Every satellite in the GPS constellation of 24 to 36 satellites orbits the Earth,
and at least four (4) of them are visible from any point on Earth at any time.
Wherever on Earth you take your GPS receiver, it will work with the satellites
and calculate your position. The system itself has no boundaries.
But ... during the 1990s and early 2000s, I travelled to a few countries where
they didn't allow you to bring a GPS receiver into the country. I interpreted
this policy to be either an economic one ... an attempt to protect their
domestic nonexistent GPS manufacturing industry from cheap imports ... or
else a political one, with the continued operation of the national government
dependent on maintaining the population in a perpetual state of not knowing
which way is up.
I don't know whether any countries still restrict the inflow of GPS in tourists'
pockets. With the technology now present in most portable telephones, it
seems that it would be pretty tough to restrict it today.

∙ 12y agoThe standard GPS pulls data from over 50 satellites at a time. They use data from all of the satellites in conjunction with one another to provide you with helpful location data.

How many satellites are included in Global Positioning System?
The Global Positioning System (GPS) currently consists of a constellation of 31 operational satellites. These satellites are spread out in six orbital planes, approximately 20,200 kilometers above the Earth's surface.
What is expansion of gps and gis how many satellites are there in gps?
Globle positioning system
How many users can the global positioning system have?
The 24 GPS satellites really have no practical limit on the number of users. All the satellites do is to transmit a radio signal. There could be a billion GPS receivers that could all be using these radio signals at once. Or more.
Does global positioning system navigation work everywhere in the United States?
Yes. In fact, because many satellites orbit our earth, Global Positioning Satellite (GPS) systems work anywhere in the world, as long as there is an unobstructed view of the sky. Most, if not all GPS units sold in North America have pre-installed maps of the United States and parts of Canada and Mexico. Travel outside of the country will require the purchase of location-specific maps.
Do You Really Know How GPS Tracking Systems Work?
When many people think of a GPS tracking system they're really thinking about GPS receivers. These are the basis of navigational aids that receive signals from satellites in the Global Positioning System and use trilateration to determine the unit's location. GPS tracking systems utilize a separate connection to the GPS receiver to acquire its data. Some GPS-capable devices don't provide information wirelessly, but historical location data can be downloaded when the device is connected to a network.
How many Global Positioning Systems are there around the world?
Receivers or satellites? The US has over 22 GPS satellites in orbit. The Russians have their system, the EU is getting ready to launch a system, too. Don't know about the Chinese.

What is Earth's three satellites called?
The planet Earth upon which we live has precisely one natural satellite, which is known as the moon, or Luna, and it has a great many artificial satellites, including the International Space Station, communication satellites, surveillance satellites, global positioning satellites, etc.
What are the kinds of artificial satellites that orbit our planet today?
There are many kinds of artificial satelliets orbit our earth they are used for many purposes for communication, GPS(global Positioning system). for television etc.

How many satellites do you need to find your location?
A single satellite can only give you relative location. 3 satellites can give a 2-D positioning/location that includes longitude and latitude. 4 satellites can give a 3-D positioning/location that includes longitude, latitude and altitude. Only 4 satellites can give you absolute location.
What do you understand by the co-ordinates of a map?
Coordinates on a map are used for navigation. Many ships and aircraft use coordinates to travel vast distances. Coordinates are also utilized by GPS (Global-Positioning Systems).
Can I keep track of a rental car with a global positioning unit?
Yes, there are several GPS systems available that will easily track and give many reporting features. Take a look at www.findvehicle.net they have a great system.
How and why do you use satellites?
{| |- | Satellites are used for many purposes. Pictures of cloud patterns and other atmospheric events are used in weather prediction. They can receive and re-transmit all types of communications signals. This includes television, telephone calls and satellite radio signals. The can provide data that allows the Global Positioning Devices to pinpoint your current location. |}
How do modern oceanographic vessels determine their position?
They use GPS (Global Positioning System) where the ship etc searches for as many radio signals from geosynchronous orbit satellites as it can get. It then triangulates its position by determining the direction and angle that it receives the signals. Same process that modern airliners use.
