ZeroNorth and Spire Maritime partner to reduce emissions in shipping

New collaboration powers Maersk Tanker and Cargill-invested ZeroNorth’s vessel optimisation software with Spire’s data, driving impactful revenue and sustainability decision-making  

Spire Maritime & ZeroNorth partner to provide easy access to market-leading AIS and weather forecast data

ZeroNorth Optimise users now get access to clean data to minimise risk and maximise profits 

Spire Maritime provides clean, smart data and solutions delivered through easy-to-use APIs, and we are excited to announce our partnership with ZeroNorth, a maritime tech company that drives data into actions. This partnership allows ZeroNorth’s to leverage comprehensive AIS data and weather forecasts to deliver more accurate actionable data allowing their Optimise platform users to improve their vessel performance, mitigate risk, safeguard cargo, and improve fleet sustainability. 

With the industry’s growing focus on fuel efficiency, emissions reduction, safety and productivity,

it is more important than ever to have access to accurate and comprehensive AIS and weather forecast data. Spire Maritime’s unique combination of Satellite AIS, Dynamic AIS™, and Terrestrial AIS provides users with an unprecedented level of coverage on global maritime shipping routes. This comprehensive tracking data, combined with advanced maritime weather forecasts, provides customers with incredibly comprehensive data that is decluttered, smart, and easy-to-use.

The Spire Maritime Data Difference: Accurate data builds better algorithms 

Spire Maritime’s market-leading AIS data is beyond comprehensive as it combines three types of AIS data - satellite, terrestrial, and our own Dynamic AIS™. 

Dynamic AIS™ is a world-first innovation developed by Spire Maritime to solve the maritime industry’s growing data gap problem. Launched in 2020, Dynamic AIS™ quickly became the new industry standard for global vessel tracking. Dynamic AIS™ delivers unprecedented data in the busiest shipping lanes and congested ports with no AIS data gaps. AIS data gaps in high traffic zones ( ex: South China Sea) have been a challenge in the maritime industry for decades. These gaps impact ship safety, trading, revenue, and insurance claims. Dynamic AIS™ solves the growing data gap problem.


Unprecedented level of coverage

Spire Maritime’s unique combination of Satellite AIS, Dynamic AIS™, and Terrestrial AIS provides users with an unprecedented level of coverage on global maritime shipping routes.

Weather forecast data is essential to building optimised operations especially in maritime where the weather creates delays, impacts crew assignments and routing, and affects fuel efficiency. Collecting weather data in remote areas and open oceans is challenging. This partnership with  Spire Maritime includes Spire Weather’s Maritime Weather API. 

Using Weather forecasts for increased Vessel Performance 

Spire’s proprietary radio occultation data provides global coverage and high resolution in open oceans. Radio occultation measures how GPS signals bend as they pass through the atmosphere between satellites. This measurement reveals the temperature, pressure, and humidity in the atmosphere. As satellites continue to orbit and relay signals, Spire Weather captures a detailed vertical profile of the atmosphere and homogeneously collected across the entire globe - providing a unique coverage.

Radio occultation captures detailed temperature, humidity, and pressure information across the entire planet, including our vast oceans and under-observed areas. The resulting boost to weather prediction is beneficial to global maritime enterprises as well as many other industries. Ocean weather conditions have a direct impact on shipping costs, cargo protection, time estimating, and fuel efficiency. The more data seafarers have on waves, wind and currents the better they can navigate to optimise fuel efficiency and plan more accurate arrival times.

How it works

Spire collects data with its constellation of Low Earth Multi-Use Receiver (LEMUR) a 3U CubeSat platform able to track maritime, aviation, and weather activity from space.

Spire Satellite AIS data and Radio Occultation is captured from space using it’s own network of ground stations where it is cleaned and refined and delivered into easy-to-use REST APIs. 

Spire’s Maritime and Maritime Weather API provides clean and smart data directly to Optimise platform. Using this same data, operators receive action-led recommendations to improve their time charter equivalent rate (TCE) while simultaneously lowering CO2 emissions. 


-  The Low Earth Multi-Use Receiver (LEMUR) is Spire’s 3U CubeSat platform used to track maritime, aviation, and weather activity from space

-   Spire operates the world’s largest RF sensing fleet and are the largest producer of radio occultation and space weather data

-   Spire’s data provides a global view with coverage in remote regions like oceans and poles not observed by traditional systems.

-   All data can be refreshed within a 15 minutes cycle

-   Spire continuously launches improved sensors and upgrades them in-orbit.
