Satellite Coverage
Summary
Satellite analysis fresh (latest 2026-04-14 15:03:52 UTC).
Why this matters
Activity at military sites — vehicle movement, construction, equipment staging — can indicate preparation, rotation, or capability changes.
What we saw
SAR data indicates a significant change in VV polarization (+3.6 dB) and a low VH/VV ratio (-9.4 dB), suggesting increased activity and potentially the presence of metallic objects. Vehicle concentration is moderate, and the overall activity level is assessed as moderate.
The SAR data indicates normal activity at the Osipovichi storage facility. The polarimetric ratio suggests limited scattering from complex structures, consistent with a storage facility in a routine operational state.
The satellite image shows an urban area, likely near the Nizhny-Tagil-UVZ facility. Vehicle concentration appears low, and no aircraft are visible.
The Ostrov airbase shows normal SAR activity with a slightly elevated VV polarization. No aircraft or vehicles are visible on the runway or surrounding areas, suggesting a low level of activity.
The Chernyakhovsk airbase shows normal SAR activity with no aircraft observed on the runway. Vehicle concentration appears low, suggesting routine operations.
SAR data indicates normal activity at Gusev-garrison. The polarimetric ratio suggests limited cross-polarization scattering, consistent with a lack of significant vehicle movement or deployment.
SAR data indicates normal activity at Severomorsk-NorthFleet. The polarimetric ratio suggests limited surface roughness changes, and vehicle concentration appears low.
The SAR data indicates normal activity at Olenya airbase. No aircraft are visible on the runway or in the immediate vicinity, and vehicle concentration appears to be minimal.
SAR data indicates significant change at the facility, with a notable decrease in VV polarization and a low VH/VV ratio. This suggests potential changes in surface roughness or dielectric properties, possibly related to vehicle movement or equipment changes.
SAR data indicates moderate change at the Kronstadt naval facility, with a slight increase in VV polarization and a low VH/VV ratio. This suggests potential changes in surface roughness or dielectric properties, possibly related to vehicle movement or equipment changes.
SAR data indicates normal activity at the Kamenka-138th-MRB facility. The low VH/VV ratio suggests minimal changes in surface roughness or vegetation.
The satellite image of Levashovo airbase shows no aircraft on the runway and a low vehicle concentration. The SAR data indicates normal activity levels.
How sure we are
Last data: 2026-04-15 15:07 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.
