MotionInfo's StationKeeper transmits AIS safety messages from shore aids-to-navigation to vessels underway,
putting near-real-time North Atlantic right whale information directly on vessel bridges. This portal collects our
public-facing compliance reports, live at-sea testing analysis, and the key reference documents behind the program.
Compliance Reports
Current — Full Season
Single-Message Incident Review — Full Season
All 861 trackable single-message StationKeeper overspeed encounters, true full-season population (1,515 vessels
messaged, 11,370 total dispatches). Per-incident nautical charts and speed-over-time graphs, vessel name, AIS type,
message-received markers, split by corridor.
Ambient vessel speed in NARW SMA corridors compared in-season vs out-of-season, with 108 example vessel
movement tracks and a full vessel table, alongside messaged-incident pre-trigger speeds.
Live delivery-receipt ranges to research vessels and the NOAA Ship Nancy Foster (out to ~15–16 nm), plus an audit of real, unsolicited Message 12 acknowledgements from commercial and pilot-guided vessels — including the TS State of Maine, sent from Navesink (Twin Lights) Lighthouse.
StationKeeper AIS Messaging Tests — Delivery-Receipt Range Results
Prepared for the NOAA AIS Messaging Technical Implementation Workgroup · July 2026
"StationKeeper delivered AIS safety messaging from shore aids-to-navigation to vessels underway,
displayed identically across every major chartplotter brand, with delivery receipts confirmed over the vessels'
actual operating ranges and a two-way exchange demonstrated end to end. The messaging capability NOAA is
evaluating works on real vessels, at sea, today."
— Conclusion. Six vessels reached (incl. NOAA Ship Nancy Foster); receipts confirmed to ~15–16 nm; two-way round trip with TS State of Maine.
AIS safety messages received and displayed live across a full bench of marine electronics —
Furuno, Simrad, Garmin and VHF — confirming the same message renders identically regardless of the vessel's
installed brand.
— Test bench demonstration accompanying the delivery-receipt range tests.
Regulatory speed messages · Dynamic Management Areas · individual-sighting ring protocol
"Deliver concise, location-specific AIS safety messages directly to vessel wheelhouses when
regulatory conditions or whale-presence information indicate elevated collision risk."
— Purpose statement. Includes the proposed 5 / 10 / 20 NM, 1 / 3 / 6-hour individual-sighting alert protocol put to the U.S. Coast Guard.
NOAA Fisheries · Arlington, VA · March 5–6, 2024 — full presentation portfolio, including MotionInfo's session
"AIS can support NOAA Seasonal Management Areas (SMA) and Dynamic Management Areas (DMA)
with real-time alerts to mariners … [and] can automatically reach most 65 ft+ vessels, today."

IMO SN.1/Circ.289 — Guidance on the Use of AIS Application-Specific Messages
International Maritime Organization · 2 June 2010
The internationally recommended framework for AIS Application-Specific Messages — the standard
under which shore-to-ship safety and geographic-notice messaging operates.
— The foundational IMO guidance StationKeeper's messaging conforms to.
Messaging Mariners in Real Time to Reduce Right Whale Vessel Strikes
NOAA Fisheries feature story
"A new real-time messaging network uses a well-established maritime navigation safety
technology — the Automatic Identification System — to reduce North Atlantic right whale vessel strikes."
— NOAA Fisheries feature on the AIS alert network.
On-vessel documentation with UNH CCOM & marine operations · July 2026
Right-whale slow-zone AIS safety messages transmitted from the Portsmouth Lighthouse and
documented rendering natively on UNH research-vessel displays (Garmin, RosePoint Coastal Explorer).
— Photo & video captured aboard the Tego and R/V Gulf Challenger.
Shore-to-ship and ship-to-shore round trip · New York Harbor · July 2026
Addressed AIS safety messages transmitted from shore aids-to-navigation, received aboard the
Maine Maritime Academy training ship TS State of Maine (Furuno Class-A AIS), with the vessel's acknowledgement
received back at the shore station — a complete two-way exchange.
— Photos captured aboard by the ship's Cadet Public Relations Officer.
Five vessels reached — R/V Sharp, Palmetto, Joanne Daiber, Savannah & NOAA Ship Nancy Foster · July 2026
AIS safety messages sent from shore aids-to-navigation to research vessels underway, with delivery
receipts confirmed back at StationKeeper stations from close aboard out to ~15–16 nm — plus a two-way ACK from the
R/V Savannah. Includes each vessel's photo, specifications, and per-vessel receipt data.
— Companion to the delivery-receipt range testing report.
MotionInfo's StationKeeper right-whale safety-messaging program is developed in collaboration with conservation, marine-sanctuary, and lighthouse-stewardship organizations across the U.S. East Coast.
