Zenno Superconducting Magnetic Torquers Aim to Refine Satellite Positioning 

Superconducting magnetic torquers for high-precision satellite positioning from Zenno Astronautics in Auckland, New Zealand are bringing a new application for high-temperature superconductor tape into the spotlight. The novel devices are attracting innovation funding from Asia-Pacific sources and are set to use HTS tape from Faraday Factory Japan that can conduct electrical currents with zero electrical resistance and an extremely high current density of several hundred amperes per square millimeter.

The company’s Z01 torquer scales to address satellites from 50kg up to space station sized, powering their frequent needs to make spatial adjustments while in orbit. The torquer presents a fuel-free “non-propellant” solution that in 2023 became the first such device to go into space. […]
