Satellite Coverage

Normal 2026-04-21

Summary

Satellite analysis fresh (latest 2026-04-20 15:01:49 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 activity
Radar: No change Exposed ground detected Fuel activity 6%
Before (2026-04-06) Latest (2026-04-17)
Millerovo-airbase activity
Radar: Minor change Exposed ground detected Fuel activity 1%
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 polarimetric ratio suggests no significant changes in surface roughness or scattering characteristics.

Radar: Minor change

Sevastopol-naval activity
Radar: No change Fuel activity 8%
Before (2026-04-04) Latest (2026-04-14)
Osipovichi-storage LOW activity

The SAR data indicates normal activity at the Osipovichi storage facility. The VH/VV ratio suggests limited metallic scattering, and the vehicle concentration appears low.

Radar: Minor change Exposed ground detected Fuel activity 2%

Baranovichi-Belarus activity
Radar: No change Fuel activity 2%
Before (2026-04-04) Latest (2026-04-14)
Klintsy-staging activity
Radar: No change Exposed ground detected Fuel activity 3%
Before (2026-04-02) Latest (2026-04-14)
Ostrov-airbase activity
Radar: No change Exposed ground detected Fuel activity 2%

How sure we are

Last data: 2026-04-20 15:01 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.

Primary source: Copernicus Sentinel-2 / Sentinel-1
