Variable Message Format (VMF) Training Bootcamp

Variable Message Format (VMF) Training Bootcamp is a 4-day training crash course style covering VMF message standard, VMF data protocol and use cases in tactical radios. Learn about fundamentals and advanced Tactical radios and Variable Message Format (VMF), a message standard using K-series messages and all about communication protocols that are transmission media independent. Variable Message Format (VMF) training course provides participants  with the necessary knowledge and skills to analyze, specify, design, implement, test, V&V and operate systems and nodes using the VMF protocol, VMF message standard  and the VMF operating environments. The VMF protocol is used to exchange information between multiple different tactical systems providing rich and flexible messaging context. Exchange of operational and tactical data such as: positions, trajectories, maps, navigation data, mission data, surveillance and intelligence between the connected systems and nodes over Tactical Data Links (TDL) such as Link-16.  VMF is  well suited for  communications bandwidth constrained situations when Combat  Net Radio (CNR) networks are deployed and used. VMF and the Joint Range Extension Applications Protocol (JREAP) enable the exchange of voice, mission and tactical data and imagery by connecting to a network of various participant nodes, platforms and units, both vertically and horizontally. Variable Message Format (VMF) TrainingVMF elements and flags include:

  • Field Presence Indicator (FPI)
  • Field Recurrence Indicator (FRI)
  • Group Presence Indicator (GPI)
  • Group Recurrence Indicator (GRI)
