LT-1 SAR Satellite Imagery

The LT-1 constellation is a pioneering force in remote sensing, distinguished as the world's first L-band SAR constellation designed specifically for surface deformation interferometry. With the ability to measure ground movement with millimeter-level accuracy, LT-1 provides critical insights for infrastructure stability, geological hazard assessment, and DEM generation in any weather condition.

Features and Benefits

  • Millimeter-Level Accuracy: Specifically designed for interferometry, LT-1 can detect surface deformation with millimeter-level precision, essential for high-stakes monitoring.
  • All-Weather Penetration: The L-band SAR sensor penetrates clouds, rain, and darkness, and has a greater ability to penetrate vegetation canopies than C-band or X-band SAR.
  • Global DEM Generation: Its unique "flying around" mode is ideal for creating 1:50,000 DEMs, especially in equatorial regions that are persistently covered by clouds.
  • Versatile Polarization: Support for single, dual, and full polarization provides richer data, allowing for more advanced analysis of surface characteristics and land cover.

Applications

Surface Deformation Monitoring: Its primary application, used to detect minute ground movements for monitoring dams, bridges, pipelines, and identifying geological hazards like landslides and subsidence.
Oil & Gas Infrastructure: Conduct pipeline inspections and monitor for deformation and potential leaks, particularly in areas where adverse weather obscures optical views.
Global DEM Creation: Provides foundational elevation data for mapping, hydrology, and analysis, especially in challenging, cloud-covered tropical regions.
Environmental Monitoring: Monitor land use changes, forestry activities, and deforestation in consistently cloudy areas where optical sensors are limited.
Disaster Management: Offer critical all-weather support for monitoring flood zones, landslide-prone areas, and volcanic activity before, during, and after an event.
Urban Development & Defense: Contribute to various applications requiring high-precision terrain and stability data, regardless of weather conditions.
