GHGSat combines satellite and aircraft methane observations with SPECTRA analytics and API delivery. Satellite sensing uses short-wave infrared spectroscopy at approximately 25 m sampling, with emission estimates dependent on wind and atmospheric inversion. Its satellite threshold claim is 100 kg/h; aircraft figures near 3.5–3.6 kg/h at stated test conditions describe a different instrument. A Stanford-led controlled-release study independently quantified a 0.20 t/h release within 13% for one GHGSat observation. That result is site- and test-specific, not a universal accuracy guarantee.
Technical detail
Core features
Distinct satellite and aircraft methane measurement services
SPECTRA visualization and API data delivery
Published delivery windows of 24 hours after overpass and 48 hours after aircraft flight
Wind-dependent emission-rate inference with independent controlled-release evidence
Earth observation
Imaging spectrometer
Methane detection
Remote sensing
Emissions analytics
Use & integration
Recorded applications
Industrial emissions detection and verification
Remote infrastructure monitoring
Environmental compliance and response
Wide-area screening followed by targeted observation
These describe the reviewed application scope, not confirmed deployments, released requirements or procurement eligibility.
Evidence of maturity
Operational emissions-data services with independent satellite controlled-release evidence and supplier-described aircraft validation. Cloud cover, scheduling, wind and scene conditions limit acquisition and interpretation.
Commercial availability
Commercial satellite, airborne and analytics services are offered. Specify measurement layer, detection probability, wind/scene conditions, tasking and delivery window; revisit opportunity is not guaranteed usable daily coverage.
Integration and verification
Readiness
A technology readiness level is not established by the reviewed public sources.
The publicly described Satellite-based remote sensing and analytics offering may be relevant to monitoring or remote-operation use cases; this is a derived mapping for reviewer assessment.
This is a reviewed public-source assessment. It is not procurement eligibility, endorsement, customer interest, or classified demand.
