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.
i cant think of anything . i have a gps system w/ blue tooth and sirius and have never got any glitches or anything. maybe its your system, antenna or wires.
GPS is a radio signal. Metals block radio signals. Aluminum is a metal.
Clouds interfere with radio signals because the density of the cloud can cause static with the radio signal. The air can also interfere with the signal.
from satellites in orbit.
No, GPS uses microwave/radio signals which are unaffected by magnets.
transmit a jamming signal on its L1 and L2 carrier frequencies.
Transmit another signal using the same carrier frequency to interfere with the original signal...also known as "jamming". If you have two signals using the same carrier frequency, and you add a second signal source with the same carrier frequency, and an a stronger amplitude (intensity), but different signal data, then it mixes with the original signal at the receiving end, and the original signal cannot be clearly decoded.
There are two ways to do it, first and the most accurate is by satellite GPS, the GPS receiver have to log on to 3 or more satellites and it can determine the precise coordinates and even the speed it is flying, the other one is by sending a signal out and wait for the bounced signal and measure the time from sending to receiving the signal but that will only give the height above ground level and not above sea level
As long as the GPS vehicle locator receives signal in Antarctica then it should function properly. You should check with the company that supplies the GPS signal and confirm they have coverage in Antarctica.
