CalSky

　　CalSky是一个基于网络的用于天文学家观测计划测算的天文计算器工具，由苏伊士大学和欧洲航天局科学助理 Arnold Barmettler
创造，提供英文和德文版，设有日历功能和包括极光信息、彗星、潮汐、太阳能、月食、行星、卫星的位置。

　　网站功能

　　例如使用CalSky来观测“天宫一号”，进入网站后首先设置所在位置，点击右上红框圈来定位，点击地球之后，你会看到这样一个界面，看起来好像很复杂。不过其他的都可以不用管，照图中标示的设置就好了。第一步，在框中填入你所在地区的地名(拼音)，比如我会写“hongkou,
shanghai”;第二步，点击右边的“Start”按钮，此时下面的google地图就会找到你搜索地区的地图，并显示出来;第三步，在地图上找到你所在的位置，双击这里，就会弹出一个气泡框;第四步，点击气泡框里的“Click
here"。接下来，页面会刷新一遍，等待刷新完成，位置已经设置好了。需要你做的，就是把下拉到页面最下方，点击这个红框圈中的“go!”按钮。

　　接着，你就会看到卫星列表啦!现在天宫一号排在最前面，很好找，就是那个“Tiangong-1”!不过，以后它的位置会逐渐排到后面去，因为人类还在不停地发射新的东西，这里你可以设置观测时间，一般会是当前时间，你可以不用去管。下面那条红线标出的，则是你打算让这个网站帮你预报多长的时间段。

CalSky is a web-based astronomical calculator tool for astronomers’ observation programs, developed by Arnold Barmettler, Scientific Assistant of the University of Suez and the European Space Agency

Created, available in English and German, with calendar functions and locations including aurora information, comets, tides, solar energy, eclipses, planets and moons.

Website function

For example, use CalSky to observe “Tiangong 1”. After entering the website, first set the location, click on the red box on the upper right to locate, after clicking on the earth, you will see such an interface, which seems very complicated. But everything else can be ignored, just follow the settings marked in the picture. The first step is to fill in the box with the place name of your area (pinyin), for example, I will write “hongkou”

Step 2, click the “Start” button on the right, and the google map below will find the map of your search area and display it; step 3, find your location on the map, double-click here, and a bubble box will pop up; step 4, click “Click” in the bubble box

Here” . Next, the page will be refreshed, waiting for the refresh to complete, and the location has been set. All you need to do is drop down to the bottom of the page and click “go!” in the red box. Button.

Then you will see the list of satellites! Now Tiangong No. 1 is at the top of the list, and it’s easy to find, that’s the “Tiangong-1”! However, in the future, its position will gradually fall behind, because humans are still constantly launching new things, here you can set the observation time, usually the current time, you don’t have to worry about it. The red line below shows how long you plan to use this site to help you predict.
