Space‑grade InSAR analytics for resilient infrastructure
High‑precision time‑series deformation from PS/SBAS/DS‑InSAR and TomoSAR, plus MAI & POT for along‑track and pixel‑offset displacements — at metropolitan scale.
Products
A complete, modular InSAR stack for DEM generation, differential & time‑series analysis, and 3D tomography.
DEM / DSM
Core interferometric processing with precise co‑registration, flattening, unwrapping and geocoding for high‑quality DEM/DSM.
Differential
Two/three‑pass deformation, with atmospheric correction (e.g., GACOS), residual‑baseline re‑estimation and trend removal.
Rate maps
Stacking of unwrapped interferograms to enhance SNR of persistent linear deformation signals.
Small Baseline
SVD‑based small‑baseline time‑series with spatiotemporal filtering for non‑linear deformation.
Persistent Scatterers
High‑density point clouds with mm/yr precision using robust modeling and adaptive networks.
Distributed Scatterers
Coherence‑aware homogeneous filtering and phase reconstruction for low‑coherence regions.
Tomography
L1‑based super‑resolution SAR tomography to separate layover targets in dense urban scenes.
Along‑track
Multiple Aperture Interferometry for azimuth displacement (near N–S) using fore/aft looks.
Pixel Offset
Amplitude cross‑correlation for large displacements and glacier/landslide tracking.
Solutions
City‑scale monitoring and risk intelligence for transportation, utilities and public safety.
Urban subsidence & asset health
Metro lines, high‑rises, reclamation areas and underground works; citywide risk screening with mm‑level accuracy.
Bridges & airports
Thermal expansion, runway settlement and structural stability for cross‑sea bridges and hub airports.
Route planning & mega‑projects
Support for complex mountain railways and long‑span infrastructure in harsh environments.
Geohazards
Wide‑area landslide and slope deformation surveillance for resilient regions.
Dams & energy
Identify uneven settlement and downstream slope deformation near hydropower assets.
