      Testing is about to begin on the next-generation of Global Positioning System [GPS] satellites, with the arrival of a prototype unit at a Lockheed Martin complex in Colorado. These "Block III" satellites are part of a $5.5 billion upgrade to GPS, a government-run system that consumers rely on for directions on their phones, cars and standalone navigation devices. But we have to know what this technology provides for normal costumers. So we can get some sub units. 
Brings us More Accuracy. 
   Block III satellites will be capable for determining the position within three feet when compared to 10 feet in current satellite technology. And this accurate positioning will make driving navigation more easy and Help companies like Google for better mapping service. 

Reliable Covering
   This new technology will be better in the places where the current one is facing some problems for covering due to heavy tree canopies or on the city streets which are covered by skyscrapers. And the covered areas will be more sharper in view and reliable. And it will also will give more accurate data for analyzing. 

Safer From Jamming
  The signals which produced bye Block III satellites will be more better and will be safe from jamming. but intentional attacks may not be the only concern. Consumer-grade GPS jammers, which are illegal to sell or use but are nonetheless popular among commercial drivers who don't want to be tracked by their employers, also pose a safety risk.

                       The prototype that arrived at Lockheed Martin this week won't be launched into space. The first flight model will arrive next summer, with the goal of launching in May 2014. Ultimately the Pentagon wants to buy 32 satellites with the new technology, but we'll be using the existing technology for at least the next couple of years.
