Radio marine GPS systems are satellite powered radio signals that has two kinds of transmissions, the C/A code and the P – code.Standard Positioning Service technology makes use of Coarse Acquisition or the C/A signal.One advantage of C/A signal is that it takes less time to affix a specific location because it can acquire signals faster.This signal is also commonly used by the military to jam other radio signals and is used to send out spoof or falsely broadcasted signals.On the other hand, a P – code signal is a signal that provides a precise and exact locations and this is also difficult to jam or to spoof.Again, the P – code signal is commonly used by the military because it can easily be encrypted in such a way that only receivers specifically designed to receive the signal can decipher the data.In radio gps technology, P – code signals are also known as Precise Positioning System.These two radio gps signals are widely used in practically every piece of mobile electronics, cars, business phone systems and sometimes even high end appliances....
