Sateliot has successfully launched an additional four satellites as part of its 5G NB-IoT NTN constellation.

The company, which is developing a low-Earth orbit (LEO) nanosatellite constellation for IoT connectivity, stated that the launch, deployed on the SpaceX Transporter-11 mission, took place on August 16 aboard a Falcon 9 rocket from Vandenberg Air Force Base in California, USA.

The additional satellites come as Sateliot prepares for its commercial launch.

"This launch propels us into a new phase of development," said Jaume Sanpera, CEO and co-founder of Sateliot. "Not only will we begin generating revenue, but we will also position Spain as a global leader in IoT connectivity."

Sateliot plans to have a constellation of over 100 satellites by 2028, bringing connectivity across the globe.

The constellation is based on the 5G standard which will allow unmodified commercial cellular NB-IoT NTN devices to connect from space. The company claims it is the first such constellation where terrestrial cellular telecommunications seamlessly merge with satellite connectivity

The company has more launches scheduled by 2025, and is reportedly in discussions to secure a Series B funding round of €30 million ($33.15m). The company has raised €25m ($27.63m) since its founding in 2018, and aims to achieve revenues of €1 billion ($1.11bn) by 2030.

The company will initially be connecting its satellites to more than eight million devices that have already contracted the service.

Sateliot launched its first satellite in April 2023, following three unsuccessful launches due to weather conditions. That same month, the company outlined its plans to tap into the US IoT market, filing an application with the Federal Communications Commission (FCC).

That filing was "streamlined" and would allow the company to launch up to 10 satellites, and then add more. At the time, Sanpera said: "This is the first step before we're going to present a commercial pilot in the next weeks in order to have the full constellation, which will go up to 100 satellites. With this filing, we will have full permission to operate inside the United States."
