GPS receivers don't transmit anything. 15 people all sitting around the same
picnic table outside should be able to all take out their smartphones and study
their GPS positions. Nobody's GPS should bother anybody else's, and it would
be an easy and foolproof way to avoid any human interaction.

∙ 15y agoWhen a gps interacts with a satellite it sends data back a and forth to try to triangulate its location. To triangulate you need at least 3 satellites in view but more are better. The more power the gps has the better the data will be received and transmitted. Taking all this into account we come up with this. Also objects can obstruct this data path. -Battery power -Number of satellites in range -Power and quality of gps transmitter and receiver -Whether or not this path is being obstructed by something such as lead, rock, mountains, or if you are in a canyon or something.

How can a gps system be blocked or jammed?
GPS signal jammers are portable devices that literally means gadgets that stop a GPS tracking device from receiving the signal that without which they cannot pick up their position. They emit their own signal at the frequency that GPS tracking devices use, which confuses or blocks other GPS signals.
What do GPS satellites do?
GPS satellites orbit the earth, around 20,000Kms above us. They contain very precise atomic clocks which they use to produce a special timing signal which is then broadcast back to earth. Back on earth, we can use our GPS receivers (Like Sat Nav) to pick up the GPS signals, and by using very clever mathematical algorithms in conjunction with the timing signals we receive from the satellites, calculate our position on the surface of the earth.
How do satellites know which gps is yours?
They don't, any more than the TV station's transmitter knows which TV is yours.They don't need to know. They just keep driving around in orbit up there,transmitting their names and their time signals. They don't need to know whois listening, or how many are listening, or even if anybody is listening at all.Your GPS, and somebody else's on the other side of the parking lot, can bothlisten to the exact same signals, and show different locations. It's all done inthe GPS receiver in your hand. Howit's done is the whole beauty of GPS.
What is the neuron part that picks up signals from other neurons?
Dendrite
How does a GPS receiver work?
A GPS (short for "Global Positioning System") is an electronic device that measures its distance to three or more satellites to determine its precise location. There are 24 such satellites in fixed orbits around the world. All of the satellites are perfectly synchronized, and send out digital radio transmissions broadcasting the current time. Your GPS receiver receives three or more of these signals, where the distance to the satellite will delay the signal just a tiny bit. The GPS receiver uses the relative delays to determine its precise location. GPS receivers are available from Garmin, Magellan, Tom Tom, and a number of other companies. Many newer cellphones also have a built-in GPS receiver.
What does orbiting satellites that send radio signals to a receiver on Earth make up?
GPS system
Choosing a GPS Receiver?
When choosing a GPS receiver, it's important to understand the differences between different products on the market. Most GPS receivers are designed to receive signals from the United States GPS network. However, Russia has its own GPS network too. Some newer GPS receivers are designed to pick up signals from both the US and Russian system. In many cases, receivers that are designed to pick up signals from both these systems can lock on to one's destination faster. In addition, they often offer better reception in city environments with tall buildings and other obstructions. In some cases, dual-purpose GPS receivers can lock on to an individual's location while he or she is in a subway or building.

What is the need for other countries to launch other GPS systems when the U.S. has already put up a GPS system that others can use?
The need to develop independent positioning system is obvious - independency. US started the system and opened it for the world to use. Imagine one day somebody from the US Gov. will decide to code the signals transmitted from the orbital group of satellites and make our investments to the equipment just a useless pieces of hardware. And plus,almost all countries hate us, so we would definetly be srewed if they decited to mess it up!!!

Does gmail mess up other emails you have?
no it does not.
What do Satellites have to do with cellphones?
with calls themselves, nothing. however all current cell phones have a GPS receiver that picks up and decodes the signals from GPS satellites so their position can be accurately determined for emergency 911 calls.
GPS tracking from a cell phone.?
Yes GPS tracking can still pick up signals in remote areas however they may not show a real time display as it would when you are in a more populated area. Most GPS tracking in remote areas is displayed through a satellite up-link and can take time to send and receive images from that up-link location.

How do police spy on cell phones?
It can be done by triangulating signal strengths to the cell towers. GPS is not required, but can provide a more precise location if the phone can pick up the satellite signals, in which case the phone reports the GPS location to the cell towers.
