How It Works

Our innovative technology turns single capability satellites into multi-use capability satellites to make the most of their time in orbit without compromising core mission objectives. Our approach involves completing requests based on another passing satellite rather than relying on a prime location on Earth. We take care of the entire imaging process and all you need to do is point and image.​​

We developed two telescopic space cameras, Holmes and Adler, designed to be easily hosted as a secondary payload on spacecraft.

We give you absolute control

Our program has been designed to compliment Earth Observation, Space Logistics and In-Space Servicing applications. We'll use your sensor during downtime and take care of the entire imaging process.

Focus On Your Mission

Our technology integrates with your existing systems without compromising core mission objectives


Holmes is the world’s first commercial camera dedicated to non-Earth imaging. It is HEO’s first in-orbit imaging system designed and developed to deliver the highest resolution in a compact form on micro-sized satellites. Operating as a hosted payload, Holmes is able to capture resolved imagery of space objects as they fly past the host spacecraft.

Adler is HEO’s second in-orbit imaging system engineered for exceptional spatial resolution on small to large-sized satellites. Operating as a hosted payload, Adler is Australia’s largest space telescope and is optimised to achieve higher resolutions at a much larger frame rate.
