The original GPS system was invented and put together by the US Military. Orginally, it required huge radio receivers, big power supplies, and substantial antennas.
With the miniaturization of electronic parts and computer chips, GPS receivers were invented that put the power supply (batteries) and the radio receiver in a backpack. The antenna became easier to carry, and looked like a saucer on top of a pole.
Today, all of the above are so small that they can be put in a tiny space . . . battery, antenna and receiver. This is a 'Stand-alone' GPS receiver . . . it works all by itself and needs no other equipment.
Smartphones use GPS receivers to receive signals from GPS satellites and determine their location. GPS receivers in smartphones work by triangulating the signals from at least four GPS satellites to calculate the phone's latitude, longitude, and altitude.
The Navman GPS receivers have an overall rating as good. They are fairly solid and easy to use but their is better functianality out there.
GPS receivers are placed on the ground on opposite sides of the fault. Data is collected to show the movement of the receivers.

yes people from the cia can trace any gps they want to.
GPS (Global Positioning Systems) were the 'in' gadget to own for the tech-savvy motorist. However, with the advent of more complex smartphones, which have GPS and do lots more besides, the stand-alone GPS is not as popular.
There are many online sites that are popular for purchasing GPS receivers. One site is the Best Buy website. They have a large selection to choose from.
There are hand held garmin gps receivers you can purchase. These are used for both driving and walking. Also a garmin watch is for both purposes.
GPS itself does not do this. When geologists place recording GPS receivers on opposite sides of the faults that separate the tectonic plates the receivers calculate their positions (just like the GPS navigator in a car does) and when the geologists analyze the collected data they can make maps of plate movements.
No ipod touches have GPS receivers.
GPS stands for Global Positioning System. It is a network of satellites that orbit the Earth and provide location information to GPS receivers.
