Satellite Coverage

Normal 2026-04-17

Summary

Satellite analysis fresh (latest 2026-04-16 15:07:15 UTC).

Why this matters

Activity at military sites — vehicle movement, construction, equipment staging — can indicate preparation, rotation, or capability changes.

What we saw

Before (2026-04-05) Latest (2026-04-15)
Saki-Novofedorovka MODERATE activity

SAR data indicates a significant change in VV polarization (+4.0 dB) compared to the baseline, while the VH/VV ratio is -6.2 dB, suggesting increased surface roughness or the presence of new scatterers. The runway appears clear, and there are few vehicles visible, but the SAR change suggests moderate activity.

Radar: Significant change Fuel activity 4%
Before (2026-04-05) Latest (2026-04-15)
Sevastopol-naval LOW activity

SAR data indicates normal activity at the Sevastopol naval facility. The polarimetric ratio suggests limited changes in surface roughness or orientation.

Radar: No change Fuel activity 8%
Before (2026-04-04) Latest (2026-04-14)
Klintsy-staging MODERATE activity

SAR data indicates a significant change in VV polarization and a low VH/VV ratio, suggesting increased activity at the Klintsy staging area. The vehicle concentration is assessed as moderate based on the SAR signature.

Radar: No change Exposed ground detected Fuel activity 3%
Before (2026-04-05) Latest (2026-04-14)
Baranovichi-Belarus LOW activity

The satellite image of Baranovichi Air Base shows a clear runway with no visible aircraft. SAR data indicates normal activity levels, suggesting routine operations.

Radar: No change Exposed ground detected Fuel activity 3%
Before (2026-04-04) Latest (2026-04-14)
Osipovichi-storage LOW activity

The SAR data indicates normal activity at the Osipovichi storage facility. The vehicle concentration appears low, and no aircraft are observed.

Radar: No change Exposed ground detected Fuel activity 2%
Before (2026-03-30) Latest (2026-04-14)
Nizhny-Tagil-UVZ LOW activity

The satellite image of Nizhny-Tagil-UVZ shows a low level of activity. There are few vehicles visible and no aircraft are present.

Exposed ground detected Fuel activity 10%
Before (2026-04-02) Latest (2026-04-14)
Ostrov-airbase LOW activity

The Ostrov airbase shows normal SAR activity with no visible aircraft or vehicles on the runway or surrounding areas. The runway appears clear, suggesting routine operations or a period of inactivity.

Radar: Minor change Exposed ground detected Fuel activity 1%
Before (2026-04-01) Latest (2026-04-11)
Chernyakhovsk-airbase LOW activity

The Chernyakhovsk airbase shows normal SAR activity with a low polarimetric ratio. The runway is clear, and there are few vehicles observed, indicating a low overall activity level.

Radar: No change Exposed ground detected Fuel activity 1%
Before (2026-04-05) Latest (2026-04-11)
Olenya-airbase LOW activity

The SAR data indicates normal activity at Olenya airbase, with a slight increase in VV polarization and a low VH/VV ratio. The runway appears clear and no aircraft are visible in the image.

Radar: Minor change Fuel activity 1%
Before (2026-04-01) Latest (2026-04-11)
Gusev-garrison LOW activity

The SAR data indicates normal activity at Gusev-garrison. The VH/VV ratio suggests limited changes in surface roughness or vegetation scattering.

Radar: No change Exposed ground detected Fuel activity 3%
Before (2026-04-04) Latest (2026-04-11)
Severomorsk-NorthFleet LOW activity

SAR data indicates normal activity at Severomorsk-NorthFleet. The polarimetric ratio suggests limited new scattering events.

Radar: Minor change Fuel activity 6%
Before (2026-04-02) Latest (2026-04-10)
Kronstadt-naval MODERATE activity

SAR data indicates a moderate change in activity at the Kronstadt naval facility. The moderate VV increase suggests some new or repositioned metallic structures, while the VH/VV ratio suggests limited cross-polarization scattering, possibly due to vehicle movement or minor equipment changes.

Radar: Moderate change Exposed ground detected Fuel activity 5%

How sure we are

Last data: 2026-04-16 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.
