It operates using a ground control station and satellite equipment.

它使用地面控制站和卫星设备运行。

I am particularly interested in TV broadcasting from satellites directly into the home, bypassing today's ground stations, a proposal I first described 22 years ago.

我对从卫星直接进入家庭的电视广播特别感兴趣，绕过今天的地面站， 这是我 22 年前首次提出的建议。

Direct broadcast TV will be possible within 5 years and may be most important to undeveloped countries that have no ground stations, and now may never require any.

直播电视将在 5 年内成为可能，对于没有地面站的不发达国家来说可能是最重要的，现在可能永远不需要地面站。
