what is difference between geostationary and geosynchronous sateelites?
102417
A geostationary orbit requires that the satellite be in an orbit directly above the equator and approximately 22 236 miles (35,786 km) above sea level.  This orbit puts the satellite in a position where it is always directly above the same spot on the planet at all times.\n\nA geosynchronous orbit means that the orbit period of the satellite is the same time period of the sidereal rotation period of the Earth.  In layman's terms, the satellite will be at the same locations over the earth at the same time every day.\n\nWith a geostationary orbit, the satellite will appear from Earth to be fixed in the same location in the sky all the time.  With a geosynchronous orbit, the satellite will appear to move in the sky in an analemma or figure-8 pattern in the sky but would appear in the same spot every day at a certain time. (e.g. If the satellite was directly overhead at midnight on one day, it would appear directly overhead every day at midnight.)

3-\nGOES-10 (West) and GOES-12 (East).  Goes-11 is in orbit but is not in operation; it is in case GOES-10 or GOES-12 has a problem it can take over while they are being repaired.\n\n**These are meteorological satellites.  As far as total geosynchronous satellites, there are approx. 300

Geosynchronous orbits are at an altitude of 40 thousand km.\n\n An observer in such an orbit will observe as follows. \n\nIf he makes one revolution per day (earth time) in his orbit around the earth in the direction of earth’s rotation, the earth will exhibit always its one side.\n\nIf he makes one revolution per day in the opposite direction of earth’s rotation, the earth exhibits its entire surface to the observer by rotating itself twice per day. Similarly, we on the Earth will view the observer two times for a period of 0.25 day moving from East to West.\n\n If he makes one revolution per day in the same direction of earth’s rotation, the earth exhibits its entire surface to the observer by rotating itself twice per day but in a direction opposite to the previous one. Similarly, we on the Earth will view the observer two times for a period of 0.25 day moving from West to East.\n\n Instead of speed I am referring revolution per day because it is directly proportional to the revolution per day when the distance from the center of earth is fixed.\n\nIn the so called lower Earth orbits (up to 1400 km) there are 8000 satellites which are about 10 cm long   orbiting now around our earth with various speed and various directions. Some of them revolve the earth once in one hour.\n\nI am answering for unasked questions because just to reveal the fact that there are objects revolving around our earth with various speeds (more than the earth’s rotational speed) in various directions.

It depends on which satellite. TV satellites are in a geo-synchronous orbit, they remain over the same location all of the time.\n\nMost artificial satellites are placed in Low Earth Orbit (LEO), where they travel at about 27,400 km/h (8 km/s), making one revolution in about 90 minutes. The primary exception are communication satellites that require geostationary orbit. However, it requires less energy to place a satellite into a LEO and the satellite needs less powerful transmitters for data transfer, so LEO is still used for many communication applications. Because these orbits are not geostationary, a network of satellites is required to provide continuous coverage. Lower orbits also aid remote sensing satellites because of the added detail that can be gained. Remote sensing satellites can also take advantage of sun synchronous LEO orbits at an altitude of about 800km and near polar inclination. ENVISAT is one example of an earth observation satellite that makes use of this special type of LEO.

The EIDE  interface is rated at 133 MB per second while the SATA interface is rated for 150 MB per second. The second generation of SATA (SATA II) is rated for 300 MB per second.\n\nThe physical difference is the usage of a smaller cable that allows for easier routing in the case and better air flow. The logical difference is the speed with which the hard drive can talk to the rest of the computer.\n\nhttp://www.techweb.com/encyclopedia/defineterm.jhtml?term=IDE

Do you mean Global Terrestrial Observing System (GTOS)?\n\nObserving systems are programs that typically monitor environmental changes in the Earth.  Particularly, GTOS is a program for observations, modelling, and analysis of terrestrial ecosystems to support sustainable development.\n\nThere are a number of other programs such as Global Ocean Observing System (GOOS) for physical, chemical and biological measurements; Global Atmosphere Watch (GAW) for atmospheric constituent observing systems, etc.

Picture a weight on a string that you spin overhead. The shorter the string, the faster you have to spin the weight to keep it horizontal. It's the same with an orbiting body. A geostationary satellite is placed at the proper orbital radius that its rotational velocity is the same as that of the Earth, so it remains placed over the same spot on the globe as it speeds forward in its orbit.

Because most satellites are geosychronous (ie. Follow the earths rotation) a satellite dish can receive and transmit signals just as a you can receive satellite TV. This information is (should be at least) encrypted or scrambled so that only the person/organisation with the key or password can communicate with the satellite. The US have however failed to use this in the past several times and military satellite signals have been known to be able to be received by ordinary citizens given they point their dish in the right position.\n\nFor satellites that are not geosynchronous, ie. imaging satellites that work in a vertical plane such as the ones used by NASA to take pictures of the earth and spy satellites. These satellites are not in constant contact with land - they store their information and then relay it back in the short period of time it is in contact with the base station on earth.\n\nSatellites such as ones that visit Mars and that do not orbit the Earth simply use a higher output signal and a higher gain to receive signals. A larger satellite dish is required to receive these signals, and like the imaging satellites, they are usually not always in contact with earth.\n\nCheers

gis- geographical iformatioin systems\ngps- geographical positioning system.\nthe later has something to do with planning while gps is a garget that is more of a complex campus as it will tell you where ur basing on the 12 seterlites in orbit. you could google them to understand more.

When a satelite is launched, it is put in a eliptical orbit.  Depending upon the country which launches, then it is pushed to a particular geo-static position to meet the requirements of that country.  In the geo-static position, it would appear as if it is not moving since earth also moves along the same path.

It has to be at the equator.  It is the same reason that geostationary satellites are in orbit over the equator ...they always remain in the same position over the same spot of the Earth.

The orbit is called geosynchronous.  Check out the NASA website.  Your can see all the satellites we human have put into orbit.  It'll shock you!

A radio relay station in orbit above the earth that receives, amplifies and redirects analog and digital signals contained within a carrier frequency. There are three kinds. Geostationary (GEO) satellites are in orbit 22,282 miles above the earth and rotate with the earth, thus appearing stationary. The downlink from GEOs back to earth can be localized into small areas or cover as much as a third of the earth's surface.\n\nLow-earth orbit (LEO) satellites reside no more than 1,000 miles above the earth and revolve around the globe every couple of hours. They are only in view for a few minutes, and multiple LEOs are required to maintain continuous coverage. Medium-earth orbit (MEO) satellites are in the middle, taking about six hours to orbit the earth and in view for a couple of hours.\n\nI hope this helps...\n\nDon

Extremely doubtful.  The best resolution for US spy satellites has been guessed to be about 2 inches, which is much larger than the numbers on a license plate.  Even if it could resolve that small, the viewing angle would make it difficult to see the plate.\n\nAnyway, spy satellites circle the Earth at altitudes of about 150-200 miles, they aren't in geostationary orbit, which is around 22,000 miles.  At that distance, they'd be lucky to distinguish large buildings.\n\nEdit: A Guy, the GPS satellites are not in geostationary orbit.  They orbit at around 12,000 miles, which is about half geostationary distance.  The orbits are designed such that there are almost always 4 satellites in view from any point on the surface, since you need 4 for complete 3-D positioning.\n\nGeostationary orbit is used mostly for communications satellites, and some large-area weather overview satellites.  We do have some military satellites up there that watch for missile launches and any other large heat events, because they can be seen from that distance.  At that height, they can cover a good chunk of a hemisphere.\n\nHaysoos, stop being so paranoid.  They can't read your paper.

They usually have higher spindle speed, have more cache, are rated for higher MTBF (Mean time before failure).\n\nAlso, usually, the disk I/O is handled and offloaded to the SCSI controller.  This keeps the CPU more resources for other things.\n\nSCSI has higher transfer speed.  SCSI is capable of up to 360MBps and you can daisy chain more than 2 devices per channel.  Also, SCSI devices can be external devices.\n\nAlso, SATA's NCQ (native command queing) was not avilable to other ATA drives but was originally used on SCSI devices.

Satellites are generally boosted into orbit using rockets (although several have been deployed from the payload bay of the space shuttle).  Satellites have any number of functions.  Some relay telephone and data traffic from one place on earth to another.  Others do the same for TV signals.  Others (working together) form the backbone of the Global Positioning Satellite system (GPS).  Still others take pictures of the earth for various purposes.\n\nHope that helps.
