probably not, as the Global Positioning System uses data from several satellites to calculate the receivers position. At any given time, there are usually at least 4 GPS satellites above the horizon from anywhere on Earth. Only interference on the GPS frequency can impair the accuracy.
No.
GPS is a radio signal. Metals block radio signals. Aluminum is a metal.

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.
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.
from satellites in orbit.
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.
transmit a jamming signal on its L1 and L2 carrier frequencies.
Any GPS can lose its signal. Even military grade GPS can encounter those problems. However, it's overall a good brand of GPS and you shouldn't let the possibility of a lost signal keep you from your purchase.
A gps map is only as reliable as your access to Satelite signal. Camping in certain areas where the satelite signal is strong will allow you to be able to access gps map wherever you go.
Your hand-held GPS is a receiver. It listens to signals fromGPS satellites, and doesn't "give off" any signal of its own.
Traditionally the best GPS for signal speed is a Garmin GPS. These are built with high quality materials and are traditionally more accurate when it comes to signal speed.
