What are common RTK troubleshooting issues?

In the field of high-precision positioning, Real-Time Kinematic (RTK) technology has been widely applied in surveying, precision agriculture, UAV mapping, and autonomous driving. Despite its centimeter-level accuracy, users often encounter various technical issues that affect both experience and operational efficiency.

Common Issues and Causes

1. Unable to achieve Fixed solution

• Symptom: The receiver remains in “Float” or “Autonomous” mode for a long time, preventing centimeter-level accuracy.

• Possible causes:

  • Incorrect base station configuration

  • Unstable radio links

  • Improper NTRIP service connection

2. Positioning errors despite Fixed status

• Symptom: Even when the receiver shows “Fixed,” coordinate data may still be inaccurate.

• Common causes:

  • Incorrect base station coordinates

  • Signal reflections (multipath effects)

  • Natural factors such as ionospheric or tropospheric delays

3. Signal loss or interruption

• Symptom: In urban canyons, dense forests, or near high-voltage lines, GNSS signals may be blocked, causing unstable RTK solutions.

4. Improper base station placement

• Symptom: Base stations set up in obstructed or complex environments can lead to unstable data transmission and unreliable results.

Expert Recommendations

Industry experts suggest the following to minimize RTK issues:

1. Regularly check receivers, antennas, and base station equipment

2. Ensure coordinate systems match project requirements

3. Operate in open, unobstructed environments whenever possible

4. Keep firmware updated and perform routine maintenance
