Abstract :
A very important class of satellite Earthʹ orbits for the hyge developments of industrial and commercial radiocommunications is the geostationary one. It may be worthy to note that its next decades equivalent in the lunar domain may very well be some of the lagrangian points, which also have interesting astronautical features. Use of Lfar should be strictly forbiden because it would ruin the radio pristine farside. It appears that Lprec would be the most suitable for future lunar telecommunications: it would give access to a whole sector covering one third of the farside, while preserving the pristine radio environment of the remaining 23 farside, including SAHA crater. Thus my proposal is 1) to use the West Third under a regime similar to the International Telecommunication Union one, 2) the Est Third to be left pristine and 3) for the time being, to leave the central far Third in a TBD regime for future discussions. Such a proposal would allow Very Low Frequency (VLF) radioastronomy to settle in the Est Third and Very Long Base Line Interferometry (VLBI) to set, as an extension of the SAHA crater proposal, a triangular network at three choice locations: craters SAHA, TSIOLKOVSKY and MENDELEEV.
