About TwoBlue
What is TwoBlue?
TwoBlue is the software of X-MAS: five modules (Nereus, Poseidon, Trident, Zeus and Labrador), the Nereus Data Handling System and four emulators. Together they share one ocean model and one interface.
How do the TwoBlue modules work together?
Nereus models the ocean. Poseidon plans the mission and commands the fleet. Trident runs it at sea and Zeus in the air. Labrador senses at the edge and fuses every source into one contact picture.
Which platforms does TwoBlue run on?
Trident runs on UUVs, USVs, buoys and seabed nodes. Zeus runs on fixed-wing and multirotor UAVs. Poseidon runs on a C2 console or a rugged laptop in the field.
Does TwoBlue connect to our own C2?
Yes. Poseidon has external C2 interfaces, and the Data Handling System serves Poseidon and your own C2 from the same store.
Can we try TwoBlue before going to sea?
Yes. The Trident Vessel, Zeus Aircraft, Labrador Array Placement and Labrador Array Performance emulators let teams train, test and integrate before any hardware gets wet or flies.
Are the screens on this website from real missions?
No. They come from TwoBlue software running demo scenarios with simulated and emulated data, and the scenarios and animations are illustrative.
Where is Xaltcraft based?
In Nova Scotia, Canada. Xaltcraft is Canadian owned and Canadian operated.
How do I see TwoBlue running?
Ask for a live demo, or a call with the team that builds it.
TwoBlue · Buying and integration
Buying and integration
Can TwoBlue systems be procured separately?
Yes. TwoBlue is designed to work as one system or as individual modules.
How can TwoBlue be procured?
As an annual licence per module, a perpetual licence per seat, or on terms we agree with you.
Which protocols and standards does TwoBlue support?
Certification and compliance with the standards you need can be agreed with you.
Who owns the intellectual property?
All intellectual property is held by Xaltcraft.
Can TwoBlue work with our existing sensors, platforms and networks?
Yes. TwoBlue is designed to be equipment agnostic. With access to the relevant protocols, TwoBlue can also take over legacy systems.
Can TwoBlue work where communications are limited?
Yes. Vehicles keep working the mission when the link drops, hold their reports on board and send them at the next comms window.
Do you provide training and support?
Yes. Operator training, including AR training and interactive manuals, plus repairs and annual maintenance contracts. See Lifecycle support and training.
TwoBlue · Data and control
Data and control
Where does TwoBlue’s data come from?
TwoBlue uses publicly available data only. Specific data sources can be enabled or disabled to suit each customer’s requirements.
Does TwoBlue use classified data?
No. TwoBlue uses only publicly available, unclassified data.
Can TwoBlue use classified data?
Yes. Data sources can be customised to each customer’s requirements.
Do Xaltcraft or TwoBlue use customer data to train models?
No. Xaltcraft and TwoBlue do not store or use customer data to train models. If a customer wants this, it can be added as an extra feature.
Can TwoBlue override the operator’s instructions?
No. TwoBlue is designed with a human in the loop, and manual orders override the autonomous algorithms.
TwoBlue · Nereus
Nereus
What is Nereus?
Nereus is TwoBlue’s digital ocean model. It brings the seabed, the water column and the surface into one live model and serves each mission the data it needs.
Which ocean data does Nereus include?
Bathymetry, temperature, salinity, currents, sea state, wave period, sediment, and ambient and shipping noise, on one 3D globe, with sound-speed profiles for acoustic planning.
Can every planning decision be traced to its data?
Yes. Nereus keeps dated snapshots, so a decision can be traced back to the exact data it used.
TwoBlue · Data Handling System
Data Handling System
What does the Data Handling System do?
It takes in mission and sensor data from vehicles, sensors and feeds, checks it, stores it, archives dated snapshots and replays any of them on request.
Is the data stored securely and redundantly?
Yes. Data is held on redundant database servers and moves between sea and shore on Xaltcraft’s own protocols.
Who can use the data?
Poseidon and your own C2 retrieve it from the same store.
TwoBlue · Poseidon
Poseidon
What does Poseidon do?
Poseidon plans and commands missions for sensors and autonomous platforms: environment assessment, sensor placement, tactical routing and deconfliction, from one console.
How many platforms can Poseidon command?
Up to 9 platforms today, scalable to 2,000.
How does Poseidon handle sound speed?
It plans with sound-speed profiles built ashore from Nereus and updated live at sea from on-board sound velocity sensors.
TwoBlue · Trident
Trident
What is Trident?
Trident runs the Poseidon mission on board UUVs, USVs, buoys and seabed nodes, and adapts within the limits it was given.
Does Trident follow the Rules of the Road?
Yes. Its anti-collision follows the Rules of the Road (COLREGs) while it keeps to the mission.
Does Trident need GPS?
Trident decides its own route and next waypoint. The vehicle’s position comes from GPS, AIS or other navigation aids.
What happens when communications are poor?
Trident keeps working the mission, holds its reports on board and sends them at the next comms window.
TwoBlue · Zeus
Zeus
What is Zeus?
Zeus brings the TwoBlue mission engine to fixed-wing and multirotor UAVs, from take-off to landing at HOME.
How does Zeus stay safe in the air?
It gives way under the rules of the air, stays inside geofences with floors and ceilings, and has energy, geofence, lost-link and equipment-fault fail-safes.
Can Zeus work with Trident?
Yes. Both take their missions from Poseidon, which keeps air and sea deconflicted.
TwoBlue · Labrador
Labrador
What is Labrador?
Labrador is TwoBlue’s sensing system at the edge. It fuses acoustic, magnetic, optical, radar, AIS and other feeds into one contact picture.
Can Labrador track contacts passively?
Yes. It holds up to ten contacts at once with passive target motion analysis, with no active transmission.
Does Labrador classify vessels?
Yes. Automatic DEMON classification picks out a ship’s propeller and classifies the vessel with a stated confidence.
TwoBlue · Emulators
Emulators
Which emulators are available?
The Trident Vessel Emulator, Zeus Aircraft Emulator, Labrador Array Placement Emulator and Labrador Array Performance Emulator.
Do I need hardware to start?
No. Teams can train, test and integrate before any hardware gets wet or flies.
Can each emulator be bought on its own?
Yes. Each one can be bought on its own, or all four together.
