GPS satellites can be used to monitor faults by measuring subtle changes in the Earth's crust. By continuously tracking the movement of the Earth's surface, scientists can detect and study fault activity. GPS receivers on the ground collect data on the satellite signals, allowing for precise measurements of tectonic plate movement and deformation, which provides valuable information about fault behavior and potential earthquake hazards.

Geologists have created Creep Meters, GPS Satellites, Range/ Laser devices, and Tilt Meters. These instruments help keep track of changes in the land surface and elevation.- Polly T. Denver, CO
GPS satellites do not 'find' anything, that is not their purpose.
GPS satellites are used to help us accurately determine the current time and our location. GPS satellites are not directly used to help us predict the weather. Weather satellites use many imaging and sensing technologies to help us predict the weather, but they are not useful in helping us determine our location. They are two different types of satellites with two different purposes. There are many other types of satellites too, such as communication satellites (such as used with Direct TV), space telescopes (such as Hubble) etc.
GPS uses satellites that were placed into orbit by the Department of Defense. The government set up the entire network on their own, and it is free to use as long as you already have a GPS device.

Scientists can monitor changes in elevation as well as horizontal movement along faults using a network of Earth-orbiting satellites called GPS.
Geostationary satellites are the ones used for GPS satellites.

Global Positioning Systems (GPS) use trigonometry. There are a number of satellites orbiting the earth. The GPS uses the time signals sent by these satellites to establish the distance to the satellites. Trigonometry is then used to find the location of the GPS unit.

There are currently 30 healthy GPS satellites in orbit.
