In summary, NGVA provides Military Land Vehicle system builders with a secure, high bandwidth, networking standard for sub system integration using DDS.

Land platforms are typically in-service for many years and are subject to significant updates through life. Recent experience has shown however, there is a need to be able to update platforms quickly in order to address new threats and scenarios. The traditional approach to platform design with stand alone sub-systems often results in:

Integration conflicts

A proliferation of crew controls and displays

Power conflicts

Lack of exploitation of data

Lack of standardisation across the fleet

The GVA open implementation standard was developed to support cost effective integration of sub-systems on land platforms (electronically, electrically and physically). Through the MilVA group, the GVA initiative was adopted by European nations and has become NGVA.

The net effect is significantly higher cost of ownership through the life of the vehicle. In an attempt to improve this situation the UK pioneered the Generic Vehicle Architecture (GVA). This is an approach to platform design and integration based on established Systems Engineering principles that define a generic architecture.

The role of a military vehicle has evolved dramatically over the last few years. It is envisaged that near future missions will focus on the need for an agile platform that is rapidly deployable, mission configurable, highly survivable, and cost effective. The Generic Vehicle Architecture will provide the necessary enablers to a fully integrated platform where even future capabilities can also be incorporated with minimum integration effort. Standardization and international cooperation between allied nations (NATO and European Union (EU)) is seen as crucial to this vision. The key drivers for standardization and international cooperation realised through NATO Generic Vehicle Architecture (NGVA) are:

NATO GVA is an open standards based approach to the design and integration of multiple electronic sub-systems onto a military vehicle, which are controllable from a multifunction crew display and control unit. It has been based on the UK MOD GVA approach but NGVA strives to enhance and expand it.

The NGVA Community

The NGVA community consists of governmental, industry and academia representatives from key and smaller European countries. These include permanent reps from the UK, Germany, France, Czech Republic, Norway and Sweden. Additionally, reps from Spain, Greece, Italy, Austria and Israel intermittently attend the meetings.

The NGVA STANAG is developed by the MILVA Working Group (Military Vetronics Association, mandated by NATO Land Capability Group 2.

NGVA Benefits

Current military system implementation faces several drawbacks such as:

  • A lack of interoperability between components
  • Subsystems having either no or proprietary interfaces using a variety of standards and protocols
  • Poorly documented interfaces
  • Specific operator panels per sub-system.

NGVA however,

  • Mandates appropriate interface standards and design constraints for the vehicle platform electronic data and power infrastructure associated safety and verification & validation guidelines
  • Lowers the cost of long-term system maintenance. System upgrades are made easier because the data interfaces are fixed and therefor integration cost is minimised
  • Means that the vehicle manufacturer will have a greater choice of sub systems and therefore more cost options
  • Allows for further cost savings when extensible data is approved for use in the NGVA standard. This means NGVA system readers and writers can handle additional data types and data type order reorganisation.
