GVA meaning in General ?

The Generic Vehicle Architecture (GVA) approach is the approach taken by the UK MOD to the design of the electronic and power architectures for military vehicles. It also includes requirements for standardisation of the Human Machine interface. The main requirements for this approach are published in Defence Standard 23-009

Land platforms are typically in-service for many years and are subject to significant updates through life. Recent experience has shown how 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 results in stove piped upgrades with integration conflicts, a proliferation of crew controls and displays, power conflicts, lack of exploitation of data and lack of standardisation across the fleet with training and maintenance issues. All these issues lead to a significantly higher cost of ownership through life.

The GVA approach is based on established Systems Engineering principles to define a generic architecture that requires open implementation standards to support cost effective integration of sub-systems on land platforms (electronically, electrically and physically). The Director Land Equipment (DLE) has mandated the application of the GVA Approach and the associated GVA Defence Standard 23-009 for all future land vehicle platform procurement, current vehicle platform refurbishment and upgrade programmes. GVA is an integral part of the Land Open System Architecture (LOSA) which aims to enable soldiers, vehicles, and bases to work better together thereby increasing operational effectiveness and reducing the systems of systems through life costs.

An integral part of LOSA and GVA is a data standard based on an Object Management Group (OMG) Standard called Model Driven Architecture (MDA). The data standard is called the Land Data Model (LDM) and defines data interfaces and behaviour between components of the modular architecture. This enables interoperability between modules built by different vendors for use in a distributed system. The LDM can be accessed at the Land Open Systems Portal.
