Satellite Coverage

Normal 2026-04-20

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

Before (2026-04-05) Latest (2026-04-18)
Grodno-garrison LOW activity

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.

Radar: No change Exposed ground detected Fuel activity 6%
Before (2026-04-06) Latest (2026-04-17)
Millerovo-airbase LOW activity

The SAR data indicates normal activity at Millerovo airbase. The low VH/VV ratio suggests minimal changes in surface roughness or vegetation.

Radar: Minor change Exposed ground detected Fuel activity 1%
Before (2026-04-06) Latest (2026-04-16)
Rostov-Southern-HQ LOW activity

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.

Radar: No change Exposed ground detected Fuel activity 22%
Before (2026-03-26) Latest (2026-04-16)
Tver-Migalovo LOW activity

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.

Radar: Minor change
Before (2026-03-21) Latest (2026-04-16)
Engels-2-strategic LOW activity

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.

Radar: No change Exposed ground detected Fuel activity 10%
Before (2026-04-14) Latest (2026-04-16)
Nizhny-Tagil-UVZ LOW activity

The SAR data indicates normal activity at the Nizhny-Tagil-UVZ facility. The vehicle concentration appears low, and no aircraft are visible.

Radar: No change Exposed ground detected Fuel activity 11%
Before (2026-04-05) Latest (2026-04-15)
Saki-Novofedorovka MODERATE activity

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.

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

Radar: Moderate change Fuel activity 8%
Before (2026-04-04) Latest (2026-04-14)
Klintsy-staging MODERATE activity

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.

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 and low vehicle concentration. The SAR data indicates normal activity levels.

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 to be low, and no aircraft are visible.

Radar: Minor change Exposed ground detected Fuel activity 2%
Before (2026-04-02) Latest (2026-04-14)
Ostrov-airbase LOW activity

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.

Radar: No change Exposed ground detected Fuel activity 2%

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.
