Satellite Coverage
Summary
Satellite analysis fresh (latest 2026-04-13 15:04:05 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 normal activity at Severomorsk-NorthFleet. The polarimetric ratio suggests limited scattering from complex structures, indicating a lack of significant vehicle or equipment movement.
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.
The satellite image of Chernyakhovsk airbase shows a low level of activity. The runway is clear and there are few vehicles visible.
The SAR data indicates normal activity at the Gusev-garrison military facility. The low VH/VV ratio suggests limited vegetation or rough surfaces.
SAR data indicates moderate change at the Kamenka-138th-MRB facility, with a VV increase of +1.5 dB and a VH/VV ratio of -3.7 dB, suggesting a possible increase in vehicle presence. The overall activity level is assessed as moderate based on these changes.
The satellite image of Machulishchy Air Base shows a clear runway with no aircraft visible. The low vehicle concentration and normal SAR radar activity suggest a low overall activity level at the facility.
SAR radar shows normal activity with a slight increase in VV polarization. The VH/VV ratio suggests limited scattering from vertical structures.
The satellite image of Pskov-76th-VDV shows a clear runway and low vehicle concentration. SAR data indicates normal activity levels.
The satellite image of Levashovo airbase shows a clear runway and low vehicle concentration. SAR radar data indicates normal activity with VV +0.1 dB vs baseline and VH/VV polarimetric ratio of -7.9 dB.
The SAR data indicates normal activity at the Kronstadt naval facility. The polarimetric ratio suggests limited scattering from complex structures, consistent with routine operations.
SAR data indicates normal activity at the Luga-6th-CAA facility. The VH/VV ratio suggests limited changes in surface roughness or orientation, consistent with routine operations.
SAR data indicates moderate change at the Donskoye missile facility, with a slight decrease in VV polarization and a low VH/VV ratio. This suggests possible movement or repositioning of equipment, but could also be due to environmental factors.
How sure we are
Last data: 2026-04-13 15:04 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.
