what
A minimum of 24 operational Navstar satellites are required for the GPS system to work effectively. These satellites are strategically positioned in orbit to ensure global coverage and accurate positioning for GPS receivers on Earth.

a GPS device will need at least 3 satellite locks to work.
You can use a GPS anywhere the satellites shine.
GPS
A minimum of 4 satellites is needed to obtain a full GPS signal. These satellites are used to triangulate your position accurately on Earth.
You would need at least three GPS satellites to pinpoint your location. However, you would need a fourth to also identify your elevation.
No, for GPS to work there must be 24 operational satellites in orbit, with 12 of those above the horizon as seen from any point on earth.For a GPS receiver to get a latitude-longitude fix it must receive signals from a minimum of 3 satellites and to also get altitude it must receive signals from a minimum of 4 satellites. Each satellite that it receives above these minimums allows the receiver to get a more precise fix.
A GPS works by satellites that are located in outer space. These satellites are connected with cameras that show the whole earth. You GPS and the satellites systems are working together to provide maps for you.
Sattrack is a system used to monitor satellites' positions and orbits, while GPS (Global Positioning System) is a network of satellites that provides location and time information to GPS receivers on Earth. In essence, sattrack is more specific to tracking satellites, whereas GPS is a broader system for determining precise location on Earth.
At least four GPS satellites are required to pinpoint a location on Earth's surface accurately using trilateration. Three satellites are needed to determine a two-dimensional position (latitude and longitude), while the fourth satellite provides the altitude component.
