Conclusion: 3.DEC.2014 Wednesday Information Age-London Trip

This is our world, a photograph taken from a satellite. Somewhere on this indistinct circle there are over three thousand million people who are working, playing, sleeping or – watching this picture.

We have a museum trip in London this week, and visit an amazing exhibition–Information Age in the Science Museum. A really amazed thing for me, is the satellite part of exhibition. As the images illustrate on the below, it present the minimum distance (Image 1) and maximum distance (Image 2) from the satellite to the receiver.

It also explain the methods we located the place with GPS with a interactive screen as image on the below. With two satellite readings (image 3), people could be located in two possible area. If we add one more satellite in the system, it will located more close to the position of the person. With the increasing number of satellite add into the system (image 4), our phones could located more place, and the error will become less.

Therefore, we could see in the image 5 there are plenty of satellites continually transmit signals to Earth, and working together to help users to find the locations.

I think the development of satellite is significant to communication design. As people know, we are living in an digital era. People need to get information accurate and fast, and that exactly how satellite works and helps for our lives. based on the  fast and high effective satellite system, users could connect to someone far away without spend a lot time.
