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 will demonstrate world first massive IoT satellite services and will deliver 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 performances are the key targets of 6G NTN, achieved already today with Golden Modulation from TERNWAVES with Eutelsat LEO satellites and the support of ESA.
Users and their needs
These IoT services are for worldwide actors in verticals such as logistics, transport, agriculture/smart farming, maritime, environmental, mining/oil/gas, smart cities, smart building, e-health, utilities, industry… who need IoT connectivity.
TEMIS demonstration will involve users from Logistics, Mobility, Disaster management and Seismic & infrastructures monitoring verticals.
These users need:
-
Global coverage that can be achieved only with satellites network
-
Capacity to support:
-
high density area such as high traffic roads, freight port,
-
peak load in case of disaster
-
scalability
-
-
True resilience in case of GNSS denied environment or jamming.
-
Low power consumption of high battery life time of the connected devices
-
Low cost services
Service/ system concept
The system and service architecture is schematised below.
TERNWAVES:
-
brings the IoT connectivity technology called Golden Modulation and the geolocation technology based on the Golden Modulation to be ported as a software on Eutelsat LEO satellite Software Defined Radio (SDR) payload.
-
develops the connected devices for the various verticals with Golden Modulation embedded.
-
develops the dashboards for the users of the different verticals
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 the IoT connectivity technology called Golden Modulation 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, 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 thanks to Golden Modulation as it is an asynchronous technology fully operational even in GNSS denied environment or in case of jamming.
For this demonstration, Eutelsat LEO satellites and ground stations are used.
Current Status
The service specifications for the 4 verticals (Logistics, Mobility, Disaster management and Seismic & infrastructures monitoring) have been completed.
User terminal release 1, using Commercial Off The Shelf (COTS) components, is in manufacturing phase.
Overall IT infrastructure for protocol updates development has been defined and deployed, including hardware selection, IT architecture and tools selection.
Integration of satellite gateway is in finalization phase.
Ground segment adaptation and integration is in progress.
