If you're working in precision agriculture, you know that accuracy isn't just a luxury—it's a necessity. Whether you're planting seeds, managing crops, or harvesting, even a small error can cost time, money, and resources. That's where Real-Time Kinematic (RTK) technology comes in. RTK boosts your GNSS (Global Navigation Satellite System) accuracy from meter-level to centimeter-level, ensuring your machinery stays on track.

But setting up RTK signals can feel hard if you're new to the process. Don't worry—this simple guide breaks down everything you need to configure RTK for your FJD AT2 system. By the end, you'll be ready to connect your AT2 system in just 5 minutes.


What Is RTK?

RTK is a satellite navigation technique that uses real-time corrections to achieve ultra-precise positioning. Think of it as giving your tractor or harvester a more precise positioning direction that tells exactly where it needs to go, down to the centimeter. There are two main types of RTK setups:
  • Network RTK (NTRIP required): Uses an internet connection to pull correction data from a nearby reference station.
  • Radio RTK: Relies on a mobile base station (placed in your field) that broadcasts corrections via radio signals.
Both methods work with the FJD AT2 system, and we'll walk through how to set up each one.

The Pre-Setup Checklist

Before diving into configurations, make sure you've checked these steps:
Step 1: Place the antenna properly
  • Ensure the GNSS receiver antenna is securely connected to your AT2 system and the receiver is replaced in an open area, usually on the roof of the tractor.
  • Check the satellite number on your display terminal—24 or more satellites is ideal for strong signal reception.
Step 2: Confirm network or radio readiness
  • For network RTK (NTRIP): Confirm your device has a stable internet connection via SIM card or mobile hotspot.
  • For radio RTK (Mobile base station): Set up the base station in an open area, and connect the radio antenna between the base station and your AT2 navigation system.
Step 3: Check data compatibility
  • Verify that your RTK signal source (NTRIP or radio) is compatible with the FJD AT2 system.
Step 4: Keep your tractor within the working range
  • NTRIP & UHF base stations: Work up to 15 km from the signal source.
  • Standard mobile base stations: Operate within 3–5 km.


 

Option 1: Connecting to Network RTK (NTRIP)

If you want to use network RTK, you need to purchase an NTRIP account and follow these steps:
Step 1: Connect to the Internet
  • Use a SIM card or mobile hotspot to ensure your device is online.
  • On your FJD AT2 display, access the Correction Signal Source menu, and select Network RTK -> Ntrip.
Step 2: Enter NTRIP credentials
  • Host: Input the server address provided by your NTRIP service.
  • Mountpoint: Enter the specific mountpoint name.
  • Node: Select or manually input the nearest node.
Step 3: Log in
  • Enter your username and password (provided by your RTK service provider).
  • Wait for the system to show a green "Logged in" and click to log in.
Step 4: Check the RTK signal
  • Return to the homepage and look for the RTK signal bar in the top-right corner.
  • Wait 1–2 minutes. A full signal bar means you're connected with RTK and ready to navigate.

Option 2: Connecting to Radio RTK (Base Station)

If you're using a mobile base station, here's how to pair it with your AT2 system:
Step 1: Set up the base station
  • Place the base station in an open area, and connect the radio antenna to both the base station and your AT2 system.
  • On your FJD AT2 display, access the Correction Signal Source menu, and select Mobile Base Station RTK.
Step 2: Choose a pairing method
  • Option 1: Pair via Code (for T2 base station): Enter the pairing code found on the base station's black sticker (e.g., BSXXXXXX).
  • Option 2: Pair via Frequency (for T2 high-power station): Input the exact sending frequency set on your Harxon radio (e.g., 432.250 MHz).
  • Option 3: Pair via Channel/Universal Pairing: Select the channel/frequency, protocol, and baud rate matching your base station.
Step 2: Check the RTK signal
  • Return to the homepage and look for the RTK signal bar in the top-right corner.
  • Wait 1–2 minutes. A full signal bar means you’re connected with RTK and ready to navigate.

What If RTK Isn't Available?

If you're outside RTK coverage (e.g., remote areas with no internet or base stations), you can use these backup options temporarily:
  • SBAS (Satellite-Based Augmentation System): Provides free corrections with about 1-meter accuracy.
  • PPP (Precise Point Positioning): Offers 10–20 cm accuracy but requires longer initialization.
Note: Check if these services are available in your region before relying on them.


Conclusion

Configuring RTK for your FJD AT2 system doesn't have to be complicated. Whether you choose network RTK or radio RTK, following the steps above will ensure you're up and running quickly. Remember: precision starts with preparation. Double-check your setup, stay within the allowed range, and you'll use the AT2 with precise positioning accuracy from RTK.
