One GPS satellite can serve an unlimited number of receivers, if they have
unobstructed line-of-sight.
GPS receivers need to see a minimum of 4 satellites in order to calculate an
accurate 3-dimensional position. Almost all of them have the ability to work
with up to 12 satellites simultaneously, if they can see that many.
Yes, there are many GPS with FM transmitter.
You need both a radar antenna and a GPS radar if this is marine then the radar antenna will perhaps include a Receiver and Transmitter as well and the GPS maybe a mushroom shape
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.
There is not, unfortunately.
FM GPS Transmitters use radio frequencies to track and locate objects from far away. They are more so common in vehicles and cellphones: http://www.gpstrackingdevice.net/Accurate-Tracking-With-FM-GPS-Transmitter-Devices.html
Any GPS with a FM transmitter.
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.
The Samsung Galaxy S smartphone offers the following features: DLNA, FM Receiver, FM Transmitter, GPS Navigation and HD Playback. I hope this is enough answer for you.
The GPS receiver in your GPS unit cannot do this, it only provides the GPS fix, quality of the fix (typically as CEP), and whether fix is 3D 2D or No fix. It is the responsibility of the navigation computer connected to the GPS receiver to determine if dead reckoning is needed, how to do it, and what indication if any should be given. I have seen units give no indication at all then show impossible driving moves, while other units (e.g. the TomTom) grey the entire screen in that mode.
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
A GPS receiver gets its signal from a network of satellites orbiting the Earth. These satellites continuously transmit signals that the GPS receiver uses to calculate its position and determine accurate time information. By receiving signals from multiple satellites, the GPS receiver can triangulate its position with high precision.
Many smartphones support GPS apps including the iPhone and tHe Blackberry. If your current phone does not support GPS apps, you can purchase a GPS receiver chip.
