Satellite Coverage
Summary
Satellite analysis fresh (latest 2026-04-07 15:07:49 UTC).
Why this matters
Activity at military sites — vehicle movement, construction, equipment staging — can indicate preparation, rotation, or capability changes.
What we saw
The SAR data indicates moderate change at the Rostov-Southern-HQ facility, with a slight decrease in VV polarization and a low VH/VV ratio. Vehicle concentration appears low, suggesting a possible shift in activity but not a major deployment.
The Morozovsk airbase shows moderate change in SAR radar data, with a VV change of -1.7 dB and a VH/VV ratio of -11.2 dB, suggesting some activity but no readily identifiable aircraft. The low vehicle concentration suggests limited ground activity.
The SAR radar data indicates normal activity at Millerovo airbase. The runway appears clear and there are few vehicles visible.
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 potential movement or rearrangement of assets within the facility.
SAR data indicates a significant change in VV polarization (+5.4 dB) compared to the baseline, while the VH/VV ratio is -7.7 dB. This suggests some activity, but the absence of visible aircraft and low vehicle concentration indicates it is not at peak operational capacity.
Significant change detected via SAR radar (VV -5.2 dB) and a VH/VV polarimetric ratio of -9.5 dB suggests a change in the scattering characteristics of the area, potentially due to vehicle movement or changes in ground cover. The vehicle concentration is assessed as moderate.
SAR data indicates normal activity at Severomorsk-NorthFleet, with a slight increase in VV polarization and a low VH/VV ratio. The runway appears clear and there are few vehicles visible.
The Brest-garrison facility shows a low level of activity. There are a few vehicles present, but no aircraft are visible and the runway status is unknown.
The Ostrov airbase shows a low level of activity. The runway is clear and there are few vehicles visible.
SAR data indicates normal activity with a slight increase in VV polarization. The VH/VV ratio suggests minimal changes in surface roughness or vegetation scattering.
The Chernyakhovsk airbase shows low activity. The runway is clear and there are few vehicles observed.
SAR data indicates normal activity at Gusev-garrison. The low VH/VV ratio suggests limited changes in surface roughness or vegetation.
How sure we are
Last data: 2026-04-07 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.
