TAGPS Transponder AGPS – EGNOS

Alessandro Barazzetti

In the recent years, we have helped in the expansion diffuison of light aviation, in particular that of very light aircraft (VLA) and sport aviation. This growth is mainly due to the lwo costs involved in flying and maintaining these airplanes. Lights aircraft that are available in assembly kits, as well as bureaucratic procedures and costs for training and obtaining the pilot licenses are small. A new movement in support of aeronautics has consequently generated a market demand. Small start-ups have been born, revitalizing a sector that has been untapped for years, in conjunction with multinational company strategies. Unfortunately, the increase in aircraft and their performance, along with the fast growth rate, and the limited experience of pilots has led to a decrease in security levels. It is therefore necessary to support secure flight condition, by technologically advanced solutions.

In order to obtain this result, GPSAeroborne is developing a system called TAGPS, able to support pilotes and air fields in situational awareness, collision avoidance and air traffic control. TAGPS, based on GPS/GALILEO/EGNOS satellite systems, will be reproduced on aircraft cockpit main air navigation instruments. These data will be sent to the other aircraft operation in the same area and to the airfield control base, by mean of a SRD (short range device) within the available radio band. The TAGPS system is composed of a flight segment and one on the ground. Aircraft will be able to exchange information on their mutual position and the system will generate a proximity alarm as well as visualize, with the moving map. The position of the other aircraft flying simultaneously.

At the same time, a ground station receives the same data and the TAGPS system visualizes the current positions and trajectories of the aircraft and provides a forecast of their next path (air traffic control).

This ground segment will be a portable air traffic control. TAGPS will be very useful during the approach and landing phase with low visibility conditions or during high intensity traffic; web integration is being studied. Moreover, operational data recording on the ground segment will constitute an optimal training tool. TAGPS can show and analyze maneuvers of the VLA. This remote black box can be helpful for ascertaining the cause of accidents.

The capacity of the system in terms of reception and transmission of the data is in the order of some km, which is compatible with the performance of VLA aircrafts.
