ELECTRONIC COMMUNICATIONS (EC) DEPARTMENT
The Electronics Communications Department (EC) of Directorate of Safety Electronics Engineering Services (DSEES) is responsible for the provision, installation and maintenance of Satellite communications Systems (SATCOM), VSATs, AFTN Message Switch Systems, AIS AUTOMATION systems, and other ancillary facilities such as UPS, Regulators etc.
A. The Satellite Communication (SATCOM)
This network consists of eight (8) earth stations installed in Kano, Lagos, Abuja, Port Harcourt, Ilorin, Jos, Sokoto and Maiduguri. Kano and Lagos constitute the hub stations while the other six stations are remote nodes. The network architecture is based on the concept of Point to Point (SCPC) and configured in star topology. The Nigerian Network is part of the AFI Regional infrastructure (AFISNET) which includes Ghana, Cameroon, Gabon, Central African Republic, Niger, Chad, Congo, Benin Republic and Senegal among others. The AFISNET is provided to ensure seamless operation and interoperability among the Air Navigation Service Providers (ANSPs) for the enhancement of Air Safety.
VSAT – The Very Small Aperture Terminal (VSAT) is small, simple and portable satellite earth station that can be deployed with ease. WUKARI is a VSAT remote node that is added to the existing SATCOM network for provision of extended range VHF coverage within the North East Sector of our Airspace.
Services that ride on the SATCOM Network include but not limited to;
B. AIS AUTOMATION NETWORK
The contract for this project was awarded by the Federal Government and executed by NAMA. It is designed and executed as replacement and/or expansion to the existing SATCOM Network. As christened AIS AUTOMATION PROJECT AAP), it is a network of 27 VSAT nodes of ND-SatCom based on Bandwidth (Bw) efficient SKYWAN MF-TDMA technology. The VSAT nodes are for 26 Airports across the country and NEMA Hqtrs in Abuja. To ensure that there is no single point of failure and to ensure system availability in excess of 99.999%, the network is designed to run on two different Satellites of ASTRUIUM NSS 12 located at Longitude 57° East and INTELSAT IS 14 located at 315° East to achieve full satellite redundancy.
Deliverables of the AIS AUTOMATION Project (AAP) include 54 VSATs for 26 Airports and NEMA HQ, ATS/DS HOTLINES, AFTN/AMHS Message Switch Systems in Kano and Lagos, AIS DATABASE at NAMA HQ fully populated by WGS 84 Survey digital data for purposes of AIS CHATTING and MAPPING.
The TOTAL VHF COVERAGE System is expected to ride on it with provision for Primary, Secondary and Backup Frequencies.
The project is domiciled in Electronic Communication department and is expected to be completed this year, 2014.
