Действует
Satellite Earth Stations and Systems (SES) - Mobile Earth Stations (MES) providing Low Bit Rate Data Communications (LBRDC) using Low Earth Orbiting (LEO) satellites operating below 1 GHz
The present document specifies those technical requirements that apply to Mobile Earth Stations (MESs) for compliance
with article 17 of Council Directive 98/13/EC [1].
There are no essential requirements under article 17.6 of Directive 98/13/EC [1] for terminals approved against the
present document, and there is no guarantee of correct interworking between satellite earth station equipment.
The MESs will operate in frequency range below 1 GHz, in one or more of the Mobile Satellite Service (MSS)/Land
Mobile-Satellite Service (LMSS) frequency bands given in table 1.
- The MESs could be a Based MES (BMES), a Vehicle mounted MES (VMES), or a Portable MES (PME S).
- The MESs operate through satellites in Low Earth Orbit (LEO) as part of a network providing Low Bit Rate Data
Communications (LBRDC).
- The MESs are controlled and monitored by a Network Control Facility (NCF). The NCF is outside the scope of
the present document.
The requirements of the present document shall be selected to ensure an adequate level of compatibility with other radio
services.
The present document does not contain any requirement, recommendation, or information about the installation of the
MESs.
Compliance of MESs to the requirements of the present document does not imply that the MESs may be used. In
conformity with article 15.2 of Directive 98/13/EC [1] the use of such equipment may be subject to licensing terms in
conformity with Community law.
