## How It Works

Machine control systems use RTK corrections to position the bucket, blade, or drum in real time — typically achieving **10–20 mm accuracy**. The GNSS receiver on the machine connects to RTKdata.com via NTRIP (using a cellular modem), receives RTCM3 corrections, and feeds the corrected position to the machine control display.

## Quick Setup

All systems use the same RTKdata.com NTRIP settings:

```
Host:       eu.rtkdata.com / rtk.rtkdata.com / aus.rtkdata.com
Port:       2101
Mountpoint: AUTO
Username:   (from RTKdata dashboard)
Password:   (from RTKdata dashboard)
GGA:        ON (required)
```

Select your system above for step-by-step instructions.
