FOLIO HEADER: AFI VSAT DEVELOPMENTS<br />

Towards an Integrated AFI<br />

Telecommunications Network<br />

The Limited Africa-Indian Ocean Regional Air Navigation Meeting of 1988 (LIM AFI RAN/1988)<br />

recommended feasibility studies on the use of very small aperture satellite terminals (VSAT)<br />

as a means to meet the requirement for efficient <strong>and</strong> reliable communications in the AFI<br />

Region. It also acknowledged the importance of the satellite communications project<br />

developed for <strong>Central</strong> <strong>and</strong> <strong>Western</strong> Africa.<br />

As reported here by Prosper Zo’o Minto’o (Nairobi) <strong>and</strong> Francois Salambanga (Dakar),<br />

<strong>ICAO</strong> AFI Regional <strong>Office</strong>rs for Communications, Navigation <strong>and</strong> Surveillance, a <strong>Joint</strong><br />

Meeting of AFI Aeronautical VSAT Network Managers was held in 2011 by Air Traffic<br />

<strong>and</strong> Navigation Services (ATNS) of South Africa to discuss key issues related to aero-<br />

nautical VSAT networks, including the development of a roadmap towards a modernized,<br />

interoperable, sustainable <strong>and</strong> integrated network.<br />

As a follow up to recommendations from the Limited<br />

Africa-Indian Ocean Regional Air Navigation Meeting<br />

of 1988 (LIM AFI RAN 1988), a VSAT project known<br />

as AEROSATEL was implemented in the early 1990s.<br />

AEROSATEL was later exp<strong>and</strong>ed to cover other <strong>Central</strong><br />

<strong>and</strong> <strong>Western</strong> <strong>African</strong> States, as well as Southern <strong>African</strong><br />

<strong>and</strong> Indian Ocean States, resulting in today’s AFI Satellite<br />

Telecommunications Network (AFISNET).<br />

A similar project was implemented in early 2000s by<br />

South <strong>African</strong> Development Community States (SADC<br />

VSAT/1). A new generation of this network (SADC VSAT/2)<br />

was launched in 2008 together with the inauguration of<br />

a new VSAT network designed for North-Eastern <strong>African</strong><br />

States. At the same time, an inter-regional network involving<br />

<strong>African</strong>, European <strong>and</strong> South American States (CAFSAT),<br />

was implemented to cater for communications requirements<br />

between South Atlantic Area Control Centres (ACCs).<br />

The existing AFI VSAT networks, having been developed<br />

by different groupings of States at different points in time,<br />

are characterized by a number of conceptual <strong>and</strong> technical<br />

similarities <strong>and</strong> dissimilarities.<br />

Working arrangements between these networks include<br />

administrative (supervision, cost recovery mechanism),<br />

technical (personnel, maintenance), <strong>and</strong> network<br />

management (monitoring <strong>and</strong> control) synergies.<br />

A supervisory committee has been established for<br />

each VSAT network to oversee their performance.<br />
