The present document applies to Mobile Earth Station (MES) radio equipment which have the following characteristics:
• these MES operate in a non-geostationary orbit (NGSO) mobile-satellite system;
• these MES have both transmit and receive capabilities and operate in a Satellite-Personal Communications
Network (S-PCN). An S-PCN MES may be handheld, portable, vehicle-mounted, host connected, semi-fixed
or fixed equipment, or may be an element in a multi-mode terminal. It may consist of a number of modules
with associated connections and user interface, or may be a self-contained single unit;
• these LMESs are controlled and monitored by a Network Control Facility (NCF). The NCF is outside the
scope of the present document;
• if the MES is an element in a multi-mode terminal, unless otherwise stated in the present document, its
requirements apply only to the S-PCN MES element of the terminal operating in the MSS frequency bands
given in table 1;
• these MES are capable in operating in all or part of the frequency bands shown in table 1.
Table 1: Mobile Satellite Service (MSS) frequency bands
MES MSS frequency bands
Transmit (earth to space) 1 980 MHz to 2 010 MHz
Receive (space to earth) 2 170 MHz to 2 200 MHz
The present document is intended to cover the provisions of Directive 2014/53/EU [7] (RE Directive) article 3.2 which
states that "….radio equipment shall be so constructed that it both effectively uses and supports the efficient use of
radio spectrum in order to avoid harmful interference".
In addition to the present document, other ENs that specify technical requirements in respect of essential requirements
under other parts of article 3 of the Directive 2014/53/EU [7] may apply to equipment within the scope of the present
document.
NOTE: A list of such ENs is included on the ETSI web site.
