These include an off-line training requirement and relying on the iterative closest point (icp) that does not guarantee a globally optimum solution.
The primary relative navigation sensor of the prisma formation is a gps-based navigation system developed by dlr/gsoc the relative gps serves as both a safe mode sensor of the formation to support failure detection, isolation, and recovery tasks like collision avoidance, and as navigation source for the onboard feedback controllers to enable autonomous formation-flying and rendezvous experiments.

On-orbit service (oos) has demonstrated great potential in future space mission. The target in the oos mission are often noncooperative spacecrafts. The unavailability of the artificial retroflectors and communication link makes it a great challenge to acquire the state of motion of the noncooperative target through relative navigation during the rendzvous in close range.
The task of estimating the motion of one space object relative to another is referred to as relative navigation (relnav). Most commonly, the first object is your spacecraft and the second object is the thing you’re visiting/observing --- such as another spacecraft or an asteroid. As a result, the relnav problem arises in a number of important spaceflight mission scenarios, such as international space station (iss) resupply, satellite servicing, and formation flying.
A new technology called terrain relative navigation (trn) will allow the spacecraft to avoid hazards autonomously. It's the closest thing to having an astronaut piloting the spacecraft, and the technology will benefit future robotic and human exploration of mars.

Abstract: autonomous relative navigation is a critical functionality which needs to be developed to enable safe maneuvers of a servicing spacecraft (chaser) in close-proximity with respect to an uncooperative space target, in the frame of future on-orbit servicing or active debris removal missions. Due to the uncooperative nature of the target, in these scenarios, relative navigation is carried out exploiting active or passive electro-optical sensors mounted on board the chaser.
