The first GPS satellite was launched in 1978, under the direct command of the US military forces. More than thirty other satellites have been launched ever since for military, aviation and individual usage worldwide. In the history of the Global Positioning System, more than just one GPS satellite has been lost during launches or afterwards. Some satellites expired, others required replacements for technical purposes, but what matters most is how the technology is applied in the performance of daily tasks. A GPS receiver decodes the signal sent by the satellite and gives the exact location based on latitude, longitude and altitude.

Science has made such progress that GPS satellite navigation is now incorporated in the design of smartphones. People depend more and more on GPS orientation and problems may appear if replacements do not come for the orbiting satellites that will expire in a few years. At present, there are funding and management issues that impair the proper reconditioning of the GPS applications. The US Air Force is in charge of the entire GPS satellite structure, but according to a recent May 2009 report, there are economic difficulties to be overcome.

The average user will hardly notice if any of the 31 orbiting satellites will fail, because normally, four satellites at time on the sky are enough to provide adequate information. Sometimes information may get redundant as six up to eight satellites can get connected to a GPS receiver for the same tasks. In the absence of GPS satellite real-time positioning, consumers would have to return to the use of maps all over again. The transportation systems, the maritime and military forces would be the most affected without GPS satellite reconditioning.

The European states are preparing the launch of an independent satellite navigation system in 2010 that would be an alternative to the American GPS satellite applications that are now most popular. There are other countries that have individual satellite navigation and here we can count India, China or Russia. No matter how things are sorted out in terms of administration, implementation and foreign policy at the global level, the average user will not be affected by the different modifications in the way the GPS satellite communication works. More and more people will in fact start using GPS devices for increased efficiency of navigation.
