Introduction
What is a heating system?
Why is it important?
What's the current state?
Heating system pipeline
Primary pipeline
Secondary pipeline

Ways of installation
Ground penetrating radar - What is that?
Modes
Distance
Time
Point

Case study
What is the goal?
How to achieve it?
Aibot X6
Payload 2kg
Speed 50km/h
Climb rate 8m/s
Flight time ~30 min
PI 400 LW
382x288 pixels
Spectral range 7.5 - 13 micrometers
Thermal range -20 - 100C, 0 - 250C, 120 - 900C
Accuracy 2%
What's the idea?
The results
Dark strap - a parked car
Temperature difference ~4C
Missing pipe 2x50
Pipe route does not match
Temperature difference ~9C, suggesting leakage
Area in the focus seems to be slightly hotter
Standard dimensions of the channel
• Concrete channel: 140x105cm, pipes 2 x 250mm
• Concrete channel: 90x75cm, pipes 2 x 80mm
• Concrete channel: 75x60cm, pipes 2 x 65mm

Location 1
Estimated width of the cover ~140cm points to two pipes of 250mm in diameter
Cover width allows us to estimate all other parameters
Location 2
Estimated width of the cover ~90cm, points to two pipes of 80mm in diameter
Location 3
Cover width of ~140cm, set of pipes 2x250mm
Location 4
Width of ~75cm, set of pipes 2x65mm
Location 5
Cover width of ~140cm, set of pipes 2x250mm
Display of a pipeline set directly into the ground
Scanned with a 900MHz antenna
2x250mm, at ~0.9m depth
*All the locations were scanned with a 200MHz antenna
Conclusion
Main advantages
Speed
Easy comparison
Integration with a GNSS
Export of the data into GIS formats
3D models
Thank you for your attention,
you rock!
