIS app) and confirm it uses the Arrow's high-accuracy location. Keep Eos Tools Pro running while collecting.

### Eos Tools Pro settings

* Turn on Send GGA: Enable send GGA so the network receives your approximate position.

### If the fix will not hold

Menu/field names (Differential / NTRIP / Mountpoint / Credentials / Start Streaming) differ slightly between iOS and Android and app versions; choose the closest match. A Fixed solution needs clear sky and internet. If it won't fix, recheck host/port/COMMON and credentials, then stop and restart streaming.
