Space-Terrestrial Integrated IoT
Pioneering global connectivity by integrating terrestrial IoT with satellite networks for seamless, energy-efficient, low-data-rate communication anywhere on Earth.
Pioneering global connectivity by integrating terrestrial IoT with satellite networks for seamless, energy-efficient, low-data-rate communication anywhere on Earth.
The STEREO project envisions a future where Internet of Things (IoT) devices are no longer bound to terrestrial infrastructure. By integrating low-power IoT technologies such as LoRaWAN and NB-IoT with Low-Earth Orbit (LEO) satellite gateways, STEREO pioneers a hybrid space-terrestrial network architecture.
This 4-year academic project, led by Inria and supported by a consortium of top academic and industrial partners, breaks new ground in network architectures, protocol design, and real-world validation for Direct-to-Satellite IoT (DtS-IoT) services.
Unmodified devices can connect to terrestrial gateways or directly to LEO satellites.
Low-data rate applications include environmental monitoring, asset tracking, and remote sensing.
Combines simulation, hardware prototyping, and in-orbit protocol validation.
Favors sparse constellations and latency-tolerant protocols to minimize costs and complexity.
Each work package tackles a critical layer of the space-terrestrial integrated IoT stack
Oversees coordination, partner communication, progress tracking, and public outreach.
Designs the end-to-end system architecture combining LPWAN and Argos technologies.
Evaluates physical, link, and network layer performance via simulation.
Develops key software modules including synchronization and constellation management.
Builds and tests hybrid radio components integrating LoRaWAN and Kinéis protocols.
Validates the system via lab testbeds, balloon flights, and in-orbit experiments.
The STEREO project brings together a multidisciplinary team of researchers and engineers from leading French academic institutions and industries working on cutting-edge IoT and satellite technologies.
