Satellite Coverage
Summary
Satellite analysis fresh (latest 2026-04-19 15:04:07 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 Grodno-garrison, with VV polarization near baseline and a low VH/VV ratio. Vehicle concentration appears low, suggesting routine operations.
The SAR data indicates normal activity at Millerovo airbase. The low VH/VV ratio suggests minimal changes in surface roughness or vegetation.
SAR data indicates normal activity at the Rostov-Southern-HQ facility. The low VH/VV ratio suggests limited scattering from vertical structures, and the vehicle concentration appears low.
The SAR data indicates normal activity at the Tver-Migalovo military facility. The VV polarization is slightly elevated, while the VH/VV ratio suggests minimal cross-polarization scattering.
The Engels-2 strategic airbase shows moderate SAR change with a VV decrease of 1.3 dB and a VH/VV ratio of -7.7 dB, suggesting some activity but no aircraft are visible on the runway. The runway appears clear and vehicle concentration is low.
The SAR data indicates normal activity at the Nizhny-Tagil-UVZ facility. The vehicle concentration appears low, and no aircraft are visible.
SAR radar indicates a significant change in VV polarization (+4.4 dB) compared to the baseline, while the VH/VV ratio is -5.4 dB. The runway appears clear, and there are a few vehicles visible, suggesting moderate activity.
SAR data indicates a moderate change in activity at the Sevastopol naval facility. The polarimetric ratio suggests some changes in surface scattering characteristics, potentially related to vessel movements or minor equipment changes.
Significant SAR change (VV -4.4 dB) and a low VH/VV ratio (-13.5 dB) suggest increased activity at the Klintsy staging area. This could indicate the arrival of vehicles and equipment, potentially related to military operations or training.
The satellite image of Baranovichi Air Base shows a clear runway and low vehicle concentration. The SAR data indicates normal activity levels.
The SAR data indicates normal activity at the Osipovichi storage facility. The vehicle concentration appears to be low, and no aircraft are visible.
The Ostrov airbase shows normal SAR activity with a VV value close to baseline and a VH/VV ratio of -5.7 dB. The runway is clear, and there are few vehicles visible, suggesting a low level of activity.
How sure we are
Last data: 2026-04-19 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.
