5 Types of Radio Navigation Systems

Radio navigation is a form of radio determination that involves using radio frequencies for estimating a specific position on the globe. Also referred to as radio-navigation, it is similar to radiolocation. The Radio Direction Finder (RDF) was the first ever radio navigation system to be invented. Find out about the different types of radio-navigation systems available on the market.

Global Positioning System (GPS)

It makes use of a cluster of 24 Medium Earth Orbit satellites for the transmission of accurate microwave signals. A GPS receiver is used by the system for finding out its location, time, speed and direction. Today, it is used for both civilian and military purposes. Civilians use it for vehicular navigation or as a surveying equipment or compass. In the military, it is used for navigation, target tracking, map creation and reconnaissance, missile and projectile guidance etc.

Differential GPS for radio navigation

It is actually an improvement over the conventional Global Positioning System (GPS) and makes use of interconnected but fixed reference stations based on the ground for obtaining accurate positions of points that are unknown otherwise. These points are related to specific types of points referred to as Survey Markers. Click here to got more info about hw car stereo work.


This is a satellite navigation system, which is radio-based, and was created by the erstwhile Soviet Union. At present, it is used by the Russian Space Forces under the directions and permission of the Russian government. It serves as an alternative to the Compass Navigation System of China and the Global Positioning System (GPS) of the USA. It also challenges the Galileo Positioning System that is soon to be developed by the EU.

Transponder Landing System (TLS)

It is used at airports in those areas where architectural limitations or rough terrain make it expensive or otherwise impossible to use Instrument Landing System (ILS). In such locations where ILS is generally unavailable, TLS can ensure a precision approach. In built-up zones, it is expensive to set up a complex antenna set and maintain the same. TLS offers a viable alternative. It is a top choice for facilitating radio navigation.

Distance measuring equipment (DME)

This refers to a radio navigation technology that is based on transponders, and determines

Slant range distance through UHF or VHF radio signal propagation delay. Although it resembles secondary radar, DME works in reverse. In the coming years, the operation of DME will go on to check autoradio and there is a potential for its expansion in Galileo, GPS and other space-based navigational systems as an alternate source of navigation.

A car stereo Ford handy and advanced

Imagine you drive a new car every day to reach your daily appointments? It is the impression that you will have by equipping your vehicle with a Ford radio.
The multimedia stations are generally suitable for all facilities in single or double DIN. In any case, the presence of the touch screen facilitates the use of the GPS for Ford post. This serves to monitor the DVD reader and the decoder to the TNT antenna. He recorded Visual captures the DVR camera and the video-recorder camera back. It also displays the GPS mapping and allows the activation of the handsfree in the Bluetooth.
