The Internet of ThingsAll of you know that !

Low-Power and Long RangeWAN● LoRa/LoRaWAN● Sigfox● NB-IoT and LTE-M (3GPP)covers most of the (previous) IoT use cases

The Internet of Isolated ThingsIoT networks cover only a few part of the Earthdeserts, oceans, pole regions, unpopulated areasare “not” connected to the global webExamples:

Sat-IoT & LPGAN (i)● Principle
− “Fat” Satellite constellation relays messagesfrom/to alone ground objects.● Satellite-IoT
− Since more than 10 years− Messaging services, Geo-Location services− Terminal drawback : cost, energy, subscription− Operators : Iridium, Eutelsat, Orbcomm, Argos,Inmarsat, Rock7, ...

Sat-IoT & LPGAN (ii)● “New space” & Cubesats− Agile and “affortable” LEO satellites

Interest of cubesats- Component “off the shelf”(Standardized)
- Time developmentreduction
- Cost reduction
Costs: From 500 k€ for 1U to 5 M€ for 1UPossible

Sat-IoT & LPGAN (iii)● LPGAN (Low Power Global Area Networks)
− Goal● Affortable low power terminals● Affortable subscription
− “Affortable” cubesats constellations

LPGAN Players (Large companiesand Startups)● Kinéis (Sigfox+CLS+...)● Lacuna Space● Astrocast● Kepler Communications● KNL Networks● Karten Space● Fleet Space
● Myriota● Hiber● Xingyun● Blink Astro● Analytical Space● Hongyan● ... and many more using(nano)satellites in LEO orbits

The ThingSat projectGoals1) Testing LoRa-based modulation for● ground station ←→ cubesat communications● end-point ←→ cubesat communications2) Testing applications● delay tolerant networks EP ←→ CS ←→ GS● multi-lateration of EP● clock distribution● track and monitor “zombie” satellite
