GPS satellites are used to monitor faults by tracking the movements of the Earth's surface. By placing GPS receivers near fault lines, scientists can measure the precise changes in position caused by tectonic movement. This data helps in understanding the rates and directions of fault movements, which can be valuable in assessing earthquake risks.
GPS satellites do not 'find' anything, that is not their purpose.
A minimum of 4 satellites is needed to obtain a full GPS signal. These satellites are used to triangulate your position accurately on Earth.
GPS satellites monitor faults by using their precise positioning capabilities to detect minute changes in the Earth's crust. They measure the time it takes for signals to travel between satellites and ground stations, allowing for the detection of shifts in tectonic plates. By analyzing these positional changes over time, scientists can identify patterns or anomalies that may indicate the buildup of stress along fault lines. This data is crucial for assessing earthquake risks and understanding geophysical processes.
GPS devices receive data from satellites through signals transmitted by the satellites. The GPS receiver in the device then processes these signals to determine the device's location based on the time it takes for the signals to travel from the satellites to the receiver. This location data is then used to provide navigation information to the user.

Satellites can be used to collect data on earthquake faults by monitoring ground movements using radar or GPS technology. This data can help track the strain building up along faults over time, which can be crucial for predicting and understanding earthquake activity. Additionally, satellites can provide high-resolution images to identify surface deformations near faults, aiding in seismic hazard assessments.

A minimum of 4 satellites is needed to obtain a full GPS signal. These satellites are used to triangulate your position accurately on Earth.
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.
GPS satellites work by constantly transmitting signals that are picked up by GPS receivers on Earth. Each satellite sends out signals containing information about its position and the current time. By receiving signals from multiple satellites, a GPS receiver can determine its own position through a process called trilateration, which calculates the intersection point of the satellite signals to pinpoint the receiver's location on Earth.
