NAN National ANS Network General Authority of Civil Aviation Air Navigation Services Kingdom of Saudi Arabia National ANS Network NAN

Goals of Project Implementation of kingdom wide network to serve all ANS facilities Support ATM and ATC data and voice flows Form a single and robust communication infrastructure Provide redundancy for links and communication hardware Provide simplicity and scalability of addition of applications Monitoring communication facilities to identify faults

Present ANS Communication Individual links for each application Lack of redundancy at Hardware and link levels Addition of application requires new circuits and hardware Delay of lunching of applications due to unavailability of lines
