Satellite Coverage

Normal 2026-04-08

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

Before (2026-03-25) Latest (2026-04-06)
Rostov-Southern-HQ MODERATE activity

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.

Radar: No change Exposed ground detected Fuel activity 22%
Before (2026-03-25) Latest (2026-04-06)
Morozovsk-airbase MODERATE activity

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.

Radar: No change Exposed ground detected
Before (2026-03-25) Latest (2026-04-06)
Millerovo-airbase LOW activity

The SAR radar data indicates normal activity at Millerovo airbase. The runway appears clear and there are few vehicles visible.

Radar: No change Exposed ground detected Fuel activity 1%
Before (2026-03-13) Latest (2026-04-05)
Sevastopol-naval MODERATE activity

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.

Radar: No change Fuel activity 8%
Before (2026-03-16) Latest (2026-04-05)
Saki-Novofedorovka MODERATE activity

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.

Radar: Significant change Fuel activity 4%
Before (2026-03-27) Latest (2026-04-04)
Klintsy-staging MODERATE activity

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.

Radar: No change Exposed ground detected Fuel activity 2%
Before (2026-04-03) Latest (2026-04-04)
Severomorsk-NorthFleet LOW activity

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.

Radar: No change Fuel activity 4%
Before (2026-03-16) Latest (2026-04-03)
Brest-garrison LOW activity

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.

Exposed ground detected Fuel activity 4%
Before (2026-03-15) Latest (2026-04-02)
Ostrov-airbase LOW activity

The Ostrov airbase shows a low level of activity. The runway is clear and there are few vehicles visible.

Radar: No change Exposed ground detected Fuel activity 1%
Before (2026-03-18) Latest (2026-04-02)
Strugi-Krasnye LOW activity

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.

Radar: Minor change Exposed ground detected
Before (2026-03-27) Latest (2026-04-01)
Chernyakhovsk-airbase LOW activity

The Chernyakhovsk airbase shows low activity. The runway is clear and there are few vehicles observed.

Radar: Minor change Exposed ground detected
Before (2026-03-27) Latest (2026-04-01)
Gusev-garrison LOW activity

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

Radar: No change Exposed ground detected Fuel activity 3%

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.
