ONDAS ELECTROMAGNETICAS Are those waves that do not need a medium to propagate. They include, among others, visible light and radio waves, television and telephone.. Electromagnetic waves are transverse, the directions of the electric and magnetic fields are perpendicular to the propagation.

ESPECTRO ELECTROMAGNETICO The Electromagnetic Spectrum is a set of waves ranging from the waves with longer waves such as radio, even those with shorter and Gamma rays, via radio waves, microwaves, infrared, visible light, ultraviolet light and X rays

ESPECTRO ELECTROMAGNETICO

The electromagnetic spectrum covers wavelengths varied. There are frequencies of 30 Hz and minors who are relevant to the study of certain nebulae. On the other hand are known frequencies close to 2.9 × 1027 Hz, which have been detected from astrophysical sources. Electromagnetic energy at a particular wavelength λ (in vacuum) has an associated frequency f and photon energy E. Therefore, the electromagnetic spectrum can be expressed equally in any of these terms. Listed in the following equations: Or what is the same Or what is the same Donde (velocidad de la luz) y es la constante de Planck,.velocidad de la luzconstante de Planck RANGOS DEL ESPECTRO ELECTROMAGNETICO

For their study, the electromagnetic spectrum is divided into segments or strips, although this division is incorrect. There are waves having a frequency, but several applications, so that some frequencies can sometimes be included in two ranges.

TIPOS DE SATELITES EARTH OBSERVATION SATELLITE GPS SATELLITE NAVIGATION SATELLITE ORBITAL STATION MIR SATELLITE COMMUNICATION

SATELITE OBSERVACION A TIERRA Also called remote sensing. They carry specialized sensors that collect atmospheric data and land surface. Are useful in various fields such as meteorology, oceanography, environmental studies, or mapping.

SATELITE DE NAVEGACION (GPS) They allow the precise location of any point on Earth. They are based on triangulation methods, this calls for receiving data from at least three satellites. Positioning systems GPS and Galileo are based on this type of satellite.

SATELITE ESTACION ORBITAL (MIR) Laboratories in orbit to facilitate the implementation of extensive research in microgravity conditions. The International Space Station is currently the only space station. Its predecessors, the SpaceLab, Salyut and Mir are no longer operational.

SATELITE DE COMUNICION They provide a link for telephone, television broadcasts, Internet or permanent radio contact with ships, planes, trains..

In radio, the ranks are abbreviated with their initials in English. are: RADIOFRECUENCIA

Note that the frequencies between 1 GHz and 300 GHz, are called microwaves. These frequencies cover part of the UHF range and the full range of SHF and EHF. These waves are used in many systems, such as multiple data communication devices, radar and microwave ovens. BANDAS DE FRECUENCIA DE MICROONDAS

ORBITA is the path an object makes around another while under the influence of a centripetal force as the gravitational force

SATELITE ARTIFICIAL is any object that orbits around another, called the principal. The satellites are spacecraft manufactured on Earth and sent in a launch vehicle, a type of rocket that sends a payload into space. The satellites can orbit around moons, comets, asteroids, planets, stars or even galaxies. After its useful life may be artificial satellites and space junk in orbit.

FRECUENCIAS DE OPERACIÓN SUBIDA Y BAJADA RISE: The main component in the upstream section satellite is the earth station transmitter. DOWN: An earth station receiver input includes a BPF, a LNA and an RF to IF converter. Again, the BPF limits the power of the LNA input noise.

GPS “GLOBAL POSSITIONAL SYSTEM” (SISTEMA DE POSICIONAMIENTO GLOBAL) "NAVSTAR GPS: a global navigation satellite system (GNSS) which determines the entire world the position of an object, a person, vehicle or shed, with accuracy to the centimeter. The differential GPS: It consists of a static GPS receiver placed at a fixed and known, from which all visible satellites monitor and measure the distances to each of them.

ANTENAS RECEPTORAS An antenna is a device designed for the purpose of transmitting or receiving electromagnetic waves into free space. A transmitting antenna transforms electromagnetic wave voltages, and a receiver performs the inverse function

COMO DIRECIONAR UNA ANTENA RECEPTORA 1. enciendaa GPS receiver when the message ALERT aparescan press EXIT, then wait until the receiver acquires cordenadad and altitude, this can be verified as in the upper right side of a screen "Satellite" aparescan 3D. 1.2 see that this insurance that the recipient already has its position and altitude, dirijace just where is the place where the antenna is placed. NOTE: Remember that the altitude of the GPS receiver tells you is the encounter is in GPS receiver, so if the antenna aa place a different altitude where the GPS receiver must consider such variation.

INTERNET SATELITAL satellite internet connection is a method of Internet connection used as a means of a satellite link.

INTERNET SATELITAL ESTADO ACTUAL EN COLOMBIA It recommended a system of access in places where not served by cable or telephone, as rural or remote areas

Approx satellites in orbit at this time, of which are approximate running, the others are considered trash space until they return to earth, there are some that take 150 years for reentry. CUANTOS SATELITES HAY ???
