Satellites orbiting the Earth pass over the same area at regular intervals and photograph it. ESTRON uses these images from the free, public Sentinel-2 satellites to monitor how healthy your plants are.

How often do new images arrive?

Across Türkiye the same field is re-imaged roughly every 2–5 days. That is frequent enough to catch changes in your plants long before they become visible to the eye, and more than enough for irrigation decisions.

What does ESTRON do with these images?

With every new image, ESTRON measures how green and vigorous your plants are. If plants in an area are under stress or their water demand is rising, it sees this early and sets irrigation priorities accordingly.

  • Shows which area needs more water.
  • Catches drying and stress signs early.
  • Prevents unnecessary watering, saving water and energy.

What happens on cloudy days?

Satellites cannot see through clouds, so on overcast days an image may be delayed. In those cases ESTRON keeps the irrigation plan running using the most recent clear image together with weather data. When the sky clears, the latest image kicks in automatically.

In short: satellites review your field every few days and ESTRON interprets that information for you. Without you lifting a finger, your system directs water to where it is needed most.
