Using RTK navigation in construction

RTK Navigation in Construction: The Future is Now

Have you ever wondered how modern skyscrapers grow with perfect precision? Or how massive excavators dig trenches without the slightest deviation from the plan? The answer lies in RTK navigation – a technology that is revolutionising the construction industry.

What is RTK Navigation?

RTK (Real-Time Kinematic) is a high-precision satellite positioning technology that can determine object locations with centimetre-level accuracy. Unlike conventional GPS, which can be off by several metres, RTK provides virtually jeweller's precision in real-time.

Practical Applications in Construction

1. Earthworks

• Excavators with RTK systems can dig trenches with 2-3 cm precision
• Operators see a 3D model of the site right in the cabin
• 80% reduction in errors and reworks

2. Site Planning

• Automatic ground levelling by bulldozers
• Creation of complex landscape forms
• Up to 40% fuel savings through route optimisation

3. Road Construction

• Precise adherence to design gradients
• Optimal asphalt laying
• 15-20% reduction in material consumption

Real Implementation Examples

On a residential complex construction in Kyiv, the use of RTK navigation allowed:

• 30% reduction in earthworks duration
• 25% decrease in fuel costs
• Increased work accuracy to 99%

During motorway construction, RTK systems provided:

• Perfect adherence to design gradients
• Material savings of 1.2 million UAH
• 45-day reduction in construction time

Advantages of RTK Navigation

1. Economic

• Reduced fuel and material costs
• Shortened construction timelines
• Minimised errors and reworks

2. Technical

• High work precision
• Ability to work at night and in poor visibility
• Automation of routine operations

3. Organisational

• Improved work planning
• Simplified quality control
• Enhanced construction site safety

Future of the Technology

Experts predict that by 2025, over 70% of large construction companies will be using RTK navigation. The technology is developing towards:

• Integration with BIM modelling
• Creation of fully autonomous machinery
• Expansion of remote control capabilities

Conclusion

RTK navigation isn't just a trendy buzzword; it's a genuine tool for improving construction efficiency. The technology enables resource savings, enhanced work quality, and improved site safety. Implementing RTK systems is an investment in the future of the construction industry.
