What is One Semi-Automated Forces (OneSAF)
Objective System (OOS)?

• A composable, next generation CGF
• Represent a full range of operations, systems,
  and control processes (TTP)
• Entity up to brigade level
• Variable level of fidelity
• Supports multiple Army MS domain (ACR, RDA,
  TEMO) applications.

Software only
Automated Composable Extensible Interoperable
Platform Independent
HLA DIS Capable

• Field to
• RDECs and Battle Labs
• National Guard armories
• Reserve training centers
• All active-duty brigades
• and battalions
• All FCS platforms

Capable of replacing legacy entity-based
simulations BBS, OTB/ModSAF, CCTT/AVCATT SAF,
Janus, JCATS MOUT

OOS Conceptual Model Overview

• A well-conceived, consistent intermediate model
  eliminates many problems by providing a model of
  the battlespace usable by all participants
  (customer, domain expert, developer, and user).

OOS Medium Resolution Communications Physical
Model (1/3)

• Range/LOS Methodology
• Based on the inputs (below) to determine the
  communication between a transmitting station and
  multiple receivers.
• Using the same inputs, determine if a
  transmission is jammed between a transmitter and
  its potential receivers.

Inputs Transmitter location (x,y,z) Message
transmission frequency (MHz) Range to each
potential receiver (Km) Transmission power
(Watts) Receiver frequency (MHz) Line of Sight
(Y or N) Jammer location (x,y,z) Range from
jammer to receivers (Km) Jammer frequency (MHz)

Message not received
Successful message receipt is a function of
transmitter max range and Line-Of-Sight with
receiver.

Process Determine If a Transmission is Jammed
Jamming is a post-step performed after an
unjammed reception determination has been made.

Message jamming is a function of frequency,
range and LOS with receiver.

T4 identifies a minefield and places the location
and extent in local SA and broadcasts info on the
platoon network. The platoon leader places info
within the Unit SA.
