The present document applies to Mobile Earth Stations (MES) providing Low Bit Rate Data Communications (LBRDC) using Low Earth Orbiting (LEO) satellites and which have the following characteristics:

• - the MES could be a Based MES (BMES), a Vehicle mounted MES (VMES), or a Portable MES (PMES);
• - the MESs operate through satellites in Low Earth Orbit (LEO) as part of a network providing Low Bit Rate Data Communications (LBRDC);-

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 effi-cient 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 re-quirements under other parts of article 3 of the RE Directive [7] may apply to equipment within the scope of the present document.
