Aéronautics & space
Williamson Electronique is a recognized player in the aerospace and space markets where absolute reliability and safety are imperatives.
Aeronautics
- For many years, WILLIAMSON ELECTRONIQUE has supplied the leading manufacturers of Cospas-Sarsat aviation distress beacons. These beacons locate an aircraft after a crash and must operate for 48 h between –40 °C and +60 °C. For this application, we mainly use Li-MnO₂ and Li-SO₂ technologies.
- We also develop battery packs to provide the necessary power for ground applications (perimeter aircraft protection, runway lighting). These products may use Lithium-ion, Ni-Cd, or Ni-MH technologies.
- We regularly collaborate with aerospace OEMs on specific developments, notably using supercapacitors and Lithium-Ion cells.
Space – Launchers
- We have developed and designed Li-ion battery packs installed on space launchers. These projects tangibly demonstrate our batteries’ high-performance capabilities, withstanding accelerations of several thousands G.
Space – Micro and Nano Satellites
- Williamson Electronique develops packs to operate systems positioned in Earth orbit.
The advantages of our lithium-ion batteries
- High energy density for maximum power and endurance
- Long lifecycle for reliable, long-term operation
- Low weight for improved energy efficiency
- Optimal safety for use in critical environments
