Do TVs use satellites in space?
Some TV receivers, such as DirecTV and Dish Network, do receive signals beamed from satellites. If you see a dish-shaped antenna pointed up, that's a location that uses satellite TV. Even if your system does not receive direct satellite signals, many of the programs that you watch are most likely transmitted via satellite at some point in getting the program to you.
How many satellite signals do you need to get an accurate signal on a GPS?
at least 3. Alan x:)
How does a GPS receiver work?
A GPS (short for "Global Positioning System") is an electronic device that measures its distance to three or more satellites to determine its precise location. There are 24 such satellites in fixed orbits around the world. All of the satellites are perfectly synchronized, and send out digital radio transmissions broadcasting the current time. Your GPS receiver receives three or more of these signals, where the distance to the satellite will delay the signal just a tiny bit. The GPS receiver uses the relative delays to determine its precise location. GPS receivers are available from Garmin, Magellan, Tom Tom, and a number of other companies. Many newer cellphones also have a built-in GPS receiver.
Is gps ground based only?
No..... there are many uses for GPS and they are not limited to ground. They are used in planes, boats and a multitude of other applications. Look at www.findvehicle.net the have a system that can be used on anything.
What are the benefits of broadband satellite?
There are many benefits associated with broadband satellite. One of the most noted benefits is the convenience of receiving service in a remote location.
How and why do you use satellites?
{| |- | Satellites are used for many purposes. Pictures of cloud patterns and other atmospheric events are used in weather prediction. They can receive and re-transmit all types of communications signals. This includes television, telephone calls and satellite radio signals. The can provide data that allows the Global Positioning Devices to pinpoint your current location. |}
How many television stations use satellites?
Almost 90 percent of public and private television stations transmit signals via satellite
Do satellite dishes provide better reception than cable service?
I believe that satellite dishes do provide better reception than cable service. I believe this because satellite dishes are bigger and getting their signals from huge satellites in space. They have less interference factors that affect them than cable service does and they are less likely to go off air as often happens with cable service. Satellite dishes also offer all HD channels where as with cable you have to pay an extra fee for HD many times. I think that satellite dishes receive stronger signals and are better equipped to interpret those signals than cable service is. I also believe that the satellite signals are jumbled less often than cable tv and because of this you get a clearer picture and more channels.
How can pet scans determine the location of a tumor?
Many sources agree that pet scans are effective in finding cancer. These scans are said to help determine the location of tumors and whether or not they have spread.
How does the proper satellite signal get to the TV channel?
The correct signal for satellite TV is determined by the direction the satellite dish is pointed. DirecTV and Dish Network signals come out of the Southern sky from the direction directly above Texas. Many other satellites orbit the earth and send out audio and video signals of all different types and formats. Simply put, a satellite dish is like a catchers mitt and will catch any signal coming from the satellite it is aimed towards. The signal received will need to be properly matched with the in house receivers and equipment in order to work properly. For example, if a Dish Network dish is aimed towards a DirecTV satellite signal, the system will not work.
Does GPS represent an invasion of your privacy?
GPS technology can raise privacy concerns because it tracks and records an individual's location data. If usage is not controlled or unauthorized access is obtained, there is potential for invasion of privacy. However, many GPS services have privacy controls in place to protect user data and ensure consent is given before tracking location.
Are Global positioning satellite systems radars?
The various GPS systems in several countries employ satellites that do not use RADAR. The reason is that it's your GPS receiver that determines where you are on earth based on -Radio- signals sent from each visible GPS satellite. How it works is this . . . the satellites transmit radio signals to earth. Your GPS receiver detects and 'reads' these radio signals. The radio signals send a lot of information, but the most important is the precise time, based on an internal atomic clock in all 32 satellites (24 of which are 'on' at any given moment) (All adjustable from one of several ground stations). Your GPS receiver, using its own precise time clock (frequently set to match the satellite's time) uses the length of time that the radio signal takes to make it from the satellite(s) to your location. Since the speed of radio waves is precisely known, the GPS receiver uses a very simple formula to calculate the distances from all the satellites that it has 'locked into'. The GPS receiver picks the 3 best signals to obtain distances from, and comes up with a good location of the receiver. The receiver can show this information on a map, either handheld or in your car, or present you with map coordinates in the form of latitude and longitude - these being useful to surveyors and others. For various technical reasons, readings from a 4th satellite are required, but 5 'locked in' satellites are often the fewest that it is practical to use. The best GPS receiver setups can determine the accurate location of the receiver (therefore, your position, also) as close as 1 centimeter (length of a sugar cube), up to within several yards. This accuracy largely depends on how many satellites are 'locked in', and how expensive the receiver is. (How many 'extras' it contains to improve accuracy. Example - I use a GPS receiver with several extras in it, and can get an earth location within 4 inches of the actual location. The cost was about $6,000 for the receiver itself. A car-mounted Tom-Tom type receiver, on the other hand, only needs to know where you are within several yards, has fewer 'extras' and costs somewhere around $200.
