Any object that moves aroundrepparttar 109914 earth has an orbit. The orbit is defined by 3 factors. The first isrepparttar 109915 shape ofrepparttar 109916 orbit, which can be circular or elliptical. The second isrepparttar 109917 altitude ofrepparttar 109918 orbit. The altitude is constant for a circular orbit but changes constantly for an elliptical orbit. The third factor isrepparttar 109919 anglerepparttar 109920 orbit makes withrepparttar 109921 equator. An orbit that bringsrepparttar 109922 satellite overrepparttar 109923 poles or close to it has a large angle. An orbit that makesrepparttar 109924 satellite stay close torepparttar 109925 equator has a small angle.

Orbits depend onrepparttar 109926 missionrepparttar 109927 satellite was built for. The following orbits can be defined:

Low Earth Orbit

Satellites in low earth orbit (LEO) orbitrepparttar 109928 earth at altitudes of less than 2000 km (1242 miles). Satellites in LEO can get much clearer surveillance images and require much less power to transmit their data torepparttar 109929 earth.

Medium Earth Orbit

At an altitude of around 10.000 km (6.000 miles) a satellite is in medium earth orbit (MEO). This altitude balancesrepparttar 109930 advantages and disadvantages of LEO and GEO. MEO’s are used generally for navigational satellites and communications satellites.

Geostationary Orbit

A satellite in geostationary orbit orbitsrepparttar 109931 earth in exactly 1 day and is placed aboverepparttar 109932 equator. The angle withrepparttar 109933 equator is 0 degrees. As a resultrepparttar 109934 satellite seems to stand still as seen fromrepparttar 109935 earth. These satellites are used for communications and Satellite TV.

Polar Orbit

An orbit that goes over bothrepparttar 109936 North andrepparttar 109937 South Pole is called a Polar Orbit. The angle withrepparttar 109938 equator is 90 degrees. The advantage of these orbits is that they go overrepparttar 109939 poles. This may sound funny, but in reality most satellites never “see”repparttar 109940 poles. Most polar orbits are in LEO, but any altitude can be used for a polar orbit.

Polar orbits are used a lot by navigation satellites which have to provide navigational information all overrepparttar 109941 world, includingrepparttar 109942 poles.

Sun Synchronous Orbit

This is a very interesting type of orbit. Satellites in Sun Synchronous Orbit pass overrepparttar 109943 same locations on earth atrepparttar 109944 same time each day. Suppose a satellite in sun synchronous orbit passes over your house at 3 pm. The next timerepparttar 109945 satellite will pass over your house is 24 hours later atrepparttar 109946 same timerepparttar 109947 next day.



The Ministry?s Sound Agenda

Written by Chris Meehan


A snapshot ofrepparttar Ministry Of Sound: from its Elephant and Castle beginnings to becoming a world-brand.

Dance music in London has been synonymous with The Ministry of Sound since it opened its exceptionally hip doors, in 1991. It?s ability to attract vast shoals of loved-up dance-heads torepparttar 109910 shady shores of London?s Elephant and Castle isrepparttar 109911 stuff of corporate dreams. To this day, it still pulls in 5,000 clubbers every sweat-swamped weekend ? for full-on cranial and physical recreation, atrepparttar 109912 hands of a Richter scale-measuring sound system.

This, then, is a huge predatory beast with an instinctive understanding of club culture. And, kraken-like, it dominatesrepparttar 109913 lively seas ofrepparttar 109914 London club scene - asrepparttar 109915 undisputed tentacled daddy. Its grip onrepparttar 109916 market has allowed its dangly limbs to stretch into recording, clothing,repparttar 109917 media and various other lucrative Ministry spin-offs.

The Ministry?s four sub-labels: Sound of Ministry, Ride, FSUK manufacture a spectrum of dance music to feedrepparttar 109918 full breadth ofrepparttar 109919 global dance music market and its constituent segments. In tandem with this, its media operation has a nice syndication number onrepparttar 109920 go, these days, allowing 150 radio stations in 38 countries to galvanizerepparttar 109921 airways with pre-recorded Ministry output.

HQs in New York, Berlin, Sydney and London, of course, enhancerepparttar 109922 credibility ofrepparttar 109923 world-brand being consolidated here. And, market penetration on a planetary scale continues apace, mirroringrepparttar 109924 rise of club culture as a common currency among near and far-flung youth ? say from: Beijing to Reykjavik, Mexico City to Mumbai. Ministry bars and clubs look set to be surfacing in a town near you inrepparttar 109925 not too distant future. What remains to be seen, though, is whetherrepparttar 109926 quality ofrepparttar 109927 product will be compromised in any way, now thatrepparttar 109928 Ministry is clearly dealing in economies of scale.
