Common RTK Setup Mistakes and How to Avoid Them

Even experienced professionals can make critical mistakes when setting up RTK systems. Learn from common pitfalls to ensure optimal performance and avoid costly errors in the field.

The Top 5 RTK Setup Mistakes

1. Poor Antenna Placement

The Problem: One of the most common mistakes is positioning the antenna too close to reflective surfaces, under tree canopy, or in areas with limited sky view. This significantly degrades signal quality and can prevent proper RTK initialization.

How to Fix It:

• Maintain minimum 15° elevation mask above horizon
• Keep antenna at least 2 meters from reflective surfaces
• Ensure clear view of sky in all directions
• Use a ground plane for handheld units to reduce multipath

2. Incorrect Communication Settings

The Problem: Mismatched communication parameters between receiver and correction source, or using wrong correction formats, can prevent RTK corrections from being received properly.

How to Fix It:

• Verify correction format (RTCM 3.x is recommended)
• Match baud rates and communication protocols exactly
• Test communication before heading to the field
• Keep backup communication methods ready

3. Ignoring Base Station Quality

The Problem: Using poorly positioned base stations or ignoring base station health indicators can result in unreliable corrections and reduced accuracy.

How to Fix It:

• Monitor base station signal quality indicators regularly
• Verify base station coordinates are accurate
• Check age of corrections (should be less than 10 seconds)
• Use multiple base stations when available for redundancy

4. Insufficient Initialization Time

The Problem: Starting measurements before RTK initialization is complete or ignoring fix quality indicators leads to inaccurate positioning data.

How to Fix It:

• Wait for “RTK Fixed” status before taking measurements
• Allow 2-5 minutes for proper initialization
• Monitor position quality indicators continuously
• Re-initialize if fix is lost during work

5. Wrong Coordinate System Setup

The Problem: Using incorrect datum, projection, or coordinate system parameters can result in systematic errors that affect all measurements.

How to Fix It:

• Verify project coordinate system requirements before setup
• Use correct datum and projection parameters
• Test setup with known control points
• Document all coordinate system settings for future reference

Equipment and Maintenance Issues

Battery Management Problems

Poor battery management is a frequent cause of field failures. Common issues include not charging batteries fully before use, ignoring low battery warnings, using old or degraded batteries, and having no backup power plan.

Best practices: Always carry spare batteries, monitor battery levels regularly throughout the day, use manufacturer-recommended batteries, and replace batteries that no longer hold adequate charge.

Firmware and Software Issues

Using outdated firmware versions, incompatible software configurations, skipping calibration procedures, and ignoring software updates can lead to performance problems and compatibility issues.

Best practices: Keep firmware updated to the latest stable versions, perform regular equipment calibration according to manufacturer specifications, and test equipment after any updates before field use.

Field Procedure Mistakes

Setup Errors

Critical setup mistakes include incorrect antenna height measurement, not leveling the antenna properly, measuring to the wrong reference point, and using inconsistent setup procedures between measurements.

Quality Control Oversights

Skipping redundant measurements, not checking against known control points, ignoring quality indicators, and insufficient documentation can compromise the reliability of survey results.

Essential Quality Assurance Checklist:

Prevention Strategies

Training and Education

Regular equipment training sessions, staying updated on industry best practices, learning from experienced operators, and attending manufacturer workshops are essential for preventing common mistakes.

Standard Operating Procedures

Develop written procedures for equipment setup, create comprehensive setup checklists, implement quality control steps at each phase of work, and document lessons learned from past projects.

Regular Maintenance

Schedule regular equipment calibration, keep firmware updated to latest versions, maintain backup equipment in good working condition, and thoroughly test equipment before critical projects.

Emergency Troubleshooting

When Things Go Wrong in the Field:

1

Stop work immediately if RTK fix is lost - don't continue with degraded accuracy

2

Check communication links and satellite visibility indicators

3

Re-initialize the system and verify accuracy with known control points

4

Contact technical support if problems persist - don't guess at solutions
