With their maiden orbital docking mission aimed for 2027, Aule Space is likely to become the 2nd company in the world to perform a 100% optical camera aided docking!
While other spacecrafts (including ISRO's SpaDEx) uses expensive LiDAR & Laser Range Finder tech for determining the relative distance and orientation of the target spacecraft which they want to dock to, Aule Space's entirely camera-based computer vision architecture makes their system highly cost effective. They plan to use this system on their 'jetpack' satellites which are essentially mission extension vehicles designed to service and extend the service life of satellites (especially in Geostationary Orbit) that are fully functional but have run out of propellants, by docking with them and acting as a jetpack, even if those satellites were never originally designed to be docked to.
As Aule Space is among the first to attempt docking like this using only cameras, there is a lack of a sufficiently large image dataset containing close-up images of satellites in orbit to train their computer vision model on.
To tackle this, Aule Space set up their own dark room facility, used a light source to simulate the Sun, and moved a dummy satellite using robotic arms to simulate how satellites would appear and move in the darkness of space partially illuminated by sunlight to train their model.
Then using this model, they succesfully tested the final 15 meters of autonomous proximity operations at ISRO's Rendezvous Simulation Lab (where SpaDEx was tested) at ISITE in UR Rao Satellite Centre (URSC)! With this, their system achieved a technology readiness level of TRL-6!
Aule Space builds the robotic workforce for satellites in orbit, pioneering autonomous RPOD and satellite-agnostic docking where intelligence meets universal compatibility, saving billions in space infrastructure.

My comments:
There's been an absolute explosion of private spacetech firms. It's almost impossible to keep track of what everyone's doing! That said, what Aule Space is working on is essentially the equivalent of Northrop's Mission Extension Pod (MEP) tech.
The big difference seems to be that Northrop's solution requires a larger Mission Robotic Vehicle (MRV) with arms to manually place the 'jetpack' onto the client satellite, whereas what Aule is developing has the jetpack satellite guide itself into position using computer vision. A far more efficient & less expensive way to get it done if they can demonstrate it.
