STAR Objectives
The STAR project will study and validate a secure, scalable, Wideband UMTS/3GPP communication system including the avionics modem and necessary ground communication infrastructure for a future air traffic communication system (part of ATM) with provision for future extension through SDR reconfigurability at avionics level.
In order to limit the impact of yet another system to be rolled out in aircrafts, the STAR consortium will investigate the usability of a Software Defined Radio (SDR) approach (both for radio and modem parts). The Software Defined Radio (SDR) concept, which has not been applied to avionics equipments yet in Europe, is an innovative technological breakthrough that will for the first time allow to provide backward compatibility with legacy systems but also forward compatibility with future ones.
Within the frame of STAR project, this concept will be implemented on two very different waveforms : WCDMA, UMTS stack based, transmitting in RF frequency (new mode)
VHF legacy audio transmission (SDR to legacy)

STAR Objectives
Development of a secure, scalable, wideband ATM/ATC radio system Safety is provided by the security of the communication system which features are :
Privacy : only authorised parties can get the data (cyphering, coding) Authentication : UMTS provides for mutual mean to prove the identity of the message originator Data integrity : data cannot be altered without detection Non-repudiation : it can undeniably be proven that a message was sent
and availability brought by the scalable high capacity provided by UMTS
Development of a representative trial network permitting the set-up of an air-ground link by airborne equipment in Wideband communications mode For the wideband communications ground infrastructure of the STAR system it is
planned to modify the 3G UMTS/FDD base station hardware as a basis.

STAR Objectives
Research and development of a prototype multi-mode (SDR) avionics RF + baseband platform able to support both wideband communications and the existing legacy formats. Software Defined Radio (RF + modem) : STAR is aiming at proving the advantages
of a SDR concept for avionics ATM purposes regarding: 1. Modulations (legacy analogue voice and digital wideband 3GPP) 2. Frequencies (at VHF for voice and at RF frequency for Wideband CDMA)
showing the backward compatibility of this concept with legacy and forward compatibility with other standards.

STAR Objectives
Estimation of the capacity and QoS improvements offered by a wideband communications system with regards to 8.33 kHz and VDL-Mode2 systems. Capacity : UMTS (3GPP) is able of the highest capacity ever
achieved in cellular networks QoS: UMTS protocols are able to handle in real time both
voice and data services with a high and defined Quality of Service (QoS = availability, high rate, security, robustness..)
Validation and verification of a secure wideband communications system by 2008 in lab and flight trials. The validation of the ATM SDR concept will be done:
In lab trials emulating the complete system (airborne and ground equipment), using channel simulators, traffic load generation and jamming, at VHF for legacy analogue voice and digital wideband modulation and at RF frequency for CDMA waveforms
Through flight trials in order to confirm the lab tests results, at VHF for legacy analogue voice and at RF frequency for CDMA waveforms.

STAR Objectives
Preparatory standardisation & regulatory activities required for an effective wideband based ATM system deployment. Standardisation : Preparation of the necessary inputs for ICAO Regulation : preparation of the necessary inputs for the
EUROCONTROL spectrum management group and ETSI with regard to spectrum allocation activities at WRC2007
Promotion of the system and dissemination towards the relevant stakeholders ICAO regulatory bodies such as ACP Airline Electronic Engineering Committee (ARINC) Civil aviation companies : through our partner IATA ANSP – activities happening through DFS and NATS
