Satellite Coverage
Summary
Satellite analysis fresh (latest 2026-04-09 15:06:49 UTC).
Why this matters
Activity at military sites — vehicle movement, construction, equipment staging — can indicate preparation, rotation, or capability changes.
What we saw
The Kapustin Yar range shows a moderate change in VV polarization and a low VH/VV ratio, suggesting minimal activity. No aircraft are visible and the runway appears clear.
The SAR data indicates normal activity at Millerovo airbase. The runway appears clear and there are few vehicles visible.
The SAR radar data indicates normal activity at Morozovsk airbase. There are no visible aircraft or vehicles present in the provided image.
The SAR data indicates normal activity at the Rostov-Southern-HQ facility. The low VH/VV ratio suggests limited off-road vehicle movement or deployment.
SAR data indicates a significant change in VV polarization (+4.5 dB) compared to the baseline, while the VH/VV ratio is -7.6 dB. This suggests a change in surface roughness or dielectric properties, potentially related to increased activity or equipment presence.
SAR data indicates moderate change at the Sevastopol naval facility, with a slight decrease in VV polarization and a low VH/VV ratio. This suggests some alteration in surface scattering characteristics, potentially related to ship movements or minor equipment changes.
The Baranovichi Air Base shows low activity. The runway is clear and there are few vehicles observed.
The SAR data indicates normal activity at the Grodno-garrison facility. The low VH/VV ratio suggests limited changes in surface roughness or vegetation.
SAR data indicates a significant change in VV polarization and a low VH/VV ratio, suggesting potential vehicle movement or changes in ground cover. The overall activity level is assessed as moderate due to these changes.
SAR data indicates normal activity at Severomorsk-NorthFleet. The polarimetric ratio suggests limited surface roughness or vegetation changes.
The SAR data indicates normal activity at the Osipovichi storage facility. The vehicle concentration appears low, and no aircraft are visible.
The SAR data indicates moderate change at the Kursk-Khalino airbase, with a slight increase in VV polarization. The runway appears clear, and there are few vehicles visible, suggesting routine operations or preparations for activity.
How sure we are
Last data: 2026-04-09 15:06 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.
