tsk tsk you don't read well
sabi ko kahit anong suprise attack ng NOKOR malalaman ng USA dahil not only they can counter any missile attack using GPS using target tracking they can observe the land as well kung saan nakaposition yung mga missiles nila or even can be used as reconnaissance
wala naman sinabi sa binigay mong news tsk tsk tsk to post ko
nasan na dyan kayang calculate yung radar system wala naman sinabi lang dyan mag-iinstal sila ng dalawang radar system one sa japan yung isa nasa hawaii for calibration nasan na yung latest radar na kayang mag-calculate tsk tsk
bago magbigay ng resources basahin mo muna para di mag-mukhang tanga
kaya sinasabi ko ang GPS e may target tracking halos ang mga projectiles and missiles ng america e gumagamit ng GPS kaya nga kahit sabi ko kahit anong suprise attack ng NOKOR malalaman yan ng USA using GPS kahit di paliparin ang mga missiles ng NOKOR malalaman pa din yan ng america base sa ground photos
well, i guess you are the one misinformed about the real use and capabilities of GPS. GPS or Global Positioning System uses various Satellites in orbit to calculate for the longitude and latitude of a module. this is how it works. given the current position of the satellites, a GPS module installed (say on a vehicle) listens to satellite signal and based on the satellite id and time difference of the "actual arrival" of signals to "know" the exact location. in short there should be a module installed in a particular vehicle for its location to be monitored. example na lang po ay yung mga provincial buses that outfits their units (buses) with GPS modules for them to be monitored as to their current location.
"What Is GPS Tracking?
Do you need to track someone or something? Consider GPS tracking, with a Global Positioning System.
Of course, you could follow the person or thing every hour of the day, or hire someone else it to do it. Unfortunately, those options can be quite tiring and expensive, respectively. And quite frankly, few of us have any time, money, or effort to spare.
GPS tracking is, without a doubt, one of the most effective ways to track a person or object. While you've likely heard of GPS, what exactly is it? GPS includes a network of satellites and receivers to pinpoint the exact location of objects and humans on Earth.
What is GPS?
How does GPS work? The essence of the system includes 24 satellites that rotate around the earth twice daily. The satellites are in six different orbits, and are positioned at a precise angle in relation to the equator. Interestingly, while most of the satellites are constantly active, some of them are in standby mode.
Besides being accurate, the GPS system is also reliable and consistent. It's reliable because it's unaffected by weather. And it's consistent because its grid reference system is the same one used throughout the world. A receiver collects information from applicable satellites based on its current location, and then translates that information into a three-dimensional grid that indicates a particular location on Earth. While GPS is the most popular and accurate system of its kind, Russia uses a similar system (GLONASS).
The GPS satellites send information to at least a couple of components on Earth that contain GPS equipment. These components then process the information and then pinpoint the exact location of objects and humans. Amazingly, the number of receivers that can receive transmissions from the GPS satellites is unlimited!
What information does this network of satellites provide? While typically this information always includes the latitude and longitude of the person or object, it also usually includes the altitude. And this data can be a location on or above the Earth's surface. Amazingly, a GPS receiver can locate its own location in one second.
The GPS satellites were launched within two decades (1974 to 1994), and are managed by the USA's Department of Defense. In fact, the system of satellites and receivers was originally created for the United States military. Current satellites are replaced whenever it is necessary.
What are the applications of GPS?
The decrease in GPS receiver operating costs has increased the usage of GPS. From hikers to drivers, and from fishermen to militaries, the GPS system has become increasingly popular for pinpointing the location of people and objects on Earth. For instance, the US military uses GPS to navigate cruise missiles to designated targets. These missiles function by constantly using the satellites to pinpoint its current location.
But while GPS was designed for the U.S. military, several other applications exist. For example, scientists use GPS to monitor the movement of ice sheets at the North Pole or South Pole.
How is GPS used for vehicles?
Today, one of the most popular uses of GPS tracking is for vehicles. In a more pedestrian application, automobile drivers use GPS to calculate the most effective route from Point A to Point B. This replaces big and bulky maps, which can be a pain-in-the-neck.
Besides being used to map out a route, GPS is also used to track stolen vehicles. The GPS components are unseen, which further helps to prevent theft. That's because potential thefts would be uncertain whether a vehicle contains a GPS tracking device. In the case that the vehicle is stolen, the GPS system emits a single that only police departments are able to trace.
In this Information Age that we live in, some of the most pertinent information can be where a person or an object is located. Thanks to GPS tracking, you can secure that information quickly and accurately!"
http://www.topspysecrets.com/gps-tracking.html in short, without any receiver installed in a vehicle, using a GPS will never give a vehicle's (without a GPS module installed) exact location.
if you are still in doubt about what i am telling you with regards GPS, you can go to CDR-king and ask for a GPS device. or better yet go to goodhand88.com and get their address and ask them about GPS. if you want you can buy whatever "pure GPS" system that you can find and ill give you my exact location in coordinates, then i'd drive away for maybe 10 mins, then you tell me where i am afterwards. if you can give me my exact location, id buy your "pure gps" from you times 100.
you are partly right, though, when you say US troops use GPS in "positioning" and navigating their troops since their vehicles are equipped with GPS which tells their "control" or tactical center if you may their exact location. even their ground troops have GPS modules in their gears their location can be known.
my point is without any module in whatever thing you are tracking, there is no way top track anything by just pure GPS alone.

likewise, radar uses a technology similar to how dolphins "sonic-hones" into a prey. dolphins sends a high pitch sounds and listens for a "bounce".
"How Radar Works
by Marshall Brain
Radar is something that is in use all around us, although it is normally invisible. Air traffic control uses radar to track planes both on the ground and in the air, and also to guide planes in for smooth landings. Police use radar to detect the speed of passing motorists. NASA uses radar to map the Earth and other planets, to track satellites and space debris and to help with things like docking and maneuvering. The military uses it to detect the enemy and to guide weapons.
Meteorologists use radar to track storms, hurricanes and tornadoes. You even see a form of radar at many grocery stores when the doors open automatically! Obviously, radar is an extremely useful technology.
When people use radar, they are usually trying to accomplish one of three things:
Detect the presence of an object at a distance - Usually the "something" is moving, like an airplane, but radar can also be used to detect stationary objects buried underground. In some cases, radar can identify an object as well; for example, it can identify the type of aircraft it has detected.
Detect the speed of an object - This is the reason why police use radar.
Map something - The space shuttle and orbiting satellites use something called Synthetic Aperture Radar to create detailed topographic maps of the surface of planets and moons.
All three of these activities can be accomplished using two things you may be familiar with from everyday life: echo and Doppler shift. These two concepts are easy to understand in the realm of sound because your ears hear echo and Doppler shift every day. Radar makes use of the same techniques using radio waves.
In this article, we'll uncover radar's secrets. Let's look at the sound version first, since you are already familiar with this concept."
http://www.howstuffworks.com/radar.htm fyi, although i did say that radar allows the defense capabilities of US to actually "compute" for the "target" of such missile launch (it is not included in the article i quoted - since the purpose of the article quoted was to tell you that a radar is used to track a missile launch), they still need to wait for the lauch to actually happen since they will be needing the speed and angle of such missile for them to "guess" its target.
kaya sinasabi ko ang GPS e may target tracking halos ang mga projectiles and missiles ng america e gumagamit ng GPS kaya nga kahit sabi ko kahit anong suprise attack ng NOKOR malalaman yan ng USA using GPS kahit di paliparin ang mga missiles ng NOKOR malalaman pa din yan ng america base sa ground photoslikewise, you were right when you said that most projectiles and missiles of america have GPS installed in them, hence they can track its current location even after deployment. tanga naman kasi pag nasa SILO pa lang tapos tratrack pa nila di ba? however, do you thing NoKor is doubt enough to outfit their missile with a GPS module and actually provide US with the monitoring module. my point is, unless a GPS module is installed in NoKors missiles and its monitoring module is given to US a GPS will do no good in monitoring a missile launch
for your perusal, im also providing you the type of GPS for furthering your knowledge if such topic.
http://gps.about.com/od/beforeyoubuy/tp/GPS_do_for_you.htmhttp://www.igage.com/mp/GPSAccuracy.htm if you are still not convinced, research on airports and radar. or radar and typhoon. kasi kung gps lang pala katapat ng "monitoring" of missiles, eh di pwede ring gamitin ang GPS for "flight control" of airports for monitoring incoming and outgoing flights. eh malayong mas mura ang GPS kaya dapat yun na lang ang ginamit natin. PAGASA actually purchased several DOPPLER radar for their advance detection of typhoons.
http://newsinfo.inquirer.net/186495/accurate-forecasts-seen-with-doppler-radar-system fyi ulit, i am a bit "learned" about such technologies since i was a part of a project before which involves the use of GPS, etc.
if you are still doubtful of what i am telling you, then i rest my case. it is really hard to open a door when there is no door at all.
