How GPS Satellites Calculate Your Spot
The US military forces launched the first GPS satellite in 1978. Since then, more then three dozens satellites have been launched on Earth’s orbit, servicing not only military and aviation forces but individual private users worldwide. The very existence of the Global Positioning System has in fact claimed the life of more than one GPS satellite, lost during the launch or on the orbit. Some satellites expired, others were replaced, but but no effort was spared for making GPS usage top quality. 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 seem to act against the proper reconditioning of the Global Positioning System. The US Air Force maintains the entire GPS satellite structure, but according to a recent May 2009 report, there are economic difficulties to be overcome.
At present there are some 31 satellites in service and since only four are necessary to get a fix on the position, the average user will not feel a change if some of the orbiting devices fail to work. There is a certain redundancy in the way information is provided, because sometimes, the same GPS receiver can get simultaneous data from six or eight satellites, which is more than necessary. 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 suffer most if the satellites are not reconditioned.
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 managed in terms of administration, implementation and foreign policy at the global level, the average user should not be seriously troubled by the different modifications that may occur in the GPS satellite system. In fact, the number of GPS users will get higher because of people’s attempt to improve the efficiency of navigation.

Future Prospects For GPS Sales
According to tech trends forecasters and in reference to the economic projections for 2009, GPS sales are believed to enter a flat evolution rate for the coming period. The entire electronics sectors has been affected by the financial crisis, yet, GPS sales are still positive, although not ascending, given the consumer’s lower purchase capacity. It seems that the preference goes for the touchscreen GPS smartphones, ambitious products that have changed the technological face of communications. The rest of the personal navigation devices will remain moderate in demand, and manufacturers are lucky that the GPS sales continue to be profitable.
People continue to buy GPS devices, because until very recently, only a limited number of users had such systems installed in the personal car. The difficulty to go through crowded city traffic, the need to save time and stay relaxed when going on vacation by car, the sheer pleasure of having a high-tech device on the dashboard, these could be enough reasons to justify the level of GPS sales. Many users are attracted by items that are both money wise and innovative, and manufacturing companies can no longer afford to set too high prices for their models for fear of discouraging GPS sales and risking financial loss.
The quality of personal navigation definitely improves thanks to the implementation of the GPS technology. Studies show that people who use the Geographic Positioning System enjoy lower fuel consume, have a higher efficiency rate and are less tired by driving. The GPS sales now explain the decrease of the distances driven per year and lead to considerable annual savings. The ultimate device for traffic detection and quality routine or non-routine trips is the GPS with traffic detection: use it and you will see the difference. Furthermore, you won’t spend that much time checking maps and preparing the travel details for a longer journey.
All in all, on the background of positive statistics, GPS sales should be encouraged, and with every year the number of the GPS system users will be higher. The best GPS sales are usually reported for brand manufacturers such as Garmin, TomTom, Mio or Magellan, but there are smaller companies that are competitive on the market because of their low price policies. For anyone inclined to buy a cheaper device, make sure to check all the features and get aware of the provided quality level. A comparison between different models should reveal a lot.
