How are satellite images taken?
They are taken from a very high definition camera attached to a satellite in space.
How high should be the satellite to be a geostationary?
In order to appear motionless in the sky, the satellite must be in an orbit that is -- circular -- over the equator -- 22,400 miles above the surface
Are Google Maps done with a satellite?
Google Maps provides satellite and map views in addition to Street Views. The satellite view of Google Maps uses the same backend satellite imagery database used by Google Earth.The satellite imagery are typically from the GeoEye or DigitalGlobe owned satellites, and some of the imagery are actually aerial photos from aircraft using special high resolution cameras.
True or False An artificial satellite in a high orbit will slow down and lose altitude due to the pull of Earth's gravity?
False. Why would it slow down? There is no friction in a high orbit; a satellite can orbit indefinitely. Only in low orbits will satellites slow down and fall from orbit, and the cause is the friction of the extremely tenuous final traces of Earth's atmosphere.
What is the difference between a High Power telescope and a Reflecting telescope?
A Reflecting telescope has a lot of zooming technologies and the High Power telescope is highly powered.
Which vacuum based device is widely used as a power amplifier in satellite communication system?
The Traveling Wave Tube Amplifier (TWTA) is widely used as a power amplifier in satellite communication systems. It amplifies signals in the microwave frequency range and is capable of providing high power output with low noise and distortion. TWTA technology has been utilized for several decades in satellite communication due to its reliable performance and efficiency.
What is a tube amplifier best adapted for?
Tube amplifiers are suitable for amplifying guitars, high-power radio and UHF television transmission, audiophile stereo transmission, and satellite transponders (such as those used in GPS).
For satellite communication the frequency should be less than critical frequency?
For satllite communication the frequency should not be less than the critical frequency because in satellite communicaton high frequency is needed which is reflected by satellite but not by the ionosphere.
What class that we prefer to use in power amplifier?
Class C because of its high power gain.
What are the system applications of a class B amplifier?
Class B operated amplifier is used extensively for audio amplifiers that require high power outputs. Its also used as the driver and power amplifier stages of transmitters.
What is the best brand of power amplifiers?
Behringer Europower EPQ2000 Power Amplifier is one of the best power amplifier that has high-quality components and ensures long life. It has several features and variable controls.
Why Amplifier of class B has high theoretical efficiency of 78.5 percent?
The Class B amplifier is a push pull amplifier with 78.5% efficiency. The high efficiency is due to the absence of power consumption during idle time which simultaneously increases the efficiency.
Advantage and disadvantage of geosynchronous satellite orbit used for satellite communication?
Advantages; they always appear to be in the same spot in the sky, so you can focus your satellite dish antenna on them. Disadvantages; they are quite high, about 23,000 miles up. You need a fairly strong signal to hit them, and a handheld device often doesn't have enough power.
What is the definition of amplifier?
If you are speaking of the radio amplifier, it takes the low powered signals from the radio and increases them for output to the speakers. Amplifiers usually have some provision or internal programming for splitting the signal so lower frequencies go to subwoofer and midbass speakers while higher frequencies go to tweeters.
What is high frequency tuned amplifier?
High frequency amplifier is a device which is tuned by high frequency. Tuned means the overlapping of generated frequency with that amplifier.
Alpine amplifier wattage for MRV-F300 V12 duo B circuit used older amp?
This type of amplifier has 75W x 4, V12 High Power Amplifier, MOSFET Power Supply, Non-Fading Pre-Amp Output, and Bass Engine.
Can anyone suggest how can you choose amplifier and speakers?
you need to choose speakers according to the power supply of amplifier, so that the amplifier can wrok. Besides, to create good sound effect, you need to take your room area into consideration, if the room is small, amplifier and speakers with high power is not necessary. You can visit website of Unify company, they have many packages for amplifier and speakers, hope it can help somehow.
