GPS Satellites use two frequencies 1.57542 GHz and 1.2276 GHz.
AIS operates in the Marine VHF band using channels 87B, 161.975 MHz and channel 88B, 162.025 MHz
A GPS satellite emits a very precise and accurate time signal that the receiver can use to calculate it's distance from the satellite.
A GPS stands for Global Positioning Satellite and is a device which uses satellite location to determine your position. A caddie is a device which is a container or carrier for another item. As such, a GPS caddie is an item which holds a GPS.

GPS stands for "global positioning satellite."
Global Positioning System (GPS) uses the signals from geosynchronous satellites to provide accurate position information for navigation. As such utilizing GPS for navigation amounts to utilizing satellite navigation ("sat nav"). Note that while GPS, which was developed by the US government is the most widely used satellite navigation system, Russia also has the Global Navigation Satellite System (GLONASS) deployed which can provide essentially the same satellite navigation capabilities - and can be used in along with GPS to get faster and more accurate position information. The EU, Japan, China, and India are also working to deploy a satellite navigation systems.
PDA's can come with GPS technology and it works through the same function as other GPS systems, via satellite.

Here's a link to a website that offers a lot of interesting information to learn about GPS satellite tracking. http://www.edu-observatory.org/gps/tracking.html

Global Positioning Satellite. Actually it is Global Positioning System. but it is virtually the same thing.

No. The satellites used to distribute Sirius/XM "satellite" radio operate on frequencies assigned to Sirius/XM "satellite" radio. They don't operate on frequencies allocated to the GPS system.
The UHF frequency band used for GPS transmissions for clear reception and sending. UHF or ultra high frequency is meant for radio frequencies between 300MHz and 3GHz. Normal frequencies for GPS transmissions are 1575.42 MHz and 1227.60 MHz. UHF frequency band covers these GPS frequencies.
