GPS Aircraft Tracking
GPS AIRCRAFT TRACKING INTRODUCTION GPS aircraft tracking is a means of tracking the position of an aircraft fitted with a satellite navigation device. By communication with navigation satellites, detailed real-time data on flight variables can be passed to a server on the ground.

Source: www.wikiwand.com NETWORKS The different kinds of telecommunication networks used are: 1. ACARS - a hybrid of the VHF, satellite and HF network 2. The transponder "Mode S" (ADS-B) network 3. Satellite networks (Globalstar, Inmarsat, IRIDIUM, Thuraya) 4. The GSM network Source: www.wikiwand.com EQUIPMENT Some devices are avionics components like ACARS and ADS-B. In these cases the receiving and transmitting antenna are usually located outside of the airframe.

They are typically placed inside of the airframe in a location where the GPS and communication satellites are directly visible to the device, for example through the cockpit window.

This can safely reduce airspace separation of aircraft. GPS aircraft tracking also enables airlines to track their fleet of aircraft over the ACARS system, and allows aircraft to be more easily located in the event of an accident.

Finally, GPS aircraft tracking permits a flight school to track a trainee pilot and debrief his/her flight path afterwards.

Rather than relying on an emergency locator transmitter to transmit upon impact, the next generation of emergency locating devices are active tracking devices that send position reports at regular time intervals.

If the unit stops transmitting upon impact, the historical transmissions will give the last known location of the aircraft, its speed, direction and altitude. Tracking as an alternative or complement to current technology has recently been encouraged by the Coroner in New Zealand. Source: www.wikiwand.com
