Objectives of the service

Current IoT and more broadly D2D satellite connectivity technologies are facing 2 major limitations:

  • a capacity limitation. It has a twofold impact:

    • Current IoT satellite connectivity technologies cannot support high-density areas, such as high traffic roads, freight port, peak load in case of disaster, …

    • No scalability for massive users’ adoption and for a lot of new different verticals & applications

  • Non-resilience in case of GNSS denied and/or jamming.

TEMIS project has demonstrated world first massive IoT satellite services and has delivered the first end-to-end commercial ready spatial IoT services with proven massive capacity, while being fully operational in GNSS-denied environment and very robust to jamming and interferences.

These unique performances have been achieved with Golden Modulation™ technology from TERNWAVES with Eutelsat LEO satellites and the support of ESA.

Connectivity resilience for devices on-the-move in GNSS-denied environment is no more a nice to have in Europe.

Users and their needs

TEMIS IoT connectivity services are scalable to worldwide actors in multiple verticals such as logistics, transport, agriculture/smart farming, maritime, environmental, mining/oil/gas, smart cities, smart building, e-health, utilities, industry… 

These users need:

  • Global coverage achievable only through satellites network

  • Capacity to support:

    • high density area such as high traffic roads, freight port, 

    • peak load in case of disaster

    • scalability while not compromising reliability

  • True resilience, even in GNSS-denied or jammed environments

  • Low power consumption for maximum autonomy of the connected devices

  • Low cost services

TEMIS IoT end-to-end connectivity services have been demonstrated for “24/7, real time” monitoring of urban heat islands (UHIs) with 3ZA company for the Centre-Val de Loire Region and Orléans Metropolitan Authority in France.

With climate change driving hotter summers, cities face growing public health risks, particularly for children, the elderly, and vulnerable populations. 

Deploying large numbers of sensors is essential for authorities to identify the areas most affected by overheating, monitor changes in real time, and better understand how urban design, vegetation, and local climate factors interact. This data is crucial to creating strategies and tools to build more resilient, inclusive and livable cities.

Service/ system concept

The system and service architecture are schematised below.

 TERNWAVES:

  • Delivers Golden Modulation™ software to be ported on Eutelsat LEO satellite Software Defined Radio (SDR) based payload already in orbit via OTA;

  • Delivers protocols and servers for ground segment;

  • Develops & delivers the connected devices with Golden Modulation embedded upon customers’ requirements;

  • Develops & delivers the dashboards for the different verticals upon customers’ requirements;

  • Operates the IoT end-to-end connectivity services for customers which have direct access to the services via the respective customized dashboard (accessible via smartphones, tablets, PCs)

Eutelsat:

  • Makes available the flexible SDR payload on board of its LEO spacecraft in order to host the IoT connectivity technology called Golden Modulation™;

  • Supports the software porting activities of Golden Modulation™ modem on the flexible SDR payload available on board of its LEO spacecraft;

  • Controls and configures the flexible SDR payload in order to grant a reliable quality of service during the demo phase with verticals.

Space Added Value

The very first need of users is to get a global coverage, especially useful for applications in logistics, environment or disaster management, agriculture, maritime and intermodal transportation, oil and gas industry exploration, utilities, construction and governments. But only about 10 percent of the Earth’s surface has access to terrestrial connectivity services. Therefore, satellites network is THE solution for ubiquitous connectivity services. 

Moreover, in case of disaster, terrestrial network can be out of order. Satellites network brings the first level of resilience in such a case. 
Further resilience is achieved with TEMIS services thanks to Golden Modulation™ connectivity technology as it is an asynchronous technology fully operational even in GNSS-denied or jammed environment.

For this demonstration, Eutelsat LEO satellites and ground stations have been used. 
 

Current Status

The pilot services deployed through TEMIS project successfully met all the objectives set by 3ZA partner for its mission to monitor “24/7, real time” urban heat islands (UHIs) for the Centre-Val de Loire Region and Orléans Metropolitan Authority in France.

  • Spatiotemporal environmental data were successfully collected during a heatwave episode.

  • The real-time availability of measurements enabled researchers to finalize models for converting surface temperatures into air temperatures, while also allowing for the immediate identification of priority study areas.

  • The calculation of the humidex index for schoolyards under different conditions (high/low sunshine, rainfall events, wind gusts, etc.) will allow the Metropolitan Heritage Services to prioritize OASIS (2) redevelopment projects.

These IoT end-to-end connectivity services are ready to be deployed on any LEO satellite’s constellations from any operators (beyond Eutelsat ones), as long as the satellite onboard communication payload is based on programmable software-defined radio (SDR) hardware, and for multiple verticals (Logistics & Transport, Automotive market, Disaster Management, Seismic & infrastructures monitoring market and 24/7, real time environment monitoring, but also agriculture/smart farming, maritime, environmental, mining/oil/gas, smart cities, smart building, e-health, utilities, industry…).
