Does someone know about a software to decode Elementary and Enhanced Mode S and Extended Squitter transmissions from the aircrafts ATC transponders on 1090 MHz?
Some background information:
The EUROCONTROL ATM 2000+ Strategy confirmed Enhanced Surveillance as essential to safely enable additional traffic growth. Therefore, in the face of continuing traffic growth, Mode S Enhanced Surveillance is planned for deployment in France, Germany and the United Kingdom. The foreseen mandate is March 2005, with a transition period until March 2007.
Enhanced Surveillance through the ground acquisition of specific aircraft parameters will enable the Controllers to increase their efficiency in tactically separating aircraft. The Controller's information is improved by providing actual aircraft derived data such as Magnetic Heading, Air Speed, Selected Altitude and Vertical Rate enabling to reduce the radio telephony (RT) workload and better assess the separation situations. Enhanced Surveillance enables Monitoring Tools and Safety Nets which work on actual data to be implemented or improved (MSAW, STCA) which in turn will allow safety levels to be maintained or improved despite the increase in traffic levels.
Mode S Enhanced Surveillance will entail the use of eight Downlink Aircraft Parameters (DAPs) for initial implementation and these are:
Downlink Aircraft Parameters
Track Angle Rate
True Track Angle
The implementation of Mode S Enhanced Surveillance will supports the following benefits:
The implementation of Mode S Enhanced Surveillance will supports the following operational improvements:
Automatic Provision of Airborne Derived Data to Enhance Ground Systems Functions including Surveillance
Use of Data Link to improve Efficiency of Communications
Use Aircraft Derived Data for Ground Based Safety Nets
Enhance ATC Decision Support by using Aircraft Derived Data
Maintain and improve the quality of surveillance
The safety benefits of Enhanced Surveillance accrue through the improvement of the Controller's situational awareness by:
Reduction in risk of communication error
Improvement of safety by provision of a more precise prediction of horizontal and vertical aircraft behaviour (i.e. monitoring of altitude changes and the execution of altitude clearances)
Improvement of safety in high density traffic areas through increased situational awareness
Reduction of both Controller and Aircrew workload
Reduction of voice channel occupancy
Improvement of the capacity of pre-regulation (e.g. sequencing) in terminal sectors
Reduction of the Controller workload by reducing uncertainty concerning expected behaviour of the aircraft
Improvement of efficiency by allowing for more anticipation in planning of traffic

Just think about how fun it would be to have a program which can decode this information and display it on our computer!
