What is mathematical principle behind GPS?
GPS positioning uses a three-dimensional triangulation method (called trilateration) to determine the location of the GPS receiver. Knowing the distance and location of multiple GPS satellites, the receiver can mathematically calculate the intersections of three (or more) spheres to determine its own location, using geometry in three dimensions. Trilateration is explained at http://en.wikipedia.org/wiki/Trilateration.
What is the minimum number of 'global positioning system' satellites that are observable by a user anywhere on earth?
A user can typically observe at least 4 GPS satellites anywhere on Earth to accurately calculate their position using trilateration.
How do GPS systems pinpoint locations across the globe?
GPS systems use the twenty-seven satellites that orbit the earth. The GPS receiver uses a mathematical equation similar to trilateration. The GPS receiver uses four or more of the satellites that are constantly orbiting the earth and use the information received to find it's location.
How does GPS work on a LG800G cellphone?
The LG800G cellphone uses signals from satellites to determine its location on Earth through a process called trilateration. The phone's GPS receiver picks up signals from multiple satellites to accurately pinpoint its position using algorithms. This information is then used by mapping apps and navigation systems to provide location-based services to the user.
How do p and s waves provide the location of the earthquake's epicenter?
P waves travel faster than S waves and arrive at seismograph stations first. By measuring the time difference between the arrival of P and S waves at multiple stations, seismologists can determine the distance to the epicenter of an earthquake. Trilateration is then used to pinpoint the exact location where the seismic waves originated.
How does trilateration work?
Trilateration is a method used to determine the position of a point by measuring its distance from three known points. By calculating the intersection of three circles centered at these known points with radii equal to the measured distances, the position of the point can be determined. Trilateration is commonly used in GPS systems to pinpoint a device's location by measuring its distance from multiple satellites.

How many BlackBerry phones have GPS support?
There are 200 million Blackberry phones which have been shipped. All of them have GPS capability. Some of the newer models have the ability to track the phone's location and provide coordinates to applications which need that information using trilateration rather than GPS. Trilateration is less accurate but saves on battery life.

How does a GPS technology work in a cell phone?
Cell phone gps tracking software is software that trilaterates (or triangulates) your location using 3 satellites in space. You can track someone yourself, if they have gps on their phone, using trilateration.

How does cell phone gps tracking work?
It's done with trilateration. Read more here http://hubpages.com/hub/How-Does-GPS-Work-In-Cell-Phones
What 2 coordinates is the global positioning system based on?
The Global Positioning System (GPS) is based on trilateration, which requires a minimum of three satellite signals to determine a user's position in terms of latitude, longitude, and altitude. GPS uses time signals from at least four satellites to calculate accurate coordinates for a specific location.

The LG800G cellphone uses signals from satellites to determine its location on Earth through a process called trilateration. The phone's GPS receiver picks up signals from multiple satellites to accurately pinpoint its position using algorithms. This information is then used by mapping apps and navigation systems to provide location-based services to the user.
What satellite based system helps us locate places on earth?
The Global Positioning System (GPS) is a satellite-based system that helps us locate places on Earth with accuracy. It consists of a network of satellites that transmit signals to GPS receivers, allowing users to determine their precise location using trilateration. GPS is widely used for navigation, mapping, and various location-based applications.
How do p and s waves provide the location of the earthquake's epicenter?
P waves travel faster than S waves and arrive at seismograph stations first. By measuring the time difference between the arrival of P and S waves at multiple stations, seismologists can determine the distance to the epicenter of an earthquake. Trilateration is then used to pinpoint the exact location where the seismic waves originated.
Where does a gps receiver get its signal from?
A GPS receiver obtains its signal from a constellation of satellites orbiting the Earth, specifically the Global Positioning System (GPS) satellites. These satellites continuously transmit radio signals containing their location and time information. The GPS receiver picks up signals from multiple satellites, calculates the distance to each one, and uses this data to determine its own precise location through a process called trilateration.
