describe the effect that satellite has on society?

Answer 1

Satellites have affected society in numerous ways, benefitting communications, navigation and monitoring.

Communication has changed dramatically since the advent of satellites. The first geostationary satellites, first suggested by science fiction writer Arthur C. Clarke, helped created a link across the oceans by microwave. These satellites made it possible to call overseas. Satellites also revolutionized television. Television now comes in hundreds of different channels to the consumer, all made possible by satellite downlinks from geostationary satellites rather than the old way of carrying via tape or cables. Remote areas can now get internet service via satellite, whereas they could not get service before due to the high cost of cables. Many point-of-sale transaction points are connected by satellite. For example, gas stations often have small satellite dishes (called VSAT) to download the latest advertisements for the pump, complete credit card transactions and update the latest inventory levels. For people on boats, oil rigs and very remote areas, satellite phones are the only way to communicate to the outside world.

Satellites have also lead to a revolution in navigation. There is a swarm of low-earth-orbit satellites (LEO) that handle global positioning. Ships, which used to solely rely on radar, no longer fear the yawning expanses of the oceans. Drivers can see where they are (and where they are supposed to go) with their dash board GPS. Hikers can now get around without getting lost from their inaccurate compasses. Even bombs can find their targets more accurately with less collateral damage with GPS.

Satellites have also helped in monitoring. LEOs have revolutionized assay services - measuring large amounts. They allow us to monitor friendly assets as well as keep an eye out for unfriendly groups. They can help farmers optimize yields by measuring rainfall, runoff, fertilizer absorbtion and yields. They can show the big picture, where global warming is eating away ice shelves that nobody else can see.

Yes, these several ton hunks of metal with batteries that last only about 15 years are one of the few pieces of hardware that really affect our daily lives.

Answer 2

i've got theory approximately that as quickly as observing celeb Trek and you have Scotty together with his Scottish brogue, and the Russian Chekhov and the jap Sulu. And the yank Captain Kirk, by using fact the dominant lifestyle representation. could that quite be probably centuries from now? They are looking forward to redheads will disappear faster or later interior the destiny by using fact the recessive gene could be conquer via intermixing. it is real that folk of diverse ethnicities stay area-via-area plenty greater now, and on occasion, they are blending (interior the U.S. enormously plenty all with eu ancestry are of one lifestyle). yet real homogenizing could take an prolonged time. we've had interior of reach human beings, blacks and whites residing area-via-area interior the U.S. for greater desirable than 2 centuries, and on a similar time as there is a few blending between those bigger communities, we are nonetheless customarily voluntarily segregated in marriage and in lifestyle. some cultures are no longer very tolerant of one yet another, like the Gypsies in Europe, who're very distinctive from their pals inspite of much greater centuries of residing on the brink of one yet another. The Italians, French and British have been all area of the comparable Roman Empire, yet they retained their adjustments (altho the British did %. up quite some French impacts at particular factors). In Singapore you have a blend of Malays, chinese language, Indians and others at the same time in a cramped society, yet so far they are holding their identities. And after all, i think of top oil (perhaps greater suitable seen by using fact the tip of cheap oil) will positioned a great damper on globalization - no longer will or no longer that is greater cost-effective to catch crabs in Alaska, deliver them to Taiwan for processing, and deliver them back to Seattle to be bought in Chicago, or deliver cotton grown interior the southern states to China to be made into T-shirts bought in Walmarts around the U.S. yet back on your question, how are you able to've a dominant lifestyle if all cultures are a uniform blend?
