There is little potential of action in case of conjunctions where neither chaser nor target can be controlled by spacecraft operators. Nevertheless, potential collisions between such objects pose a significant threat to the space environment. In view of that, some recent studies and developments addressed the concept of momentum transfer (MT) from ground-based lasers for orbit modification and, therefore, collision avoidance. However, achievable delta-v increments are highly constrained (pass geometry) and uncertain (tracking accuracy, atmospheric turbulence, object properties). Therefore, we present and study a probabilistic model for MT-based collision avoidance. We derive requirements on laser power, MT success rate, and orbit prediction uncertainty as a function of turbulence compensation capability, time to event, conjunction angle, and area-to-mass ratio. Our results demonstrate capabilities and limitations of the method given currently available technology.
