What is the difference between a POES satellite and a GOES satellite?
A GOES satellite stays seemingly motionless, hovering 35,800 km above the Earth's equator, while a POES satellite travels over multiple lines of longitude, moving around the Earth. POES is also closer to the Earth, at about 750 km above Earth.
Do all satellites orbit the same direction?
No, all satellites do not orbit Earth at the same altitude. An good overview of this can be found on http://www.idirect.net/Company/Satellite-Basics/How-Satellite-Works.aspx. This overview reviews Low Earth Orbit, Medium Earth Orbit and Geostationary Orbits.
What is the polar orbit used for and why?
A polar orbit is used for Earth observation satellites and weather satellites because it covers the entire surface of the Earth. It allows these satellites to pass over both the North and South Poles, providing global coverage of the planet.
What is a circumpolar satellite?
In astronomy, it is a word denoting a star that from a given observer's latitude does not go below the horizon. For instance, no matter what time of year it is, if I go out on a clear night in Britain I can always see the stars of the plough (big dipper), they are circumpolar. However I can only see Orion in winter, it is not circumpolar.
What are the 2 orbits of satellites?
Artificial and natural satellites. Artificial satellites are man-made satellites sent into space for a variety of different purposes e.g. taking pictures of the earth for scientific investigation Natural satellites are moons, which orbit planets and are not man-made.
Some satellites are put into an orbit around the earths poles what is this type of orbit called?
A satellite orbiting around the Earth's poles is in a polar orbit. This type of orbit allows the satellite to pass over different parts of the Earth as it rotates below. Polar orbits are often used for Earth observation and surveillance satellites.
What is a polar highly elliptical satellite used for?
It is used for communication plates where geostationary satellites can't reach, in polar areas. Russia uses elliptical satellites where the geostationary satellites can't reach.
What is a polar satellite State two uses of a polar satellite?
A polar satellite is a type of satellite that orbits the Earth in a north-south direction, passing over both poles. Two uses of polar satellites are weather forecasting, as they can provide global coverage of weather patterns, and environmental monitoring, such as tracking changes in ice caps and studying climate change.
What is the exact time taken by the polar satellite in one revolution of earth?
Polar satellites, orbiting over the polar region (first link), takes approximately 100 minutes to do one complete pass at 25-degrees Earth rotational difference, to map the full section.(second link)For other satellites, it can take 90 minutes just to re-position a satellite to cover a new region, and THEN begin mapping. But the polar satellites stay in a constant orbit.
Is IRS a polar satellite or equatorial satellite?
It is polar orbiting.
Angle of inclination of a line?
In the context of satellites, the inclination angle is the angle between the equator and the polar orbit. The polar satellite has high angle of 90 Deg and the Geo SAT has angle of 0 Deg
What is the difference between a POES satellite and a GOES satellite?
A GOES satellite stays seemingly motionless, hovering 35,800 km above the Earth's equator, while a POES satellite travels over multiple lines of longitude, moving around the Earth. POES is also closer to the Earth, at about 750 km above Earth.
What is polar satellite?
The Polar Satellite was the name for a NASA science spacecraft which was launched February 24, 1996, to observe the magnetosphere. Polar was in a 86 degree orbital inclination with an orbital period of roughly 17.5 hours. The Polar Mission Operations were terminated on April 28th, 2008. Any satellite with a 90 degree tilt is considered to have a "polar orbit", as it allows the satellite to view every latitude of the Earth including the north and south poles.
What is the name of the next rocket of India?
The most recent rocket launch of India occurred in February 2013. The Polar Satellite Launch vehicle launched, carrying seven satellites, with the purpose of launching new ocean SARAL satellites.
What are facts about satellites?
Satellites send information. They can also take pictures of different items. Also, Satellites can help stranded boaters as well. They can also relay signals, which is what makes satellite T.V. possible.
What are the strategic locations of satellites?
There are two special locations for satellites: * geostationary orbits * polar orbits For satellite communication, it is very convenient if one can align fixed ground antenna to point at the satellite. The only way to get a satellite to stay exactly in front of a fixed ground antenna is to put it in geostationary orbit -- an altitude of 35,786 km above sea level above the equator. Other than geostationary orbit, there are a few other orbits that hold a satellite approximately in front of a fixed ground antenna for several hours -- the Molniya orbit and the Tundra orbit. Satellites designed to take photos of Earth (weather satellites, spy satellites, etc.) are typically in a polar orbit. Sooner or later, a satellite in polar orbit will end up directly overhead any given point on Earth. Typically these satellites are in an orbit very roughly 1000 km above sea level (roughly 100 minute orbit), because higher orbits are more expensive, and orbits less than a few hundred km rapidly decay from air friction.
When was Polar Satellite Launch Vehicle created?
Polar Satellite Launch Vehicle was created in 1993.
