One Model. Any Resolution. Zero Retraining

</aside>

A flexible, multi-sensor architecture for Earth observation that unifies Sentinel-1 SAR, Sentinel-2 MSI, and Sentinel-3 OLCI & SLSTR data from 10 m - 1000 m GSD, built on a compute-adaptive vision transformer backbone.

This enables the use of smaller patch sizes at inference, providing a denser token sequence that is more effective for fine-tuning on limited data.
