How does a GPS satellite work with a GPS device?
signals from at least 3 satellites send signals to and receive signals from the gps which are then triangulated to give the exact position of the GPS unit. Most GPS units are receive only. That is they must receive positional and timing information from the GPS satellite constellation. The internal processor them computes your position based upon this data(triangulation). Generally receiving data from three or more satellite's is needed to be produce a good fix (your position) but this is also dependent upon the geometry of the satellites. The best fixes are obtained when you have signals from three or more satellites which are geometrically separated by 45 degrees.
What satellite helps us locate places on earth?
The Global Positioning System (GPS) is a space-based satellite navigation system that consists of a series of satellites used for locating places anywhere on or near the Earth. GPS became fully operational in 1995.There are also a number of satellites that take high-resolution imagery of earth including GeoEye-1, QuickBird, WorldView-1, WorldView-2, and others. High-resolution images combined with a precise location can help to locate any place on the planet.
What are some of the types of information obtained by remote sensing?
Remote sensing is the examination or the gathering of information about a place from a distance. Such examination can occur with devices (e.g. - cameras) based on the ground, and/or sensors or cameras based on ships, aircraft, satellites, or other spacecraft.
Where is past years satellite images available online?
For past years earth-based satellite imagery in Google Earth you can select 'Historical Imagery' under View menu. This shows a timeline slider from which to select available satellite and aerial imagery from the past. NASA also provides vast archives of satellite imagery much of which are available online such as the NASA Image Gallery
Explain how a communications satellite is used?
http://library.thinkquest.org/03oct/02144/basics/satcomm.htm Satellite Communication Satellites have now become an integral part of the worldwide communication systems. Although long-range and long distance communication took place much before the introduction of satellite systems, they had a lot of disadvantages. Point - to - point communication systems are very difficult in the case of remote & isolated locations, which are surrounded by oceans, mountains and other obstacles created by nature. The satellite is nothing more than a radio-relay station But, they have one potential advantage- The capability of a direct line of sight path to 98% (excluding the polar caps, which are in accessible to satellites) of the earth's surface. One of the most important event in the history of satellite communication took place when COMSAT or communication satellite corporation, launched four satellites within 6 years that is between 1965 to 1979. The first of these series was the 'Early Bird' , which was launched in 1965. This was the first communication station to handle worldwide commercial telephone traffic from a fixed position in space. The next series INTELSAT was a group of satellites that served 150 stations in 80 countries. ..................................... get the points and write the essay urself
Pictures of the surface based on data collected by landsat are called?
Satellite Images.
What is a SAT NAV GPS, and where are they available?
A SAT NAV GPS is a satellite navigation system. It actually triangulates your position on the planet with the satellites and tells you where you are based on the latest satellite images and maps of the earth. Best Buy has both TOM TOM and OnStar and that's where I would recommend buying one.
What satellite discovered Pluto?
No satellite did. Pluto was discovered by Clyde Tombaugh, who found it using a ground-based telescope in 1930, long before we launched the first satellites.
How do you get satlliete images?
Obtaining satellite images is a relatively straightforward process. Generally the images are acquired from a satellite imaging provider such as DigitalGlobe or Planet Labs. The images can be purchased directly from the provider or through a reseller. Once the images have been purchased they can be downloaded from the providers web-based ordering system. Step 1: Choose a satellite provider. Step 2: Purchase the desired satellite image. Step 3: Download the satellite image from the providers ordering system.Many satellite images are also available for free from government agencies such as the U.S. Geological Survey (USGS). The USGS provides satellite images from the Landsat program which is a joint effort between the USGS and NASA. Landsat images can be accessed through the USGSs EarthExplorer website which provides a searchable database of satellite images.

The global positioning system is a network of satellite plus?
The global positioning system is a network of 24 satellites plus ground based receivers.
How many people saw the inaugural address of obama?
Between 800,000 and 3,000,000 (800,000 was based on a satellite image) (3,000,000 was based on video obtained on-site)
What has the author John Kiesling written?
John Kiesling has written: 'Study of advanced communications satellite systems based on SS-FDMA' -- subject(s): Artificial satellites in telecommunication, Earth stations (Satellite telecommunication)
We saw a satellite that was real bright how can we find out if it was the ISS?
Go to the related link - a java based program from Nasa to tell where certain satellites including the ISS are.
What could one do on the website FlashEarth?
One can view satellite and aerial images of Earth on the FlashEarth website. FlashEarth uses a flash-based interface, and allows one to zoom in on images.

How is a communication satellite is used?
A communications satellite operates as a transceiver (TRANSmitter - reCEIVER). Signals from a base station on Earth are sent to a satellite receiver. The data is either stored for a period of time or sent immediately to a transmitter on the same satellite. The transmitters on satellites are positioned to transmit towards Earth or towards other satellites. A base station on Earth will receive the transmitted signals and pass them to land based equipment. As satellite signals rely on line of sight, they each have a range over which they can send signals. Too far round the Earth and the signal won't make it. That's why they can also transmit to other satellites before the signal is finally returned to Earth, far round the globe. The data carried by communication satellites is used for a wide variety of applications. Television, telephones, computer networks and far more are regularly sent to and from satellites.
