	Radio navigation - Wikipedia, the free encyclopedia
		Radio navigation or radionavigation is the application of radio frequencies to determining a position on the Earth.
		By tuning in a radio station and then using a directional antenna to find the direction to the broadcasting antenna, radio sources replaced the stars and planets of celestial navigation with a system that could be used in all weather and times of day.
		Commercial AM radio stations can be used for this task due to their long range and high power, but strings of low-power radio beacons were also set up specifically for this task.

	Radio - Wikipedia, the free encyclopedia
		Radio waves are a form of electromagnetic radiation, created whenever a charged object (in normal radio transmission, an electron) accelerates with a frequency that lies in the radio frequency (RF) portion of the electromagnetic spectrum.
		Radio was used to pass on orders and communications between armies and navies on both sides in World War I; Germany used radio communications for diplomatic messages once its submarine cables were cut by the British.
		Radio remote control: Use of radio waves to transmit control data to a remote object as in some early forms of guided missile, some early TV remotes and a range of model boats, cars and aeroplanes.

	[10.0] Radio Navigation Systems (Site not responding. Last check: )
		However, the basic concept of using radio signals for navigation was not new, as radio direction finding had been developed before the war and was used extensively during the war.
		Most ground-based radio beacons transmitted a two or three letter identifier in Morse code on their transmitter frequency to identify themselves, and it is plausible but unclear that YE/YG used the same approach.
		It was unique among major radio navigation systems in that it was developed, implemented, and maintained by a commercial company through its lifetime, instead of a government organization.

		When the appropriate VOR frequency is entered into a navigation radio, the VOR indicator connected to that radio is used to find where the aircraft is relative to the VOR station.
		When the appropriate ILS frequency is entered into the navigation radio, the horizontal needle indicates where the aircraft is in relation to the glide slope.

		The dial is, of course, marked like that of a navigator's compass with the usual thirty-two points instead of with ordinary minutes and seconds.
		Imagine what a sensation it must be to be up in a Zeppelin high over an impenetrable cloud bank, the sky overhead obscured by the bulk of the gas bag, and for these reasons all the landmarks by which a man ordinarily locates himself obscured.

	AG RVS - Traditional Aviation Radio Navigation: An Introduction
		Then certain instruments were devised which could `home in' on a radio signal, that is, could indicate in which direction relative to the aircraft a given radio signal was coming from.
		The radio signal induces a current in the loop, as in a normal aerial, but this current is weaker or stronger depending on the orientation of the loop.
		VOR navigation is the major navigation technique throughout much of the world, and certainly in developed countries such as the U.S. and Western Europe.

	Radio Navigation
		The next part of the course will teach you how to use the radio navigation instruments, when we get into the air we can then fly in clouds or bad weather, and know where we are without seeing the ground.
		By learning to fly on instruments and radio navigate you could then guarantee to return unless the weather is really severe.
		The NDB is a ground base radio transmitter that transmits a signal in all directions thus given it its name.

		The FAA has the statutory authority to establish, operate, maintain air navigation facilities and to prescribe standards for the operation of any of these aids which are used for instrument flight in federally controlled airspace.
		At least one satellite, in addition to those required for navigation, must be in view for the receiver to perform the RAIM function; thus, RAIM needs a minimum of 5 satellites in view, or 4 satellites and a barometric altimeter (baro-aiding) to detect an integrity anomaly.
		GPS navigation must be integrated with other forms of electronic navigation (when possible), as well as pilotage and dead reckoning.

		Though LORAN and EUROFIX (wide area augmentation of GPS) is available in North West Europe, because there has been poor political direction as to sustaining its service beyond 2004, and due to limited availability of receivers, few use it and indeed most European users have opted for using a single service, GPS.
		Previously, most users of radio-navigation services used to be found within the professional maritime or aviation community, these users were taught that it was unwise to rely on a single radio-navigation service, and all radio-navigation service should be treated as "an aid to navigation" and the derived position information was to be treated with caution.
		These are as diverse as driving vehicles to navigating whilst walking and cycling.
