# Agriculture

RTKdata works with any agricultural guidance system that supports standard NTRIP connections. This page covers compatibility, setup tips, and common issues for precision agriculture.

***

## The Compatibility Rule

> **If your guidance display or receiver has an NTRIP menu where you can enter a server address, port, mountpoint, username, and password — it works with RTKdata.**

RTKdata delivers standard RTCM 3.x corrections via NTRIP. This is an open industry standard supported by virtually all modern precision agriculture equipment.

## Known-Compatible Agriculture Systems

### FieldBee (by eFarmer)

* **Compatibility:** Full
* **Models:** FieldBee RTK GNSS receiver, FieldBee auto-steer system
* **Setup:** Enter RTKdata credentials directly in the FieldBee app under NTRIP settings
* **Notes:** Popular aftermarket auto-steer solution. Works on John Deere, Case IH, New Holland, and most other tractors.

### FJ Dynamics (FJD)

* **Compatibility:** Full
* **Models:** AT-1, AT-2, AT-2 Plus auto-steer systems
* **Setup:** NTRIP settings in the FJD controller app
* **Notes:** Budget-friendly auto-steer. Supports RTKdata out of the box.

### Raven

* **Compatibility:** Full
* **Models:** Viper 4, Viper 4+, RS1, Hawkeye
* **Setup:** Go to correction source settings, select NTRIP, enter RTKdata server details
* **Notes:** Widely used in North American agriculture.

### Trimble Agriculture (NAV 900, GFX-750, GFX-1260)

* **Compatibility:** Full — but requires correct setup
* **Setup:** Select **"Internet RTK"** or **"Single Base RTCM"** as correction source — **NOT "VRS" or "Network RTK"**
* **Warning:** Trimble ag displays default to VRS mode. RTKdata is NOT a VRS network. See the [Trimble Receivers](https://github.com/Konstihh/rtkdata-docs/blob/main/integration-hub/agriculture/gnss-rovers-and-receivers/trimble-receivers.md) page for detailed instructions.

### Topcon Agriculture

* **Compatibility:** Full
* **Models:** X35, X25, Horizon displays
* **Setup:** Standard NTRIP input in correction settings

### Hemisphere / Outback

* **Compatibility:** Full
* **Models:** A320, A321, S-Drive, eDriveX
* **Setup:** Configure NTRIP in the correction source menu

### AgLeader

* **Compatibility:** Full
* **Models:** InCommand 800, InCommand 1200
* **Setup:** Configure in RTK correction source settings

### Müller Elektronik

* **Compatibility:** Full
* **Models:** TRACK-Leader, FIELD-Nav
* **Setup:** Standard NTRIP configuration

### CLAAS GPS Pilot

* **Compatibility:** Check with dealer
* **Notes:** Some CLAAS systems with built-in GPS Pilot may require CLAAS-specific correction services. Check with your CLAAS dealer whether the system accepts standard NTRIP input.

### John Deere StarFire

* **Compatibility:** Limited — StarFire receivers cannot connect to third-party NTRIP directly
* **Models:** SF1, SF3, SF6 receivers use a proprietary correction format
* **Workaround:** Use a third-party GNSS receiver with NTRIP capability (e.g., FJ Dynamics, FieldBee, or a standalone u-blox receiver) and connect it to the tractor's guidance system via serial or CAN bus
* **Note:** Aftermarket systems like FieldBee and FJD offer complete replacement guidance with full RTKdata support

### Agricultural Drones

* **DJI Agras T50/T40/T25** — Full compatibility. See [DJI Agras setup guide](https://github.com/Konstihh/rtkdata-docs/blob/main/integration-hub/agriculture/drones-and-uavs/dji-agras-t50-t40-t25.md)
* **XAG P100 / V40** — Full compatibility. Standard NTRIP input in controller.

## Setup Steps (General)

These steps apply to most ag guidance systems:

1. **Find the NTRIP / RTK settings** in your display's correction source menu
2. Enter the RTKdata server details:

| Setting           | Value                                                                                    |
| ----------------- | ---------------------------------------------------------------------------------------- |
| **Host / Server** | `rtk.rtkdata.com` (Global) or `eu.rtkdata.com` (Europe) or `aus.rtkdata.com` (Australia) |
| **Port**          | `2101`                                                                                   |
| **Mountpoint**    | `AUTO` (ALL CAPS)                                                                        |
| **Username**      | Your NTRIP username (starts with `rtk`)                                                  |
| **Password**      | Your NTRIP password                                                                      |

3. **Save and connect** — wait for RTK FIX (usually 30–90 seconds)
4. **Verify accuracy** — check the RTK status indicator on your display

## Internet in the Field

Agricultural equipment often operates in remote areas. Internet options:

| Method                  | Reliability | Notes                                                               |
| ----------------------- | ----------- | ------------------------------------------------------------------- |
| **Phone hotspot (4G)**  | Good        | Most common. Mount phone on cab roof for better signal.             |
| **Dedicated 4G router** | Very good   | With external antenna — best for consistent coverage                |
| **Starlink Mini**       | Excellent   | Works in remote areas with no cell coverage. Power via 12V adapter. |
| **Wi-Fi extender**      | Variable    | Only if near a building with Wi-Fi                                  |

**Data usage:** RTK corrections use approximately **5–10 kbit/s** — negligible even on metered connections. A full day of farming uses less than 50 MB.

## Common Issues

### "My auto-steer drifts after working for a while"

* Check if RTK dropped from FIX to FLOAT (usually an internet issue)
* Verify your phone/hotspot hasn't gone to sleep
* Some guidance systems revert to WAAS/SBAS silently when RTK drops — check the correction source indicator

### "Accuracy is worse than expected"

* Check distance to nearest base station on the [Coverage Map](https://rtkdata.com/coverage/)
* Ensure you're using mountpoint `AUTO` (not `AUTO_WGS84` unless you specifically need WGS84)
* Verify you're connected to the nearest regional server

### "RTK disconnects when I cross field boundaries"

* This may be a hotspot signal issue — as you drive away from the phone/router, signal weakens
* Mount the hotspot device on the tractor, not in a stationary location
* Consider a 4G router with external antenna mounted on the cab

## Subscription Tips for Farms

* **One subscription = one machine** connected at a time
* If you run **multiple machines simultaneously**, you need one subscription per machine
* **Annual plans** ($33.33/month) offer significant savings over monthly billing for seasonal use
* The **5-year plan** is the best value for long-term farm operations
