# Connect a receiver

## Connect a receiver to our NTRIP caster

To receive RTK Premium corrections, connect your receiver to our NTRIP caster using your account credentials. The steps below are generic and work with any NTRIP-capable receiver. The menu names differ from one brand to the next, but the settings you enter are the same everywhere.

If you have not connected over NTRIP before, [What is NTRIP](/learn/what-is-ntrip.md) explains the caster, mountpoint, and GGA heartbeat in plain terms.

### Before you start

* An NTRIP-capable GNSS receiver or controller.
* An internet connection for the receiver, whether through its own SIM, a paired phone or controller, or Wi-Fi or Ethernet for a fixed install.
* Your RTK Premium credentials, which arrive by email when your trial or subscription is set up. If you do not have them yet, start with the [free trial](https://www.premium-positioning.com/en/free-trial/).
* A clear view of the sky at the point you are measuring.

### Connection settings

Enter these in your receiver's NTRIP or correction-source settings:

* Caster address (host or server): rtkpremium.xyz
* Port: 2101
* Mountpoint: COMMON
* Username: your account username&#x20;
* Password: your account password&#x20;

Username and password are case sensitive. Use the exact values from your account email rather than the example shown here.

### Steps to connect

1. Open the correction settings. Look for a menu called NTRIP client, internet base, correction source, or data link, depending on your brand.
2. Create a new NTRIP connection and enter the caster address and port from above.
3. Enter your username and password.
4. Load the mountpoint list. Most receivers fetch the caster's list of mountpoints once the address, port, and credentials are in. Select COMMON. If your receiver does not fetch the list, type COMMON in the mountpoint field by hand.
5. Turn on position sending if your receiver asks. This sends your approximate position to the network as a GGA message, the heartbeat the network needs to tailor the correction to where you are. Leave it enabled.
6. Connect. The receiver requests the stream and starts receiving corrections. You should see the correction age begin to count in seconds.
7. Wait for a fixed solution. The receiver moves from an autonomous position to float, then to fixed. Once it reports RTK Fixed, you are positioning to 1 to 2 cm.

### Check it is working

* The solution status reads fixed, not float or autonomous.
* The correction age stays low, within a few seconds.
* If a known point is nearby, measure it and confirm the result matches its published coordinates.

### Choosing a different mountpoint

COMMON suits most receivers. Depending on your subscription and region, other mountpoints may be available, for example streams carrying different constellations or message sets. See [Mountpoint selection and the GGA heartbeat](https://claude.ai/chat/b419af49-7d48-49a1-832b-42d52fe66419#) for how to choose.

### If it will not connect

* No mountpoint list appears: re-check the address, the port, and your internet connection.
* Authentication failed: re-enter the username and password exactly, mind the capitals, and confirm your subscription is active.
* Connected but no fix: make sure position sending (GGA) is on, move to open sky, and give the receiver time to resolve the ambiguities.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.premium-positioning.com/set-up-and-connect/connect-a-receiver.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
