Air-to-Ground Terminals

High-speed ground connectivity for aircraft, UAVs, high altitude platforms (HAPs) and more...

Micro Laser Terminals

ViaLight’s Micro Laser Terminals for Air-To-Ground links (MLT-ATG) allow free space optic (FSO) communication between airborne objects and the ground. The compact systems are based on an innovative pointing mechanism, low power consumption and heat dissipation and are optimized for the dynamic behavior of high altitude platforms as well as for the regular airspace. The MLT-ATG terminals are typically used in combination with one of our optical ground stations to establish an air-to-ground link.

  • Range: up to 200km link distance
  • Data rate: up to 10 Gbps
  • Safe technology: only minimal precautions necessary
  • Made for air: resistant to temperature and vibrations
  • Payload: small size, low weight and power consumption (SWaP)
  • Regulation: none, no ITU license required
  • Privacy: resistant to tapping, jamming or spoofing

Link Scenarios

ViaLight’s Air-to-Ground terminals are designed to enable high-speed communication links between high flying objects or regular aircraft to one of our optical ground stations. Depending on the specific terminal they allow to establish a high-speed connection to the ground for aerostatic or low/medium-velocity aerodynamic platforms such as stratospheric balloons or other high-altitude platforms (HAPs) in the stratosphere or for airborne objects in the regular airspace with high velocities and strong vibrations.
