Commercial in Confidence4© NEXTEL AEROSPACE DEFENCE & SECURITY S.L., 2013.All Rights ReservedOur Vision: Future of M&S systems is on the networkBut Reality is Complex:* Different Standards for interoperability* Too many COTS hard to interoperate between them* Different Data & Voice Communications* Legacy Systems* Heterogeneous simulation ecosystems* Security Issues* Scaling-Up to Very Large Exercises
