PRETS 300 721-1996 Satellite Earth Stations and Systems (SES); Mobile Earth Stations MESs) Providing Low Bit Rate Data Communications (LBRDC) Using Satellites in Low Earth Orbits (LEO) and Operating in Frequency Bands Below 1 GHz
This European Telecommunication Standard (ETS) provides specifications for the standardization of the characteristics of Mobile Earth Stations (MESs) with both transmit and receive capabilities in order to limit interference to radiocommunications services. The Low Earth Orbiting (LEO) satellite networks referred to in this ETS operate under the Mobile Satellite Service (MSS). The MESs operate as part of a LEO satellite network providing Low Bit Rate Data Communications (LBRDC). These MESs generally have the following characteristics: - the MESs could be eitherVehicle mountedor Portable equipment; - the MES could consist of a number of modules including suitable interfaces to the user. The main specifications are contained in two categories related to: - unwanted emissions limitation: to protect terrestrial and space radiocommunications services@ and the radio astronomy services from harmful interference; - MES control and monitoring functions: to specify a minimum set of Control and Monitoring Functions (CMFs) to be implemented on each MES in order to minimize the probability that they originate unwanted transmissions that may give rise to harmful interference to other systems.
