Defense Satellite Intelligence From Open Sources
Unclassified, open-source GEOINT for the defense and security community: track conflicts and crises, verify open-source claims with Sentinel imagery, and get sourced, caveated AI briefs — for situational awareness and verification, not targeting.
Quick Answer: Open-source defense intelligence builds security-relevant assessments from publicly available sources — open reporting plus commercial and free satellite imagery — for situational awareness and verification, not classified collection or targeting. Off-Nadir Delta supports that workflow: a global open-source event feed, Sentinel SAR and optical imagery you can pull over any event, and an AI analyst that returns sourced, confidence-caveated briefs. Open sources only; no surveillance of individuals.
The scope, stated plainly
What this is for
- Situational awareness of conflicts and crises from open sources
- Verifying and corroborating open-source claims with imagery
- Monitoring areas of interest over time
- Sourced, confidence-caveated analytic briefs
What it is not
- Not a classified system — open sources only
- Not an operational targeting tool
- Not for the surveillance of individuals
- Not a claim to resolve what the imagery cannot
Open-Source Feed
A continuously refreshed global event feed, geolocated and severity-ranked — the open-source tip.
SAR & Optical
Cue Sentinel-1 radar through cloud and darkness, or Sentinel-2 optical for visual confirmation.
Caveated Briefs
An AI analyst that states what imagery can and cannot show, with confidence calibrated, not asserted.
Verifiable
Every finding is sourced and located, so assessments can be shown, shared, and independently checked.
Within Resolution
Detect-versus-identify is respected — no claiming to read at ~10 m what only sub-metre imagery can resolve.
No GIS Stack
Runs in the browser. Browse the picture free; no install and no code to get started.
How It Works
Watch the open-source picture
Start with a continuously refreshed feed of geolocated geopolitical and security events worldwide, ranked by severity — the open-source tip that something has happened.
Cue the imagery
Pull Sentinel-1 SAR or Sentinel-2 optical over a located event. Radar sees through cloud and at night; optical confirms visually — choose the sensor the question needs.
Get a sourced, caveated brief
Ask the AI analyst why an event matters and what the imagery can and cannot show, with confidence calibrated to a single pass, geometry, or resolution — not asserted.
Monitor the area
Save the area and track it over time so force posture, construction, or activity changes surface as anomalies rather than something you must catch by eye.
