“…Most of the current dedicated optical ground stations are concentrated in the mid latitudes of the northern hemisphere. Examples of the distribution of such networks are given by the International Scientific Optical Network (ISON) [12], for the passive electro-optical case, and by the International Laser Ranging Service (ILRS) [13] for the active electro-optical; note that from the ILRS, only selected stations are able to observe either cooperative RSOs during daylight, or noncooperative RSOs with high power dedicated defunct RSO lasers. Even though there are recent developments of tracking networks with a better geographical distribution, such as the Small Aperture Robotic Telescope Network (SMARTnet) [14], the productivity of such observing networks is restricted mainly to night observation sessions.…”
