Radio SETI (Search for Extraterrestrial Intelligence) is the effort to detect narrow-band radio signals. Nothing known other than technology (i.e., a radio station) can make narrow-band signals—that is, signals that you can tune into and out of with just a turn or two of the radio dial. Optical SETI uses the same reasoning, but here again apparently only technology can produce light pulses that last a billionth (nano) of a second (although stars can collapse to make a millisecond pulsar that can pulse a thousand times per second). Since PlanetQuest will be using only the red part of the star’s light to detect the transits of planets across their stars, we plan to "beam-split" (divide off) the blue light and send it to our nano-second diode detectors to see at the same time if any of those stars are sending billionth-of-a-second pulses toward us, as well. Thus you, the PlanetQuester, will be looking for planets and extraterrestrial technology at the same time!

In the broadest sense, remote sensing is the measurement or acquisition of information of an object or phenomenon, by a recording device that is not in physical or intimate contact with the object. In practice, remote sensing is the utilization at a distance (as from aircraft, spacecraft, satellite, or ship) of any device for gathering information about the environment. Thus an aircraft taking photographs, Earth observation and Weather satellites, monitoring of a fetus in the womb via ultrasound, and space probes are all examples of remote sensing. In modern usage, the term generally refers to techniques involving the use of instruments aboard aircraft and spacecraft rather then other fields which are considered to be under medical imaging.

There are many different kinds of satellites that are used to help protect the security of the United States and our forces around the world.\n\nThe kind most people think of take pictures, providing imagery intelligence (IMINT).  These are used to do things like discover where a potential enemy may be building rockets that could be targeted at the US.  We can also use radar to take pictures of a sort - not as clear as visual pictures, but much more valuable over a cloudy area!\n\nEven though "a picture is worth 1000 words," it is still very very valuable for us to hear those 1000 words, so another kind of satellite can monitor some kinds of radio transmissions.  Imagine how valuable it might be to our forces if we've heard an enemy commander say "We attack the town at dawn."  This kind of intelligence is called COMINT.\n\nOther satellites monitor other kinds of electronic signals - SIGINT. And some view and report on other things, like the heat of a rocket launch, to provide measurement and signatures intelligence - MASINT.\n\nNone of these is known officially as a "spy satellite," so, technically, there is no official answer to your question.  But they all are used to get information on potentially dangerous countries and organizations that want to harm our country.  Since those bad actors probably would not like us to see what they're doing, it could all be called 'spying.'\n\nMaybe it's easier to define what's NOT a "spy satellite."  Satellites that are used for purposes that are not secret and support non-defense purposes include navigation, weather, and communications.  I don't think anyone would categorize any of  them as spy satellites.\n\nBoth our civilian intelligence agencies and the military employ quite a few people to perform the very important tasks of building, flying, collecting, and analyzing all the intelligence from these sources.  If you're patriotic and technically minded, it's a great career!

United States Strategic Command tracks objects orbiting earth.  An AN/FPS-85 phased array radar, located at Eglin Air Force Base, is the primary sensor used to track these objects.  The radar is capable of tracking objects the size of a soccer ball at 20,000 miles.  The quote following is from USSTRATCOM's website (see first link).  The second link provides additional information on the Eglin RADAR. \n\nFWIW, the Eglin RADAR is now receiving a major hardware and software upgrade under the SENSOR contract.  ITT is the prime contractor and Northrop Grumman is the major sub.\n\n"USSTRATCOM tracks about 8,500 man-made space objects, baseball-size and larger, orbiting Earth. The space objects consist of active/inactive satellites, spent rocket bodies, or fragmentation. About 7 percent are operational satellites, 15 percent are rocket bodies, and about 78 percent are fragmentation and inactive satellites."

It depends on which satellite. TV satellites are in a geo-synchronous orbit, they remain over the same location all of the time.\n\nMost artificial satellites are placed in Low Earth Orbit (LEO), where they travel at about 27,400 km/h (8 km/s), making one revolution in about 90 minutes. The primary exception are communication satellites that require geostationary orbit. However, it requires less energy to place a satellite into a LEO and the satellite needs less powerful transmitters for data transfer, so LEO is still used for many communication applications. Because these orbits are not geostationary, a network of satellites is required to provide continuous coverage. Lower orbits also aid remote sensing satellites because of the added detail that can be gained. Remote sensing satellites can also take advantage of sun synchronous LEO orbits at an altitude of about 800km and near polar inclination. ENVISAT is one example of an earth observation satellite that makes use of this special type of LEO.

Types of satellites? Well there are many ways of classifying satellites:\n\nStabilisation\nSatellites have to be stabilised so that they can always point in the direction they want to be pointed in and so that they can thrust in the right direction etc. You can have 3 axis stabilised or rotational stabilisation (where one bit spins, like the solar panels, and one bit is de-spun, like the dishes)\n\nFunction:\nMilitary, earth observation, solar observation, deep space exploration, communication (Satellite TV & cell phones) are some examples of different satellite functions\n\nOrbit:\nYou can have satellites in many different orbits. Near Earth Orbit, where it orbits at a low altitude (e.g. 200miles, time to complete 1 orbit = 90 minutes), Geostationary orbit (orbit period = 24 hours), Highly Eliptical orbit (for communications in high latitudes). Lagrange orbit (satellite stays in the same place relative to the sun&earth)\n\nYou can find out more on any of these with a simple google search on their names

Technology, general term for the processes by which human beings fashion tools and machines to increase their control and understanding of the material environment. The term is derived from the Greek words tekhnē, which refers to an art or craft, and logia, meaning an area of study; thus, technology means, literally, the study, or science, of crafting.\n\nMany historians of science argue not only that technology is an essential condition of advanced, industrial civilization but also that the rate of technological change has developed its own momentum in recent centuries. Innovations now seem to appear at a rate that increases geometrically, without respect to geographical limits or political systems. These innovations tend to transform traditional cultural systems, frequently with unexpected social consequences. Thus technology can be conceived as both a creative and a destructive process.

Information Technology (IT) or Information and Communication(s) Technology (ICT) is a broad subject concerned with technology and other aspects of managing and processing information, especially in large organizations.\n\nIn particular, IT deals with the use of electronic computers and computer software to convert, store, protect, process, transmit, and retrieve information. For that reason, computer professionals are often called IT specialists, and the division of a company or university that deals with software technology is often called the IT department. Other names for the latter are Information Services (IS) or Management Information Services (MIS).

Understanding physics has allowed us to launch satellites.  We also know how to make satellites transponders to transmit television signals and know how to calculate the footprint of the transmitted signal.  With world-wide satellite coverage, we never have to go to work.  We can drink beer and watch footy all day long.  Isn't physics great?!

Satellites are generally boosted into orbit using rockets (although several have been deployed from the payload bay of the space shuttle).  Satellites have any number of functions.  Some relay telephone and data traffic from one place on earth to another.  Others do the same for TV signals.  Others (working together) form the backbone of the Global Positioning Satellite system (GPS).  Still others take pictures of the earth for various purposes.\n\nHope that helps.

Usually with the use of the internet for everyday people\nand tv, radio forecasts, they collect data from airports\nand other observation facilities. At higher level with the use\nof satellites made for measuring the different radiations going\nout from the earth. They can measure heat, and the changes\nin the air like fog or rain.
