Synspective StriX SAR Data and Land Displacement Monitoring

Synspective is a Japanese space company whose shares are included in the TOPIX index. It builds and operates small 100 kg-class synthetic aperture radar (SAR) satellites called StriX, which observe the ground regardless of time of day, cloud or weather, and provides SAR data and remote monitoring services to government agencies and companies worldwide. Its first satellite launched in 2020, and it aims for a 30-satellite constellation for near real-time observation.

Besides selling StriX and ALOS-4 data through a data platform, Synspective offers cloud-based analytics solutions. Land Displacement Monitoring uses interferometric SAR (InSAR) to detect millimetre-level ground subsidence and deformation over wide areas, supporting periodic checks of roads, tunnels, railways, ports, airports, dikes, dams and energy facilities. Other solutions cover flood and disaster damage assessment, offshore wind and wave data, forest inventory management and object detection.

• StriX satellites: 100 kg-class SAR satellites with all-weather, day-and-night observation.
• SAR data platform: access to StriX and ALOS-4 data products.
• Land Displacement Monitoring: InSAR analysis of subsidence, uplift and landslides at millimetre level.
• Flood and Disaster Damage Assessment: rapid mapping of affected areas after events.
• Offshore Wind and Wave: SAR-derived data for offshore wind planning.
• Forest Inventory and Object Detection: forest management and classification of objects such as vessels.

• Expressway, metro and airport project owners monitoring settlement along alignments during and after construction.
• Provincial authorities in the Mekong Delta mapping land subsidence and riverbank deformation.
• Offshore wind developers and insurers using wind, wave and flood damage data for planning and claims.

• Radar imaging works at night and through cloud, which matters in tropical monsoon regions.
• Millimetre-level displacement detection gives early warning of subsidence and structural risk.
• Wide-area monitoring lowers cost and survey lead time compared with field levelling surveys, according to the vendor.
• Supports more frequent maintenance monitoring of remote or hard-to-access assets, including during disasters.

Small SAR constellations are making frequent all-weather radar monitoring affordable for infrastructure owners and disaster agencies. Vietnam faces land subsidence in the Mekong Delta and large cities, riverbank and coastal erosion, and is building expressways, airports and offshore wind projects, all of which benefit from regular, wide-area deformation and flood monitoring.
