卫星资料:
NAME: AO-27/AMRAD
LAUNCHED: 1993/09/26
SITE: Kourou, French Guiana
STATUS: Semi-operational, mode J
DNLINK: 436.795 FM Voice
UPLINK: 145.850 FM
NOTES: AO-27's orbit has moved the satellite into a period of Full Orbit Solar Illumination. Due to this, the TEPR method of timing the Transmitter does not work. Therefore AO-27 cannot turn its transmitter on by itself and can only be turned on by ground station command.
在这个位置,根据跟踪软件的多普勒频率,听到有1个QSO,语音只有2分

这次因为卫星抵达上海附近与天线有一定的夹角,所以信号始终连续无终端

上次在大溪地听南方(长江以南)的微弱信号是怎么实线的?

QUOTE:
原则上因为地表曲线原因,超过200公里后U/V的传播使命就此结束但因为各种气侯的原因,一旦U/V传播打开,往往很小的功率信号就传上百上千公里
U/V在上海这里往北传播好的时候最远能到青岛(直线距离400多公里,信号直接海面传播)
泰山中继目前还无法打开
