A system to distribute synchronization signals via geostationary satellite has been developed. This system uses a satellite in geostationary orbit without the need for dedicated bandwidth. A prototype has been developed using SDR-technique to validate part of the system. Preliminary measurements were carried out at Telespazio Fucino Space Centre through the Eutelsat 33E satellite. Results show a wander no larger than 100ns peak-to-peak.

地球静止卫星时间和频率传播系统：初步实验

已经开发了一种通过地球同步卫星分配同步信号的系统。该系统使用地球静止轨道上的卫星，无需专用带宽。使用 SDR 技术开发了一个原型来验证系统的一部分。通过 Eutelsat 33E 卫星在 Telespazio Fucino 航天中心进行了初步测量。结果显示峰峰值漂移不超过 100ns。
