With the expansion of the Internet of Things (IoT), in sectors as diverse as transport, oil and gas, and agriculture, business-critical information from tens of millions of objects will need to be sent from areas that are not served by terrestrial networks.

Low Earth orbit (LEO) is particularly well-suited to this narrowband connectivity, processing signals emitted by connected objects. It offers a satellite link anywhere in the world, complementing low-power, wide-area wireless technology (LPWA) and 5G NB-IoT terrestrial networks, without increasing the cost or energy consumption of the objects.

With LEO test satellites, called ELO (Eutelsat LEO for Objects), and in cooperation with startups, mobile operators and industries, Eutelsat Group is developing and experimenting the space and ground technologies that will tomorrow provide IoT coverage enabling objects to seamlessly transmit data, irrespective of their location, when they are outside terrestrial coverage.

ELO 1 & ELO 2

The ELO 1 and ELO 2 payloads are hosted on a satellite platform combining several missions. They are being used to support the initial phases of the ELO service.

Satellite manufacturer: Loft Orbital

Size: The host satellite platform measures 70cm x 70cm x 70cm and both ELO 1 and ELO 2’s maximum antenna dimension is 50cm.

Weight: The platform hosting Eutelsat’s payloads weighs 80kg. Both ELO 1 and ELO 2 payloads weigh 8kg.

Coverage: Global

Launch: June 2021

ELO 3 & ELO 4

ELO 3 and ELO 4 will be used to scale up the ELO service.

Satellite manufacturer: Clyde Space

Size: 6U cubesat - 6 litres or 30cm x 20cm x 10cm before the deployment of its solar panels.

Weight: 12 kg.

Coverage: Global

Scheduled launch: ELO 3: Q1/2023 ; ELO 4: Q2/2023
