Pole Star delivers indoor location for safety and emergency response that works fully on-premise, even disconnected from shore.
Deployed with the world's largest cruise lines
What is cruise ship RTLS?
Cruise ship RTLS (Real-Time Location System) is the use of indoor positioning to locate passengers, crew and assets across the multiple decks of a cruise ship or vessel. It uses BLE badges and wristbands captured by the ship's existing onboard network, computed on a fully on-premise location engine, to support passenger safety, crew protection, CO2 mustering and emergency response - even with no connection to shore.
Safety-first shipboard location
Pole Star delivers kids tracking, CO2 mustering, emergency team tracking, medical alerts and asset tracking on multi-deck indoor maps.
Cruise lines and their teams
Cruise lines and maritime operators, safety officers and crew, and the passengers and children aboard large, complex vessels.
Ever-larger floating cities
Record-size vessels host thousands of people across many decks, with safety-critical technical zones and strict maritime and connectivity constraints.
BLE on a fully on-premise engine
BLE badges and wristbands on the existing onboard network, computed by an on-premise NAO® Track engine with real-time dashboards - autonomous, with no external connectivity.
Why location is critical aboard modern cruise ships
Public spaces, children's areas and technical zones operate simultaneously, making real-time visibility essential. Whether locating a child, responding to an incident or assisting crew members, accurate indoor positioning supports faster and safer operations.
Safety is especially critical in technical areas. Before a CO₂ fire-suppression system is activated, operators must confirm that everyone has evacuated. Real-time personnel localization and mustering provide the visibility needed to support these procedures.
Because connectivity at sea is limited, location services must operate fully on-premise, delivering reliable, low-latency positioning while protecting passenger privacy and supporting uninterrupted onboard operations.
The safety realities of running a floating city
Cruise ships concentrate passenger safety, crew protection and critical emergency operations into one complex, disconnected environment.
Child safety across a floating city
Keeping continuous visibility of children across huge, multi-deck ships with dedicated activity zones.
Vessel size, passenger volume and complex layouts exceed what manual supervision can cover.
Slower response and gaps in child safety and parental reassurance.
Personnel safety in CO2 zones and engine rooms
Before a CO2 system activates, teams must know exactly who is present and confirm evacuation.
Engine rooms and CO2-protected zones are among the highest-risk areas on board.
Without instant headcount, human risk rises during critical safety events.
Coordinating emergency teams across decks
Intervention teams must be located, mobilized and coordinated fast across many decks.
Complex, multi-deck vessels make manual coordination slow and error-prone.
Longer reaction times and weaker incident management.
Immediate medical assistance in public areas
Locating a passenger who needs help, or a defibrillator being accessed, without delay.
Public, high-traffic areas span many decks with no precise indoor location.
Delayed medical response when every second matters.
Safety systems with no link to shore
Critical safety operations must run reliably even when disconnected from shore.
Vessels operate under strict connectivity constraints across long voyages.
Cloud-dependent systems cannot be trusted for onboard safety.
Mustering and asset control during dry dock
Knowing who is on board, off, or at muster points, and controlling valuable assets during drydock.
Dry dock brings many contractors on board and expensive equipment into play.
Safety blind spots and asset losses during yard operations.
What Pole Star locates across the ship
Multi-deck & CO2 mustering
One location layer, from public decks to the engine room
BLE badges and wristbands are located on multi-deck maps in real time. In CO2-protected zones, Pole Star delivers instant headcount and evacuation status - all computed on-premise, with no link to shore.

Kids zones
Dedicated children's activity areas needing continuous, authorized-only visibility.
Engine rooms & CO2 zones
Highest-risk technical areas requiring headcount and verified evacuation.
Technical compartments
Crew-only spaces where precise personnel location supports safety procedures.
Muster points
Assembly zones where on-board, off-vessel and mustering status must be verified.
Medical & AED points
Locations where a defibrillator access or call button triggers an instant alert.
Real-time personnel monitoring in CO₂-protected zones and engine rooms
CO₂-protected zones and engine rooms are among the most critical environments onboard. Safety procedures require precise personnel location, instant headcount when an alarm is triggered, and a controlled and verified evacuation before any CO₂ system activation.
Without real-time visibility into personnel inside a CO₂-protected zone at the moment of an alarm, evacuation cannot be verified and the risk of activating the system while personnel are still present is real. Pole Star eliminates that uncertainty.
By providing immediate visibility into exposed personnel, automating headcount procedures, and monitoring evacuation progress in real time, Pole Star strengthens emergency control and significantly reduces human risk in CO₂-protected zones, entirely on-site and without reliance on external connectivity.
Real-time child safety across passenger areas
On large cruise ships, child safety is a critical concern due to the size of the vessels, the high number of passengers and the complexity of indoor layouts - multiple decks and dedicated activity zones where traditional supervision alone cannot guarantee continuous visibility or rapid response.
Pole Star enables real-time kids tracking through wearable BLE bracelets designed for children. Positions are visualized on multi-deck indoor maps and refreshed continuously, with access restricted to authorized users only.
Designed to operate at very large scale, the solution supports thousands of bracelets per voyage, delivering low-latency performance and reinforcing both child safety and parental reassurance - without impacting the onboard experience.
The same emergency, before and after real-time location
Roll call runs over radio, with no certainty that every crew member has left the zone before activation.
A CO2 mustering dashboard shows a live headcount inside the zone and real-time evacuation progress.
Verified evacuation and reduced human risk during a critical safety event.
Supervision relies on line of sight across a floating city, and locating a child who wanders is slow.
The child's wristband shows on multi-deck maps, visible to the parent in the app, with zone alerts on entry or exit.
Continuous child safety and genuine parental reassurance.
A call for help gives no precise location, so the medical team searches across multiple decks.
A geolocated Help button, or a defibrillator being accessed, transmits the exact position instantly to medical teams.
Faster medical assistance and stronger passenger safety.
Teams are coordinated by radio, with unclear positions across many decks and zones.
A centralized view shows every emergency team's position live, with badge-triggered alerts and coordinated deployment.
Faster, better-coordinated incident response, scalable across ships.

Built for the constraints of a ship at sea
A cruise vessel is a safety-critical environment with strict connectivity, privacy and operational limits. The platform is designed to run inside those limits rather than around them - fully onboard, on the network you already have.
Fully on-premise, offline by design
The BLE positioning engine runs on an on-premise NAO® Track server aboard the ship. It keeps working with no external connectivity - critical for a vessel that spends days away from shore-side networks.
Runs on the existing onboard network
Positioning is computed over the Wi-Fi access points already installed for onboard connectivity. No heavy new cabling or parallel network is added to certified ship systems.
Dense steel, many decks, no GNSS
Satellite positioning does not work below deck. The system is engineered for a multi-deck steel environment with safety-critical technical zones such as engine rooms and CO₂ areas.
Passenger & child data stays onboard
Because computation is fully on-premise, tracking data for passengers and children on BLE wristbands never leaves the vessel - a privacy-by-design posture for sensitive onboard data.
What real-time location changes onboard
One live operational picture across every deck - for safety officers, crew and the people they are responsible for. No new network, no dependence on shore-side connectivity.
See every deck in real time
