DAILY COHERENT GROUND TRACK REPEAT

CAPABILITY DEMONSTRATION

persistent monitoring at its finest
detailed change detection from SAR satellites on a daily basis

WORLD'S FIRST

ICEYE is the first to achieve Daily Coherent Ground Track Repeat capability which enables change detection every day, with a very high precision.

HIGHLY-ACCURATE

Detect detailed changes on the ground, such as vessel movement, construction, infrastructure integrity - daily, in all weather and darkness.

TRUE PERSISTENT MONITORING

Measure ground disturbance from space with a very high level of detail, such as car tracks on the gravel road and detailed terrain elevation changes.

DAILY COHERENT GROUND TRACK REPEAT - HOW DOES IT WORK?

  • Maintaining very precise satellite passes over a location makes it possible to acquire exactly similar SAR images 
  • This allows the extraction of detailed information about ground changes to a level unreachable to non-coherent imagery, further enabling automated persistent monitoring
  • With this capability, ICEYE enables persistent monitoring more repeatedly and consistently than it has ever been possible before

EXAMPLE EXPLOITATION TECHNIQUES

 

Amplitude Change Detection obtained over the Port of Rotterdam, Netherlands with ICEYE Daily Coherent GTR data.

AmPLITUDE CHANGE DETECTION

  • Simple and fast method
  • Clear and precise indication of small changes over time 
  • Difference between stacked images visualized in colors
  • On the right, blue is a "positive" change, red is a "negative" change

COHERENT CHANGE DETECTION

  • Advanced and most precise change detection method
  • Detecting changes between two images that are not visible to a human eye
  • On the right, comparison of two consecutive CCD analysis. What has changed between consecutive days is shown dark, what remains the same is shown bright
