用于预测气象卫星轨迹及收集其扫描地球产生的图像。[img]http://www.david-taylor.pwp.blueyonder.co.uk/software/wxtrack-at-work-sm.jpg[/img]Multiple satellite tracking, with night-time shading.This program, which I have described in more detail, is designed to predict the tracks of satellites both as paths above the earth, and as images produced by these satellites when scanning the ground. It was designed for use during the early stages of my weather satellite receiving activities, when clouds and interference prevented easy identification of what I was actually observing!
