Casters

A caster is the center of the NTRIP setup. Base stations publish correction streams to it, and rovers or field apps connect to it to receive those corrections.

The caster list shows the casters in the account. When counts are enabled, you can also see how many instances, mount points, and clients belong to each caster.

Creating a caster

To create a caster, enter a name. Use something your team will recognize later: a project, region, customer, or operating area.

A caster does not accept connections by itself. It needs at least one instance running on a server.

Caster page

When you open a caster, the left menu changes. Instead of the main account menu, you see sections for that caster:

• Instances shows where the caster is running and which ports it uses.
• Mount points are the base station connection points.
• Clients are credentials for rovers and apps.

These sections belong to the selected caster, not the whole account.

Instances

An instance is a running copy of the caster on a specific server. When you create one, you choose the server and ports:

• NTRIP port is used for NTRIP connections, often 2101;
• HTTP port is used for HTTP access and service requests, for example 8080.

The instance page shows status, configuration, events, and authorization attempts.

Useful actions include:

• updating the configuration after changes;
• installing or uninstalling the instance on the server;
• checking events when a caster will not start or behaves unexpectedly;
• checking authorizations when a base or rover cannot connect.

Mount points

A mount point is where a base station connects and where rovers get correction data. The form includes:

• a mount point name, unique within the caster;
• username and password for the source connection;
• NTRIP version: Any, v1, or v2;
• password encryption;
• an optional user or group that should see the mount point in the field app.

For NTRIP v1, the username may be hidden because the connection format is different. If you save an encrypted password, it cannot be shown again in plain text later.

From the mount point page you can update settings, delete the mount point, configure the source, and manage access.

Mount point source

The source describes where corrections come from. In most cases it is a base station or an external NTRIP source. Source settings let you update connection details or temporarily override the stream.

That is useful when:

• the base station address or port changes;
• a stream needs to move to another instance;
• the current source is down and you need a backup.

Clients

A client is a set of credentials for a rover, app, or other correction consumer. The form includes:

• owner;
• username and password;
• NTRIP version;
• expiration date;
• password encryption.

The username must be unique within the caster. Leave the expiration empty if the client should not expire automatically.

Clients make field access easier to manage. You can issue one login per rover, then disable or replace that login without touching the rest of the setup.

Renaming and deleting

A caster can be renamed or deleted. Before deleting one, check its instances, mount points, and clients. Deleting a caster affects the whole NTRIP setup behind it, so move or stop active connections first.
