Abstract: A terminal is configured to communicate with another terminal using an optical link. The terminal includes an optical transmitter configured to emit an optical beam, an optical receiver configured to receive an optical signal, and a computing device configured to control the optical transmitter and to receive the optical signal from the optical receiver. The computing device is configured to establish the optical link with the another terminal by, (1) dividing an area of uncertainty, where the another terminal is located, into one spherical region (1) and an annulus ring (2)−(1), wherein each of (1) and (2) are spherical regions with radii 2>1, (2) scanning first the spherical region (1) with the optical beam, and (3) scanning second the spherical region (1) and the annulus ring (2)−(1) with the optical beam.
