GPS SYSTEMS 
A.)  The GPS Systems is a satellite-based navigation system made up of a network of 24 satellites placed into orbit by the U.S. Department of Defense. The GPS is originally intended for military applications, but in the 1980s, the government made the system available for the public. This system works in any weather conditions, anywhere in the world, 24 hours a day.
B.) This innovation has impacted peoples daily life when wanting to go to certain places they have never gone to. This innovation has allowed people to going anywhere they desire without the fear of getting lost.
C.) So far this innovation has solved the problem of allowing people to go anywhere without being afraid of getting lost in an unknown place. People usually stopped themselves from going anywhere because they aren't familiar with the places surrounding, but with the GPS you can now go anywhere you desire and even finding helpful places you might need when traveling by car.
D.) I think this method has allowed people to go to desired places knowing that the GPS is accurate. Today's GPS receivers are extremely accurate, thanks to their parallel channels are quick to lock onto satellites when first turned on. Garmin GPS receivers with WAAS capability can improve accuracy to less than 3 meters on average.
