What are up link and down link frequencies of gps?

That might help
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.
Light is made up of radiation of different wavelengths/frequencies; our eyes can perceive some of these differences in wavelengths/frequencies.

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…
Yes, because my dad used a GPS while traveling from Florida to New Jersey in a car to make it easier to get from destination to destination. NO! GPS And satellite radio are two different things. They cannot share an antenna. GPS and Radio are on 2 different frequencies GPS, GPS travels on a L1 Frequency up to 1575 MHz while radio is on BANDS, Like Sirius is on S band which holds DATA and…
This is done to avoid crosstalk. If, for example the up and down -links were on the same frequency, it would work much like a walkie-talkie, meaning only one person could send, and one receive, at any given point in time. By giving each direction its own carrier wave, it allows both deviced to send and receive simultaneously, which greatly speeds communication.
Hand held gps systems would not be good for young drivers, because they are inexperienced drivers. They could end up crashing their vehicle or running off the road, because they are paying more attention to their hand held gps unit.

It is much easier to build a satellite transponder using different frequencies for the two directions (frequency division duplex, FDD). A single frequency (time division duplex, TDD) satellite link is possible, but then all earth terminal must be carefully synchronized. The satellite transponder and the earth terminals would be more expensive, the whole network would be more complex and less reliable. There is also a historical reason. Frequency bands were allocated decades ago and changing…
How do you hook up car speakers and a sub to a car amp when you want the speakers to play full high frequencies and the sub to play the low frequencies?
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.
A good place to find Garmin GPS devices in lots of 5 or more is on eBay. http://www.ebay.com/ Using the search words 'garmin wholesale' should bring up the current auctions. eBay is also a great place to find a single device at a great price. Using this link to Nextag http://www.nextag.com/Garmin--500003/garmin-GPS-wholesale/brand-html, you can find a list of online stores with models and prices of many Garmin GPS models.
