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.

8
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.

9
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.

10
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

STAR SDR approach

• Software Defined Radio
• Wideband RF processing
• Either directly or in IF the SDR concept allows
  to cover wide spectrums through simple
  re-configuration
• Wide dynamic range AD conversion and processing
• Antenna processing capability (SDMA)
• RF/IF re-configurability
• Ability to adapt to various waveforms
• Re-configurable RF level architectures
• Frequency agility in Tx and Rx modes

STAR SDR approach

• RF TECHNICAL ISSUES
• SWR ARCHITECTURE
• RF reconfiguraility
• Rx anti - jamming and high dynamic range in
  several modes and frequency bands using
  reconfigurable filtering chains
• Tx spurious rejection in several modes and
  frequency bands using reconfigurable filtering
  chains
