Organization Profile

NextAV is an organization dedicated to advancing Earth observation and super-resolution technologies for remote sensing applications.

Mission

To advance the state of the art in satellite super-resolution and Earth observation analytics through open research, rigorous engineering, and responsible AI practices.

Core Activities

Domain	Description
Optical Super-Resolution	Sentinel-2 L2A reflectance super-resolution from 10 m to 1–2.5 m GSD using multi-temporal deep learning
SAR Super-Resolution	Cross-band Sentinel-1 C-band (10 m) → Capella X-band (sub-meter) using diffusion and flow matching models
Emission Intelligence	Airborne hyperspectral methane plume detection and carbon signature mapping using spectral absorption-aware transformers
Inference & Deployment	Production inference tooling for CPU/GPU and AWS Marketplace ECS deployment
Geospatial Analytics	Multi-sensor data fusion, preprocessing pipelines, and geospatial dataset construction
