GPS ( Global Positioning System )

Latest/Current Research and Key developments
In the mobile phone domain, GPS receivers are very much in demand today. In a few years from now, all GSM phones are expected to be fitted with superior GPS technology to help the user in navigation. This superior GPS technology will also help track other GPS-mobile enabled users. For example, anxious parents can keep a tab on the movements of their children. It also helps to keep track of individuals working in high-risk areas.
 
Another important feature is the GPS-enabled theft-protection systems that are very much in demand these days. This helps motorcycle and automobile manufacturers to locate stolen vehicles with pinpoint accuracy.
 
A big boost is provided to computer users in the form of Bluetooth GPS receivers. These receivers score over traditional connections because a cable is not required.
GPS is also being introduced into supply chains, to ensure that all goods are transported without hassles and are free from theft.
 
Problems being faced today
The most common problem that arises with the GPS system is accuracy. Accuracy depends on the signal that is sent by the time unit. The accuracy gets disturbed if the time is off in the GPS unit. The time and calculations are affected when it encounters rough atmospheric conditions. Inaccuracy occurs when a signal is bounced back from mountains, skyscrapers etc.
 
Another problem is related to its position that gets updated every twelve minutes. Once the signal has reached the updated time, the satellite is unable to know the correct location and can make calculation on based on the wrong information. This kind of errors is unavoidable.
