Introduction

An RTK Base Station is the reference point for an RTK survey. It is installed on a known control point and continuously sends correction data to the RTK Rover. A correct setup ensures accurate positioning and reliable survey results throughout the project.

Equipment Required

Before starting, make sure you have the following equipment:

• RTK GNSS Receiver
• GNSS Antenna
• Heavy-Duty Tripod
• Tribrach
• Survey Controller
• Radio Antenna or NTRIP Internet Connection
• Battery or External Power Supply
• Measuring Tape
• Bubble Level

Step 1 – Select a Suitable Control Point

Choose a control point with known Northing, Easting, and Elevation. The location should have a clear view of the sky and be free from trees, buildings, power lines, or other objects that may block satellite signals.

---

Step 2 – Set Up the Tripod

Place the tripod directly over the control point and make sure it is stable. Adjust the legs until the tripod head is approximately level.

---

Step 3 – Install the RTK Receiver

Mount the RTK GNSS receiver securely on the tripod or tribrach. Ensure that all connections are tight and the receiver is perfectly centered over the control point.

---

Step 4 – Measure the Antenna Height

Measure the antenna height carefully and enter the correct value into the survey controller. Even a small error can affect the accuracy of the survey.

---

Step 5 – Configure the Base Station

Open the survey software and enter the known coordinates of the control point. Select the correct coordinate system, correction format, and communication method, such as UHF Radio or NTRIP.

---

Step 6 – Start Broadcasting Corrections

Start broadcasting RTK correction data. Check that the rover receives the corrections successfully before beginning the survey.

---

Step 7 – Verify Accuracy

Use the RTK Rover to check another known control point. If the measured coordinates match the known values within the expected accuracy, the Base Station is ready for survey work.

---

Common Mistakes to Avoid

Avoid setting up the Base Station near tall buildings, trees, metal structures, or power lines. Always measure the antenna height correctly and double-check the coordinate system before starting the survey.

---

Best Practices

Use a stable control point, fully charge the batteries, inspect all equipment before use, and monitor satellite availability throughout the survey to maintain consistent positioning accuracy.

Conclusion

A properly configured RTK Base Station is the foundation of an accurate RTK survey. Following the correct setup procedure helps surveyors achieve reliable centimeter-level positioning and ensures consistent survey data across the entire project.
