ESA Sentinel-1 · maritime screening beta

Maritime SAR intelligence for teams without a satellite desk.

Screen shipping corridors with open Sentinel-1 radar, AIS support metadata, SAR overlays, and optical context — all via API. Start with a renewable monthly free tier, then escalate high-value cases to the separate Intelligence scan workflow.

Every maritime Sentinel-1 overpass.
Queryable in milliseconds.

This is the screening layer: ESA's Sentinel-1 C-band radar satellites image the oceans every 6–12 days in all weather. We process those scenes, attach AIS support context, and serve them via API for maritime monitoring, triage, and historical analysis. Exact-time investigations stay separate in the Intelligence tier.

Maritime screening first.
Everything else stays secondary.

Query maritime scenes, vessel candidates, AIS support, and SAR/optical overlays from a single API. The launch focus is shipping corridors and chokepoints; other detection layers remain experimental until their data density and quality are proven.

🚢
Maritime screening API
Screen ship-like radar targets through cloud, fog, and darkness. Returns GeoJSON with scene IDs, confidence, timestamps, and vessel metadata ready for triage.
🧭
AIS support metadata
Each maritime result carries explicit AIS support levels, nearest-source context, and gap-zone flags so users can see what is matched, partial, or investigation-grade.
🛰️
SAR + optical scene overlays
Inspect recent Sentinel-1 VV/VH swaths and pre-ingested Sentinel-2 true-color context directly on the map so analysts can understand what the scene actually looked like.
🎯
Intelligence scans
Escalate specific cases to fresh commercial SAR with exact-time AIS correlation. Built for sanctions, dark-vessel, chokepoint, and investigation-grade customer requests.
📡
Webhook subscriptions
Subscribe to maritime detections over chokepoints, ports, or customer AOIs. We POST new results after each processed scene so teams can automate follow-up without polling.
Experimental non-maritime layers
Flood, sea ice, burn scar, deforestation, construction, and oil spill remain in the platform, but they are not the commercial center of the product until quality and density catch up.
Intelligence tier

Exact-time investigations.
Task a satellite. Pay once.

This tier is separate from the Sentinel-1 screening API. For sanctions evasion, illicit ship-to-ship transfers, and illegal fishing investigations, we task a commercial SAR satellite (ICEYE, Capella, or Umbra), correlate detections against AIS coverage at the exact acquisition time, and return a fresh investigation report with matched, unmatched, and AIS-gap context.

$999 per scan
  • Commercial SAR satellite tasked on payment — results in 24–48h
  • AIS correlation at exact SAR acquisition time (±30 min window)
  • Sanctions database cross-reference on all matched vessels
  • Results delivered via webhook + queryable via API
  • Covers Red Sea, Suez, Hormuz, and all ocean areas

Built for maritime teams that need
answers, not raw radar.

The launch product is maritime screening plus exact-time investigations. That keeps the workflow self-serve while staying honest about where the strongest data and quality sit today.

🛡️
Sanctions & compliance teams
Monitor sanctioned vessels in the Red Sea, Hormuz Strait, and Russian Arctic routes. Detect AIS-dark ships engaged in sanctions evasion or illicit STS transfers.
Ports & shipping operations
Monitor approach lanes, congestion, and vessel activity around strategic ports and chokepoints without having to build a SAR + AIS stack in-house.
📡
Maritime intelligence
Screen recent SAR scenes, inspect overlays, and escalate exact-time dark-vessel or suspicious-vessel cases only when they justify the premium workflow.
📰
NGOs & investigative teams
Use maritime screening as a low-cost lead generator, then order a specific Intelligence scan when a sanctions, illegal fishing, or conflict case needs stronger evidence.
🛢️
Energy & commodity desks
Follow strategic routes around the Red Sea, Hormuz, and West Africa, then trigger an exact-time investigation when a cargo, tanker, or transshipment case matters.
💻
Developer platforms
Embed maritime SAR screening, SAR overlays, and AIS support metadata into your own product without making your users become remote-sensing specialists.

Maritime incumbents charge enterprise prices
for workflows smaller teams still need.

The point is not to outspend enterprise maritime intelligence vendors. The point is to give smaller teams a self-serve screening product and a clear path to exact-time investigations.

Stay in screening
Use monthly plans for monitoring, historical context, wide-area triage, webhook alerts, and day-to-day customer workflows.
Trigger Intelligence
Escalate when the customer needs exact-time evidence, the scene is coastal or high-clutter, or the case is sanctions, conflict, insurance, or chokepoint monitoring.
AIS policy
Baseline Tidewatch AIS supports screening by default. Premium AIS is reserved for Red Sea, Suez, Hormuz, and other high-consequence cases where coverage quality is not strong enough.
Simple customer story
SAR API Screening for routine monitoring. SAR API Intelligence for exact-time investigations. One product family, two confidence levels, clear escalation path.
