Creating a Local Base Station with Your Used GNSS Receiver

If you’re working in areas without reliable NTRIP correction services or want more control over your GNSS operations, setting up a local base station is the way to go. Many used GNSS receivers — such as the Trimble R8, Topcon Hiper V, or Leica GS series — still support full RTK base capabilities.

🎯 Why Set Up a Local Base Station?

✔️ Independence from internet-based correction (NTRIP)
✔️ Reduced RTK latency & faster FIX times
✔️ Ideal for remote sites, agriculture, or construction zones
✔️ More reliable correction over short baselines (0–5 km)

🧰 What You’ll Need

📡 1x GNSS receiver with base station capability (Trimble, Topcon, Leica, Emlid, etc.)
🔌 Radio modem (UHF, LoRa, or built-in)
🔋 Power supply (battery or solar)
📍 Accurate known base position (or average position)
📱 Configuration software (Field Genius, SurvCE, Emlid Flow, etc.)

📐 Step-by-Step Setup Guide

Mount Your GNSS Base on a stable tripod or pole in a clear-sky area
Power On the receiver and connect via cable, Bluetooth, or Wi-Fi
Configure the Base Mode:
- Set operation to “Base Station”
- Enter known coordinates or use “Average FIX” if unknown
- Select output correction type: RTCM 3.2 or CMR+
Set Radio Output (optional):
- Configure UHF/LoRa modem settings (channel, power, baud rate)
- Ensure same settings are matched on the rover
Save and Start Broadcasting corrections
Test with Your Rover receiver by attempting RTK FIX connection

🛰️ Choosing the Right Base Position

To minimize drift and increase accuracy:

📍 Use a previously surveyed point if available
🧮 Alternatively, “Average FIX” for 10–20 minutes
📌 Record this position for future sessions

⚠️ Changing base position coordinates will cause shift in RTK rover measurements!

🛠️ Real-World Tips

🔋 Use solar power for long-term or all-day setups
🌦️ Protect gear with waterproof boxes or enclosures
🔄 Always double-check antenna height settings
🔍 Monitor base station health with an Android app or web UI (if supported)
