to a couple of their colleagues who had other kind of specialties. And they said, “Jeez, you know, we think we could actually figure out the points at which the satellite is closest to our antennae18) and the points at which it’s farthest away. ” At the end of about three or four weeks, it turns out they have mapped the exact trajectory19) of this satellite around the Earth.
他俩坐在那儿聚精会神地听信号,其他人纷纷涌进办公室,说道:“哇,这太厉害了。能让我听一下吗?”很快,他们意识到:“天哪,这可是历史性的一刻啊!我们也许是全美国最先听到这个信号的人。我们应该把它录下来!”于是,他们就搬来一台庞大笨重的模拟磁带录音机,开始录下这些微弱的哔哔声,还为录下的每一个哔哔声记下了日期和时间。接着他们又想:“天哪,我们注意到了细微的频率变化,没准儿可以计算出卫星运行的速度呢!”于是他们进行了反复的计算和论证,还和几个有其他专长的同事讨论了一番。然后他们惊叹道:“呀!知道吗,我们相信我们真能计算出卫星距离我们的天线最近和最远的点。”大约三四周之后,他们果真绘制出了这颗卫星绕地球运行的精确轨道图。
