Addressing astronomical light travel time delays where ground receivers travel tens of kilometers during beam transit.
When sending a laser beam from Mars to Earth, the light takes between 4 and 20 minutes to cross the void. By the time the photons arrive, Earth has moved tens of thousands of kilometers along its orbital path. OISLSpace implements relativistic point-ahead angle solvers that aim the laser at the Earth's future position with sub-micro-radian accuracy.
