NAVISAT ATM Mission & Services • Fixed Aeronautical Communication • Communication links between ground ATM facilities via satellite (VSAT) • Voice and Data Services • Mobile Aeronautical Communication • Communication links between Aircraft and Ground • Cockpit Services (Air Traffic Services, Airline Operational Communication) • Passenger Services : GSM telephony (phone, SMS), internet • Satellite Navigation Augmentation • Communication links between ground navigation system facilities (VSAT) • Broadcast of GNSS augmentation signal • Service Coverage : Africa and Middle East
FIXED COMMUNICATIONS MIDVSAT(Project) MAIN INTERNATIONAL VSAT NETWORKS (existing and under study) CAFSAT NAFISAT (Project) AFISNET SADC AFISNET
FIXED COMMUNICATIONS COMPLETENESS OF THE DATABASE International and national fixed links integrated in the database Only Internationalfixed links integrated in the database
MOBILE COMMUNICATIONS EVOLUTION OF VOICE SERVICES Numbers of VHF remote stations declared by countries in the questionnaires • Short-term trend is to extend VHF coverage by deploying remote VHF stations (Algeria, Egypt, ASECNA, etc.). • HF is still maintained in some areas, though it offers poor quality communications, as it is considered: • better than nothing outside VHF coverage areas, • cheap back-up to VHF in VHF coverage areas. • Provisions should however been considered for Satcom Voice services for non-routine COM in medium to long-term
SURVEILLANCE SCENARIOS COVERAGE IN 2010 Existing Radars Already planned Radar installation to be deployed before 2010 Additional new Radar installation to be deployed before 2010
RS-7 AE-1 RS-8 RS-6 RS-1 RS-5 RS-2 RS-3 RS-4 TRAFFIC FLOW Main Route Segments Addressed by Satellite
REVENUES FROM COCKPIT (MOBILE) COMMUNICATIONS DEFINITION OF HIGH REVENUES AREAS AND ROUTE SEGMENTS • Satellite-based ATS datalink services in AFI : • should be mainly used along routes segments • with medium/high traffic • and located in oceanic areas or in remote areas, where there are no or limited radar / VHF coverage • should include CPDLC and FIS services, plus ADS-C services where no radar/ADS-B deployment has been implemented or is planned • Satellite-based ATS datalink services in MID: • should be deployed and used all over Egypt and the Arabic peninsula, • should include only FIS and CPDLC services as the Radar coverage will be almost complete in this area • Satellite-based AOC services in AFI/MID: • are assumed to be used mainly over the routes segments and areas where Satellite-based ATSC services are provided and used

NAVISAT INFRASTRUCTURE • 3 orbital positions included in NAVISAT Filling (updated in 2005) with the following spectrum allocation • L band in the MSS for the provision of aeronautical safety communications • L band in RNSS in order to be part of the GNSS-1 • C band in the FSS for feeder links of the aeronautical mission and for traditional telecommunication services • Ku band in the FSS for traditional telecommunication services 17°E 20°E MSS : Mobile Satellite Service (up1626.5-1660.5/down1525-1559MHz) MS(R)S : Mobile Satellite Route Service (1646.5-1656.5/1545-1555MHz) RNSS : Radio Navigation Satellite Service (L1:1575.42MHz,L2:1227.5,L5:1176.45MHz) FSS : Fixed Satellite Service (C-band 3.4-4.2/5.8-6.7GHz Ku-band 10.9-12.7/13.7-14.5GHz) GNSS : Global Navigation Satellite System 36.5°E
NAVISAT COMPLEMENTARY MISSION • Two options consideredin the study • Baseline scenario • Core ATM Mission in L-band and partially using C/Ku capacity • Complementary telecom mission with capacity lease in C and Ku bands • ATM optimised scenario • Optimised spacecraft for ATM mission only in L and C bands

POSSIBLE STRUCTURE OF NAVISAT ENTITYFPI MODEL COMBINING EFFICIENTLY THE PUBLIC SERVICES AND PRIVATE MEANS • Funding Private Initiative (FPI) model : this model basically proposed to have the private sectors conducting a business implementation for the satisfaction of public services needs • Lesson learned from EGNOS and GALILEO model and story
Confident that satellite based systems will be a key piece of THE solution for Global Air Traffic Management Possible role of Military in this context … to be discussed Thanks for your attention
