What kind of a signal does a GPS give off?
Your hand-held GPS is a receiver. It listens to signals fromGPS satellites, and doesn't "give off" any signal of its own.
What does a gps satelite do?
A GPS satellite emits a very precise and accurate time signal that the receiver can use to calculate it's distance from the satellite.
How does a GPS receiver calculate its distance from a satellite?
Very easily. The GPS receiver measures how long it takes a certain radio signal to travel from the GPS satellite(s) to itself, and from that, the receiver calculates the distance. It can do that because it knows precisely how fast the radio signal travels.If you have signals from at least 3 satellites, the process of trilateration (not triangulation) pinpoints the location where the 3 distances 'cross' each other. If you have 4 satellites 'locked in', then you will find out your altitude, too. (The process is not quite this simple, but to go on would be confusing.)The hard part is measuring the precise time it takes for a certain radio signal to travel from the GPS satellite to your GPS receiver. Well, hard if you do it, but very easy when the GPS receiver does it!First, each GPS satellite carries an on-board atomic clock. This clock is outrageously accurate, but even so, ground stations connected to the US Navy atomic clock system keep each satellite precisely at the correct time. Your GPS receiver has an on-board high-precision clock of its own.Second, when your GPS receiver first makes contact with the constellation of GPS satellites, it is sent an 'almanac' that lists where each satellite is, what it's precise time is, and other goodies. After reading the almanac, the GPS receiver sets itself to the precisely same time as the satellite constellation.Thirdly, when the GPS receiver gets a signal from the satellites, there is information in it that says precisely at what time the radio signal left each satellite, which is identical for all the satellites. Then your GPS receiver 'looks at its watch' and subtracts the 'sent' time from the 'received' time. The data in the almanac are updated by the satellite constellation every few hours so that your GPS receiver will always know where the satellites are and what their precise time is.Go back to the beginning and reread what your GPS receiver can do once it knows the precise travel time of the radio signal.
What causes GPS interference?
GPS units calculate your position by measuring the distance to four satellites. Your GPS receiver does this by knowing the exact pattern that the satellite transmits, allowing you to know how long the signal took to arrive. Since the receiver knows exactly where the satellites are, it can figure out where you are. If the radio signal bounces from something like a mountain or a building, then it will take longer than expected for the signal from the satellite to reach your receiver. The receiver may calculate your position incorrectly.
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.
Does the palm 755p have gps?
No. You would need a separate GPS receiver and GPS software (i.e. TomTom) on your palm device to decipher the GPS receiver's signal into information you can use.

What can I do to fix this everytime I key up my CB radio it causes my GPS receiver to lose signal and I have to unplug it and plug it in again to get signal back GPS is outside opposite of antennae?
There is no way to solve the problem. Because of the high power of the CB transmitter and the low power of the satellite signals, the CB signal clips the GPS receiver, and it can even damage your GPS. The CB and the GPS unit work on entirely different frequencies, to be sure, but the fact that a several watt transmitter of any kind is right on top of a GPS unit can hammer the GPS. There is no way to "limit" the radiated power of the CB (if you still want it to work) so that it won't affect the GPS.
How does fleet GPS tracking help a trucking company keep tract of trucks on a highway?
A fleet GPS tracking system can help a trucking company keep track of trucks on a highway by sending a signal to the GPS receiver from the satellite and the GPS receiver will transmit data to a remote user every 90 seconds. This is how companies can keep track of the trucks on the highway.
How are gps' made?
using custom digital signal processing circuits, at least one standard microprocessor, and fancy RF receiver circuits.
The accuracy of GPS vehicle tracking method?
Newer Garmin GPS receiver WAAS (Wide area augmentation system) capability can improve accuracy, averaging less than three meters. No additional equipment or fees to take advantage of WAAS. Users can also get a better differential GPS (DGPS), to correct an average of three to five meters accuracy of GPS signals within range. To get the corrected signal, users must be out by the differential GPS beacon receiver and beacon antenna. Now we use the following GPS receiver for our bus railway system.
Where can I purchase a receiver for a gps module?
There are several GPS receiver modules available on Amazon.com. The Globalsat BT-359 - GPS receiver module has excellent reviews and cheapest price for the quality. You can find a link here: http://www.amazon.com/Globalsat-BT-359-GPS-receiver-module/dp/B000GWGHOK
Does a GPS work in Jamaica?
Yes, a GPS receiver will work in Jamaica.
