WT——1A 型卫星云图接收系统,是用来接收美国第三代极轨气象卫星播发的云图讯号。121传真机是这套系统的终端设备。出于这套设备较之以往使用过的118传真机要复杂一些,因此,在现有的条件下,如何才能使用好该设备,将它调整到比较理想的状态,充分发挥其性能,是一个值得探讨的问题。本文要讲的是同步装置内主扫描系统的
The WT - 1A satellite cloud image receiving system is used to receive cloud images broadcast by the third generation of polar orbiting weather satellites in the United States. The fax machine is the terminal of this system. For this set of equipment than the 118 fax machines used in the past to be more complex, so under the existing conditions, how to use the device, adjust it to an ideal state, give full play to its performance, is a Worth to explore the issue. This article is about the main scanning system within the synchronization unit
