what does the phrase gps caddie meaN?
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.
What is the transmission media of GPS?
satellite signals
What does 'sat nav' mean?
"Sat nav" is short for satellite navigation, which refers to a system that uses signals from satellites to determine the exact location of a device or vehicle. It is commonly used in GPS navigation systems to provide accurate directions and maps to users.
What are the uses of UHF?
UHF (Ultra High Frequency) is commonly used for television broadcasting, two-way radio communication, GPS systems, and RFID (Radio Frequency Identification) technology. It is also utilized for wireless networking, satellite communication, and remote control devices.
How does a GPS receiver calculate its distance from a satellite?
Very easily. The GPS receiver measures how long it takes a certain radio signal to travel from the GPS satellite(s) to itself, and from that, the receiver calculates the distance. It can do that because it knows precisely how fast the radio signal travels.If you have signals from at least 3 satellites, the process of trilateration (not triangulation) pinpoints the location where the 3 distances 'cross' each other. If you have 4 satellites 'locked in', then you will find out your altitude, too. (The process is not quite this simple, but to go on would be confusing.)The hard part is measuring the precise time it takes for a certain radio signal to travel from the GPS satellite to your GPS receiver. Well, hard if you do it, but very easy when the GPS receiver does it!First, each GPS satellite carries an on-board atomic clock. This clock is outrageously accurate, but even so, ground stations connected to the US Navy atomic clock system keep each satellite precisely at the correct time. Your GPS receiver has an on-board high-precision clock of its own.Second, when your GPS receiver first makes contact with the constellation of GPS satellites, it is sent an 'almanac' that lists where each satellite is, what it's precise time is, and other goodies. After reading the almanac, the GPS receiver sets itself to the precisely same time as the satellite constellation.Thirdly, when the GPS receiver gets a signal from the satellites, there is information in it that says precisely at what time the radio signal left each satellite, which is identical for all the satellites. Then your GPS receiver 'looks at its watch' and subtracts the 'sent' time from the 'received' time. The data in the almanac are updated by the satellite constellation every few hours so that your GPS receiver will always know where the satellites are and what their precise time is.Go back to the beginning and reread what your GPS receiver can do once it knows the precise travel time of the radio signal.
Is there GPS technology available for my computer and, if so, how does it work?
PDA's can come with GPS technology and it works through the same function as other GPS systems, via satellite.
How does gps calculate its positinon?
by satellite.
What means GPS navigation?
Global Positioning Satellite. Actually it is Global Positioning System. but it is virtually the same thing.
Where can I find information about gps satellite tracking?
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

What is the transmission media of GPS?
satellite signals
What is the l band frequency?
The L band frequency ranges from 1 to 2 GHz. It is commonly used for satellite communications, GPS systems, and aviation navigation. Its longer wavelength allows for better penetration through obstacles like buildings and vegetation compared to higher frequency bands.
Can a satellite radio get gps signal?
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.
Why is the UHF frequency band used for GPS transmissions?
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.
Distance from earth to gps satellite?
The distance from Earth to a GPS satellite is approximately 20,200 kilometers on average. This distance varies as the satellites orbit the Earth. GPS signals travel at the speed of light, so the time it takes for a signal to travel from a satellite to a GPS receiver on Earth is used to calculate the distance. GPS relies on multiple satellites to provide accurate location information.

"Sat nav" is short for satellite navigation, which refers to a system that uses signals from satellites to determine the exact location of a device or vehicle. It is commonly used in GPS navigation systems to provide accurate directions and maps to users.
When was the first GPS satellite launched?
The first Global Positioning System (GPS) satellite, named "Navstar 1," was launched on February 22, 1978.
