ECSS-E-ST-50-05C (REV. 2), RADIO FREQUENCY AND MODULATION (04-10-2011)

ECSS-E-ST-50-05C (REV. 2), RADIO FREQUENCY AND MODULATION (04-10-2011)., This Standard contains requirements to ensure the following: * Compatibility of frequency usage and modulation schemes between space agenciesʹ spacecraft and Earth stations for the Space Operation, Space Research and Earth Exploration‐Satellite services. * Compatibility between the spacecraft and the networks that they interact with, as far as possible. * Standardization of frequency usage and modulation schemes within the space projects. * Conformity of spacecraft and Earth station parameters to international radio regulatory provisions (Radio Regulations of the International Telecommunication Union (ITU)) and with national regulatory provisions (e.g. national frequency plans). * Selection of the appropriate parameters of spacecraft and Earth stations that are listed in advance of their use, thus enabling coordination with other interested parties. * Optimization of the frequency usage and modulation schemes within the above limitation.
