本TBR规定了理事会指令93/97/EEC第4.1至4.5条中适用于卫星地面站设备的技术要求，这些设备能够在以下一个或多个频率范围内运行:-1 530,0至1 533,0 MHz和1 555,0至1 559,0 MHz（空间-地球）；-1626.5至1645.5兆赫和1656.5至1660.5兆赫（地对空）；移动卫星服务（MSS）。这些要求摘自ETS 300 423。本TBR不包含第4.6条关于在合理情况下通过公共电信网络互通的基本要求，也不提供卫星地面站设备之间正确互通的任何保证。本TBR规定了卫星地面站设备的要求:-能够仅用于传输、传输和接收（发送-接收）或仅用于接收（接收）上述任何频带中的无线电通信信号，以及- 不打算用作公共电信网络的一部分。本TBR适用于上述所有卫星设备，无论卫星地面站设备是否提供额外的接口、电信服务或功能。然而，其他TBR也可能适用。

This TBR specifies those technical requirements under Articles 4.1 to 4.5 of Council Directive 93/97/EEC that apply to satellite earth station equipment that is capable of operation in one or more of the following frequency ranges: - 1 530,0 to 1 533,0 MHz and 1 555,0 to 1 559,0 MHz (Space - Earth); - 1 626,5 to 1 645,5 MHz and 1 656,5 to 1 660,5 MHz (Earth to Space); of the Mobile Satellite Service (MSS). These requirements are taken from ETS 300 423. This TBR does not contain the essential requirements under Article 4.6 for interworking via the public telecommunications network in justified cases, and does not provide any guarantee of correct interworking between satellite earth station equipment. This TBR specifies the requirements for satellite earth station equipment that: - is capable of being used either for transmission only, or for transmission and reception (transmit-receive), or for reception only (receive-only), of radio-communications signals in any of the bands specified above, and - is not intended for use as part of the public telecommunications network. This TBR applies to all satellite equipment as described above, irrespective of whether the satellite earth station equipment provides additional interfaces, telecommunications services or functions. However additional TBRs may also apply.
