Competitive landscape
Multispectral imaging (Sentinel-2, Landsat: 10–13 broad bands) handles most commodity use cases at lower cost and higher cadence. Thermal IR imagers (LWIR) compete for emissions monitoring. SAR offers all-weather, day-night operation but no chemical specificity. Airborne hyperspectral (AVIRIS-NG, HySpex) gives higher SNR and flexibility but no persistent coverage. On the detector side, InGaAs FPAs (SWIR) and HgCdTe (LWIR) are the incumbent materials; emerging CMOS-integrated filter arrays threaten cost structure.
