a) My artifact is GPS which is very important to our daily life. There’s many kinds of GPS in the current word, each of them has a different but powerful effect or function. 1..high positioning accuracy： GPS relative positioning accuracy in 50KM up to 10-71000KM up to 10-6100-500KM up to 10-9. In the precise positioning of the 300-1500m engineering, more than 1 hour observation of the solution of the plane the plane position error is less than 1mm. 2.hort observation time： With the continuous improvement of the GPS system, the software is constantly updated, at present, 20KM relative static positioning, only 15-20 minutes, fast and static relative positioning measurement, when each mobile station and the base station is within 15KM, the mobile station observation time just 1-2 minutes, and then can be positioned at any time, every station observation

6.All weather operation： GPS observations can be made at any time within 24 hours of a day, not affected by the weather, cloudy and dark, rain and snow, rain and snow.
b) In the development process I first choose to use internet, because I think there are many useful informations that I can find, and “be familiar with internet” is also a reason for me to use internet. First of all, I went to Wikipedia to find the information I needed, and then he summed it up as a more concise statement. Then I opened the Microsoft Word, divided page into several parts, set up some text books, then wrote the statement in the text box. After that, Adjust the size of the word and the text box, colored the word and text box with the color you like. Finally, added the pictures copied from
