==Disposal of GPS satellites==
<b>GPS satellites and the environment</b>
GPS satellites in themselves do not directly affect the environment in a negative manner. However, they do deplete the earth's natural resources on launch. They use us massive amounts of fuel at that time. Once in space, they are however powered by solar energy for sending the signals. They must still have fuel on board for movement however, which kinda sucks. A GPS Satellite has a lifetime of 10 years. Replacements are continously being built and launched into orbit. By 1994, there were 24 GPS satellites

Research questions Environmental factors

Egon:
1. Will LBS have positive impact on the environment, due to less searching time and better location based information. (less use of energy / fuel??)

Reza:
1. How far is the air in major business areas over crowded with the same frequency?

Amarantha:
1. Do satellites affect/change the earth's atmosphere in any way?
2. How are satellites disposed of at the end of their useful life? How long is that life?

Werner:
1. To what extend can the phenomenon of electrical pollution limit the expansion of the use and application of LBS ? ([1])

Research Answers Environmental Factors
