Notes 5.208A, 5.208B, 5.209
Application S-PCS
Additional information LEO systems. Use is according to RR footnote 5.208 subject to coordination under RR provision 9.11A, RR footnote 5.208A for protection of the radio astronomy service apply, 5.208B apply and the utilisation is in accordance with RR footnote 5.299 limited to non-geostationary-satellite systems. Systems on low-altitude Earth orbits (LEO) in the mobile-satellite service are designated for low capacity data communications M2M, delivery of messages, determination of position and other “non-voice” applications with low duty cycle with worldwide coverage for reception on personal terminals S-PCS.
Future Implementation of low-altitude Earth orbiting systems in the 137–138 MHz band is in Europe harmonised by CEPT Decision CEPT/ErC/DEC/(99)06, which has particularly ensure supervision of these systems development.
