What 2 coordinates is the global positioning system based on?

The Global Positioning System (GPS) is based on trilateration, which requires a minimum of three satellite signals to determine a user's position in terms of latitude, longitude, and altitude. GPS uses time signals from at least four satellites to calculate accurate coordinates for a specific location.

What technologies are used in space?

Some technologies are solar panels, whcih collects power from the sun and uses it to power sattelites, space vehicles, etc. Others are space probes which probe space and explore it for humans, without risking any human lives. Another type of space technology are space shuttles, or airborn vehicles that travel through space, containing, usually, humans.

How do you get a space station into space?

Basically, they build the space station on the ground first, then they break it into parts small enough to fit in the shuttle, and reassemble it in space. They are still making improvements on the space station today.

Does the density of aluminum has something to do with its being one of the wonder metals of space age?

It is important for all the materials used in the production of all types of air crafts to have low density. Aluminium and titanium (and their alloys) are frequently preferred because they are low density metals.

Aluminium is certainly good for building cars and planes. Additionally it corrodes very quickly to form a layer of aluminum oxide on its outer surface that then prevents further corrosion, so it doesn't need painting. I'm not sure that qualifies it as a wonder metal. I really like memory alloys such as nitinol, that 'remember' the shape they have been annealed into - these metals have many wonderful uses from orthodontic wires to repairing arteries or working the flaps on stealth planes.

How can you get Nightmares?

These are particularly bad or frightening dreams that may be the result of the brain trying to make sense of many of its (maybe unconnected) observations and sounds it recorded during the day.

Rarely, certain foods may send unpleasant signals during normal sleep.

Dreams are perfectly normal and most folk have three or four episodes of dreaming each night. Co-evidenced by Rapid Eye Movement, REM; which if interrupted to a waking state, will result in a dream story being recalled.

What type of metal are computer wires made of?

I'm sorry but that is too general of a question to accurately answer. They can be made from copper or gold or many other metals. MOST general wiring is copper but contacts or some very specific connections are sometime made of gold. There are also some other rare metals used in specific applications but those are the most common.

Will there be a series 6 for cube world?

As of now, there is no official announcement or confirmation regarding a series 6 for Cube World. It is best to keep an eye on the developer's updates and announcements for any future news about new series or updates to the game.

What is a zoogyroscope?

It is very older type of movie projector. At very long back at the evaluation time of movie projection a number of still frames photographed continuously to record a motion was passed through this projector to reflect it on a screen to create an illusion of motion by persistence of vision.

How a scratch outside of an optical fiber might cause problems?

Fiber optics, using optical fiber, are specially designed to implement total internal reflection. A signal passed from one end of the fiber to the other end of the fiber is a single beam of light that repeatedly bounces off the edges of the fiber until it reaches it's destination. By scratching the outside of an optical fiber, this property can be disrupted causing the signal to be lost.

True or false when you come closer to a distant object with a telescope the rays become less parallel?

True. When you come closer to a distant object with a telescope, the rays of light entering the telescope become less parallel as the object appears closer, and the lens or mirror in the telescope needs to adjust the focal length to focus properly on the object.

When were weather satellites invented?

The first weather satellite was developed by a team of NASA scientists rather than a single person. It was launched on April 1, 1960 from Cape Canaveral, now known as Cape Kennedy.

What is used to make globe filaments?

The first successful light bulb filaments were made of carbon (from carbonized paper or bamboo). In 1902 the Siemens company developed a tantalum lamp filament. From 1898 to around 1905 osmium was also used as a lamp filament.

In 1906 the tungsten filament was introduced

Who invented open space technology?

Open Space Technology was developed by Harrison Owen in the 1980s. He created this approach to facilitate inclusive, self-organizing meetings and conferences that enable participants to address complex issues and opportunities.

What technology is used to explore the polar regions?

Polar regions

· Snow houses - protection, accessible building material

· Snow shoes - saves time and energy, prevention of sinking into snow, travel longer and further

· Snow sled - faster and more efficient travel and transporting, today search and rescue, easier and further hunting

· Clothing - maintaining body heat, move around there environment more, spend more time outdoors

· Sunglasses - protection from the sun, spend more time outdoors

· Oil lamps - provide heat and light, cooking food, more active in the dark

· Ice breaker boats - more access, more hunting, more human interactions

How does a rocket continue to accelerate after launch?

A rocket continues to accelerate after launch by continuously burning fuel in its engines, which generates thrust. As the rocket's mass decreases due to burning fuel, its acceleration increases per Newton's second law of motion, F=ma. This process allows the rocket to overcome Earth's gravitational pull and gain speed as it travels through the atmosphere and into space.

What are the three basic parts of a rocket?

The three basic parts of a rocket are the rocket engine, which provides thrust for liftoff, the propellant tanks, which store the fuel and oxidizer, and the payload, which is the cargo the rocket is carrying into space.

What is a star shaped symbol called in printing?

A star shaped symbol in printing is called an asterisk (*). It is commonly used to indicate footnotes, side notes, or as a symbol for multiplication in mathematical equations.

Why was it a challenge to hold the audience's attention in Elizabethan theaters?

s it a challenge to hold the audience's attention in Elizabethan theaters?

The visial and hearing wasnt to todays standards no microphones and different heights of people standing in front of one another.

What are the space crafts in space presently?

The only manned space craft is the international space station which is in earth orbit. There are countless earth-orbitting satellites, most of them are there for communication (telephones etc.). Notable artificial satellites are the Hubble Space Telescope and the Kepler Space Telescope.

The Lunar Reconnassance Orbiter takes super-high resolution images of the moon, perhaps in preparation for future manned missions. Also there is the Chinese Chang'e 2 probe.

As for other planets, we have the Venus Express orbiter around Venus and the MESSENGER spacecraft orbitting Mercury.

On Mars there is the 2001 Mars Odyssey orbiter, Mars Express, Mars Reconnaissance Orbiter and Mars Global surveyor.

In the asteroid belt there is the Dawn spacecraft and several others.

There are no spacecraft orbitting Jupiter, the last one being Galileo which was sent to burn up in the Jovian atmosphere so the erase the possibility of contaminating the moon Europa, which may have sub-surface oceans with life.

Saturn has one orbiter, the Cassini spacecraft which primarily studies Saturn's moons, particularly Titan and it dropped at landing probe called Huygens to it's surface in 2005.

No spacecraft orbit Uranus or Neptune, but the New Horizons probe is heading towards Pluto and will arive in 2015.

4 probes are beyond that, Pioneer 10, Pioneer 11, Voyager 1 and Voyager 2 which all observed the outer planets about 40 years ago.

There are also numerous spacecraft that orbit the sun, but all of the major ones have been listed here.

What happens if you don't put on a space suit or space helmet?

You will loose oxygen then explode Actually, you won't explode. Within a few seconds the change in pressure will cause the gasses in your blood to boil and form bubbles in your bloodstream and lungs. It then becomes a matter of whether you die from that or from flash freezing at the low temperatures in space.
