The present document applies to Earth Stations on Mobile Platforms (ESOMP), which have the following characteristics. Figure 1: ESOMP System Overview • The ESOMP is designed for both mobile and stationary operation. • The ESOMP operates on various mobile platforms such as trains, maritime vessels, aircraft and other vehicles and, therefore, may be subject to occasional disturbances and interruptions in the satellite link. • The ESOMP is operating as part of a satellite network (e.g. star, mesh or point-to-point) used for the distribution and/or exchange of information. • The ESOMP is comprised of all the equipment, electrical and mechanical, from the antenna itself to the interface with other communications equipment on a mobile platform (usually referred to as the terrestrial interface). • The transmit and receive frequencies are shown in table 1. Table 1: Frequency bands Frequency Bands/frequencies (GHz) Transmit (Earth-to-space) 27,50 to 30,00 Receive (space-to-Earth) 17,30 to 20,20 • The ESOMP transmits within the frequency range from 27,50 GHz to 30,00 GHz, which is a band allocated to the Fixed Satellite Services (FSS) (Earth-to-space) among other services. However, operation of the ESOMP is intended to be restricted to the frequency range 29,50 GHz to 30,00 GHz in and near those countries that have allocated Fixed Service (FS) to the other frequency ranges. Local regulation may permit operation in these frequency ranges. • The ESOMP receives in one or more frequencies within the range from 17,30 GHz to 20,20 GHz (FSS). • The ESOMP uses linear or circular polarization. • The ESOMP operates through a geostationary satellite (or a cluster of co-located geostationary satellites) that is at least 2° away from any other geostationary satellite operating in the same frequencies and over the same coverage area. NOTE 1: ESOMPs may operate with satellites that are more closely spaced than 2° with additional operational
