Standard for ground vehicle mobility

Abstract : Mobility implementation in military models and simulations (M&S) currently is tailored primarily for specific models, leading to inconsistency between models. To assist decision-makers in analysis, acquisition, and training activities, it is necessary to provide and promote consistency among the models. The NATO Reference Mobility Model (NRMM), Version II, is the Army Battle Command, Simulation and Experimentation Directorate, standard for single vehicle ground movement representation. This report describes the development of an NRMM-based Standard Mobility (STNDMob) Application Programming Interface (API) as a means of readily achieving higher fidelity movement representation by incorporating terrain-limited speeds into M&S. As described in the report, the STNDMob API, Version 3, includes descriptions of two derivative models: the low-resolution (Level 1) and the medium-resolution (Level 2) capabilities of STNDMob within the tactical/entity fidelity. Each level of resolution has two degrees of fidelity. These levels of resolution are an implementation of the physical models for steady-state speed conditions. As a whole, STNDMob can be classified as a service module that provides vehicle speeds to a vehicle routing service/planner.
