Satellite Coverage

Normal 2026-04-14

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

Before (2026-04-04) Latest (2026-04-14)
Klintsy-staging MODERATE activity

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.

Radar: Significant 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 polarimetric ratio suggests limited scattering from complex structures, consistent with a storage facility in a routine operational state.

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 shows an urban area, likely near the Nizhny-Tagil-UVZ facility. Vehicle concentration appears low, and no aircraft are visible.

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 a slightly elevated VV polarization. No aircraft or vehicles are visible on the runway or surrounding areas, suggesting a low level of activity.

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 no aircraft observed on the runway. Vehicle concentration appears low, suggesting routine operations.

Radar: No change Exposed ground detected Fuel activity 1%
Before (2026-04-01) Latest (2026-04-11)
Gusev-garrison LOW activity

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.

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 surface roughness changes, and vehicle concentration appears low.

Radar: Minor change Fuel activity 6%
Before (2026-04-05) Latest (2026-04-11)
Olenya-airbase LOW activity

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.

Radar: Minor change Fuel activity 1%
Before (2026-04-02) Latest (2026-04-10)
Luga-6th-CAA MODERATE activity

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.

Radar: No change Exposed ground detected Fuel activity 3%
Before (2026-04-02) Latest (2026-04-10)
Kronstadt-naval MODERATE activity

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.

Radar: Moderate change Exposed ground detected Fuel activity 5%
Before (2026-04-02) Latest (2026-04-10)
Kamenka-138th-MRB LOW activity

SAR data indicates normal activity at the Kamenka-138th-MRB facility. The low VH/VV ratio suggests minimal changes in surface roughness or vegetation.

Radar: Minor change Exposed ground detected Fuel activity 12%
Before (2026-04-02) Latest (2026-04-10)
Levashovo-airbase LOW activity

The satellite image of Levashovo airbase shows no aircraft on the runway and a low vehicle concentration. The SAR data indicates normal activity levels.

Radar: Minor change Exposed ground detected Fuel activity 9%

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.
