We see roads breaking
from 600 kilometers above.
ASTRA uses satellite radar and AI to detect road damage across Thailand's entire highway network — before accidents happen.
50 people die on Thai roads.
Every single day.
Thailand has the deadliest roads in Southeast Asia. The WHO ranks it among the top 16 countries globally for road fatalities — 25.4 deaths per 100,000 people, every year. Poor road conditions are a major contributing factor, especially during monsoon season when surface damage becomes invisible until it is too late.
Thousands of accidents every year are linked to potholes and road surface failures. Most happen during or right after heavy rains, when roads collapse from below without warning.
lost every year to road crashes.
That's 6% of Thailand's entire GDP.

In 2025, a 30-meter crater opened on a Bangkok road and swallowed cars whole. 3,500 hospital patients had to be evacuated. Repairs will take over a year.

This is how Thailand inspects
72,000 km of highway.
5 Hawkeye trucks. 72,000 km of highway. A full survey cycle takes 2–5 years.

The Old Way
ASTRA
What if you could see every road,
every 6 days, from space?
ASTRA combines three satellite sources: Sentinel-1 SAR radar that sees through clouds and darkness, Sentinel-2 optical imagery for surface analysis, and Thailand's own THEOS-2 satellite at 0.5m resolution for spot checks. No trucks. No road closures. No waiting for clear skies.
Research shows 87% of road failures display subsurface deformation signals 12+ months before visible damage appears. ASTRA's InSAR technology detects these millimeter-level shifts — giving highway departments a year-long window to act before roads collapse.
Every road checked twice a month
Sees details the size of a car
Scans a strip wider than Thailand
Fresh data within a day
Three steps. Every road in Thailand.
Capture
Sentinel-1 SAR radar and Sentinel-2 optical satellites scan Thailand's entire 72,000 km highway network every 6 days — through clouds, rain, and darkness. All data is free and open from the European Space Agency.
Analyze
InSAR processing detects millimeter-level subsidence by comparing radar phase differences between orbits. Deep learning models trained on SpaceNet and DeepGlobe datasets analyze optical imagery for cracks, rutting, and surface degradation.
Prevent
Highway departments get a prioritized dashboard ranking road segments by severity. Targeted repair crews go straight to problem areas — no more blind patrols. THEOS-2 provides 0.5m imagery for critical spot checks.
The numbers behind the opportunity.
Thailand spends 13.9% of GDP on logistics. The US spends 9.1%. Bad roads are a big part of the gap.

Thailand spends over 2 billion baht per year on highway maintenance. Just a 5% efficiency gain from better targeting saves over 100 million baht annually — a 40:1 return on ASTRA's 9.2 million baht yearly operating cost. Italy, India, the Netherlands, and the UK already use satellite road monitoring. Thailand has everything it needs — GISTDA, THEOS-2, DOH digital records — it just needs the system to connect them.

Who we are
"We started ASTRA because we drove on Thai roads every day and kept asking: why does nobody know this road is about to fail until someone gets hurt?"
