Velaris will enable UAVs to fly beyond visual line of sight (BVLOS) and integrate with aircraft in commercial airspace.
The company also said Velaris allows a single pilot to remotely operate multiple UAVs at scale.
Anthony Spouncer, Inmarsat's Senior Director of UAVs and Unmanned Traffic Management, said: "Commercial UAVs have the potential to revolutionise a vast array of different industries throughout the world. However, to truly unlock their potential on a commercial scale, it is imperative that autonomous vehicles and unmanned aviation are safely and securely integrated into managed commercial airspace."
