PRODUCT SYSTEM

SCAN → WATCH → PROVE

Three connected service levels cover historical context, recurring measurement and stronger ground control.

01

SCAN

Locate and contextualise motion.

Historical and current radar archives support a first spatial assessment. We define observable areas, deformation patterns and priorities before a monitoring commitment is made.

Best for
Portfolio screening, corridor review, due diligence and a first technical question.

Outcomes

  • Archive and geometry assessment
  • Velocity and displacement layers
  • Areas for follow-up
  • Technical interpretation memo
Scope a SCAN
02

WATCH

Maintain a comparable time series.

Repeat processing follows selected locations, corridors or portfolios as new acquisitions arrive. Quality indicators and declared reference choices remain attached to every series.

Best for
Assets and areas that need recurring evidence, change review and controlled delivery.

Outcomes

  • Scheduled updates
  • Point and area time series
  • Quality and change review
  • Controlled web delivery
Scope a WATCH
03

PROVE

Strengthen the measurement design.

Corner reflectors, active radar targets, GNSS, levelling and other sensors can improve observability or add independent ground evidence where the decision requires it.

Best for
Critical locations, difficult radar response and decisions that need a stronger validation chain.

Outcomes

  • Radar-visibility and siting design
  • Passive or active target plan
  • GNSS or levelling integration
  • Joint technical interpretation
Scope a PROVE

CLIENT EXPLAINERS

Three concepts behind the service.

InSAR
InSAR compares radar phase across repeated satellite acquisitions. Persistent targets provide displacement time series in the sensor line of sight. The result supports screening, monitoring and investigation across wide areas.
PSI / PSInSAR
The method follows radar-stable ground targets across many acquisitions. Built surfaces and infrastructure can provide dense, comparable time series where coherence is sufficient.
Passive and active radar targets
A passive corner reflector returns the satellite signal through its geometry and needs no power. An active target receives and retransmits a controlled signal; it adds operational complexity and can provide a stronger configurable response. Site geometry, access, maintenance and the measurement objective guide the choice.

SERVICE SELECTION

Service selection starts with observability

Before processing begins, we determine what satellite data can reliably measure at the site. We assess archive depth, radar-target stability, acquisition frequency, orbit geometry and the expected movement direction—then define a defensible scope and precision. A single radar geometry captures only the component of motion along the satellite’s line of sight and relative to a chosen reference; it does not provide full 3D movement.
