Another application of GPS is, it is used in airplanes to navigate in cloudy and rainy weather. It is also used by surveyor to check the accuracy of their work.

GPS is also used in sports for e.g.: in racing car, hiking, boating and much more to keep track about their where about.

Another GPS implementation is made in unmanned managed coal logistics to the ship. GPS equipment improves timing of operations such that barges can be tracked and loading of coal onto ships is better timed. These days GPS is also used to study the plate moment over the land to predict the next earthquake, this can save life and money both if accurate predication is made well before.
Few sources where updates on GPS gadgets and technologies can be found are 1) NASA has developed GPS Application Exchange to promote GPS technology. 2) Another important resource is GPS World, a monthly publication that publishes latest updates and news
GPS virtually works anywhere, except deep inside the building, in caves and some very remote areas. It can be used in multiple ways and is virtually free and comes in many make and model.
