The GPS (Global Positioning System) or NAVSTAR-GPS is a global navigation satellite system (GNSS) that determines the entire world the position of an object, a person, vehicle or ship, with an accuracy up to centimeters (when using differential GPS); usually a few meters of accuracy. GPS tracking systems was developed, installed and currently operated by the Department of Defense United States.
GPS works through a network of 24 satellites orbiting the globe at 20,200 km, with synchronized paths to cover the entire surface of the Earth. When you want to determine the position, the receiver is used to automatically locate it at least three satellites in the network, which receives a signal indicating identification and clock hours each. Based on these signals, the device synchronizes the GPS clock and calculates the time it takes to get the signals to the computer, and thereby measure the distance to the satellite using triangulation (trilateration method versa), which is based to determine the distance of each satellite relative to the point of measurement. Knowing the distance is easily determined one’s position relative to the three satellites. Knowing well the coordinates or position of each of the signal they emit, we obtain the absolute position or actual coordinates of the measurement. Also extreme accuracy is achieved in the GPS clock, similar to that of atomic clocks carried on board each satellite. It is also available when it comes to GPS vehicle tracking.
The Soviet Union built a similar system called GLONASS, now managed by the Russian Federation. Currently the EU is developing its own satellite positioning system called Galileo. More about GPS tracking device
Without a clean interactive “tool” for control of global temperatures, we are relying upon the unstable nature of our environment to continue to mend itself, regardless of our abusive actions. In addition to our own actions, history has shown that nature often has global extinction events. There are many natural generators of greenhouse gases.

Nanotechnology: Giving a new dimension to Food Industry
INTRODUCTION:
A derivative of chemistry, engineering, and physics, and micro fabrication techniques, nanotechnology involves manipulating matter at the nanoscale level. It is responsible for determining not only that biological and nonbiological structures measuring less than 100 nm exist but al Continue reading »
NANOMEDICINE in present century is the potent output of nanotechnology. It could changes the path of doctors to treat various life threaten diseases. Nanomedicine could increases effectiveness and reduces side effects unlike the other painful therapy. The basic principles of this technique are based on targeted drug delivery using nanoparticles, proper diagnosis using sensors and micro electro mechanical system (MEMS) and to monitor in vivo bioch Continue reading »
