Summary
Satellite imagery is not current. The latest analysis is from an earlier date.
Why this matters
Activity at military sites — vehicle movement, construction, equipment staging — can indicate preparation, rotation, or capability changes.

How sure we are
Last data: 2026-05-21 15:26 UTC
Basis: Sentinel-2 optical + Sentinel-1 SAR (revisit ~5 days)
Limitation: Cloud cover can block optical imagery. SAR provides backup but lower interpretability.
How we know
We analyze Sentinel-2 optical imagery (10m resolution) and Sentinel-1 SAR radar of monitored military sites. Changes are detected by comparing current imagery against seasonal baselines.
