Case Study: JVB
The Joint Precision Strike Demonstration (JPSD) Project Office, working in
conjunction with numerous teammates and partners, initiated the Joint Virtual
Battlespace (JVB) program to provide the Army with Simulation-Based Acquisition
(SBA) capabilities to support acquisition decisions for Objective Force and
Future Combat System (FCS). The goal of the program is to provide the Army with
a set of Simulation & Modeling for Acquisition, Requirements and Training
(SMART) tools that will support full spectrum analysis of system designs and
operational concepts while reducing risk and reducing acquisition timelines.
JVB is designed to augment current Modeling & Simulation (M&S)
and assessment efforts and provide a cohesive architecture to support
applications of SMART. JVB is an architecture, not a model, designed to
integrate existing models into a
|
robust representation of Battlespace with the
highest fidelity digital terrain, dynamic environmental effects, and
physics-based modeling. The JVB architecture or framework allows integrated
models to pass data between themselves and share a common Battlespace. It
provides a flexible, robust toolbox for evaluation of concepts, technologies,
and proposals. Inserting concepts into the JVB M&S framework provides data
on the operational impact of system trades, concept strengths, tactics
techniques & procedures (TTPs), and Concepts of Operation (CONOPS) from
entity to Joint Task Force levels. It supports full spectrum analysis by
enabling assessments of FCS concepts from component through Force-on-Force
interactions with the Legacy Force and the Objective Force in Army and Joint
Environments. JVB will conduct end-to-end experiments at entity-level
resolution. The unique JVB architecture allows scenario event impacts to one
model to be observed in other models at different entity levels. Just as in a
real battle, the impact of events in one location can influence the activity in
another location.
As of 1 May 2003, Dynamic Animation Systems became the prime contractor for the JVB program.

JVBView
|
The JVBView application from Dynamic Animation Systems provides a 3-D
visualization of an ongoing scenario in the JVB federation. Set against a
terrain database rich in features, JVBView renders elements received either via
DIS PDUs or from designated objects and interactions via the HLA RTI, using DDM
techniques if desired. These elements include:
|
|
|
-
Entities: fully textured 3 levels of detail, with an optional label indicating
the bumper number and damage state
- Communications: lines of communication between entities, color-coded according
to type, sender and receiver
- Perceived state: spheres with embedded models that denote the acquisition level
and identified type; displays both friendly and hostile perceived states
- Sensor areas of interest: 3-D volume representing the sensor’s extents as well
as cones for UAV sensors
- Detections: either a highlighted ring around the detected entity, or a sphere at
the detected location
|
- Routes: a series of connected waypoints, either resting on the terrain or tracing
a path in the air
- Detonations: animated explosions occurring at the point of impact
- Smoke: clouds of smoke over destroyed entities
Additionally, JVBView has a special “rogue” mode where the user can create their own
FCS unit cell comprised of C2 vehicles, direct fire vehicles and ground sensor vehicles;
the user can directly control each vehicle of this rogue unit cell, with its entity state
updated to the RTI.
