Guardian is a prototype for 6U CubeSat developed by Aistech to provide thermal images of the Earth. Aistech is planning to deploy a constellation of 20 thermal-enabled satellites.

The nanosatellite, named Guardian, carries a multispectral telescope designed by Aistech Space, with a variety of sensors from the visible (RGB), near infrared (NIR), and thermal infrared (TIR) spectrum. The satellite is built by OrbAstro.

Guardian will be launched and deployed with the ION-SCV 004 orbital transportation vehicle designed, manufactured, and operated by D-Orbit to transport a batch of satellites into space, perform orbital manoeuvres, and deploy them with precision into their operational orbits. Guardian will be integrated inside ION’s dispensers, alongside other spacecraft, and deployed according to Aistech Space’s requirements.
