Background
• Recorded data for workload evaluation purposes.> Video data
> Audio data
> Soldier Machine Interface (SMI) (i.e. button pushes, WCA, etc) data
• Multiple VHS tapes for video and audio.
• Multiple computer configuration files for SMI and WCA data
• No timestamp synchronization between video/audio and other data
• Difficult to correlate and evaluate workload.
Multiple COTS VHS recorders mounted in a shock proof case

Current Approach
• TARDEC and Smiths Aerospace working solution via CARDA
Smiths provided• Army Video Solid-state Recorder
(AVSR)> Airborne Video Receptacle (AVR)
> Advanced Data Transfer Cartridge (ADTC)
• Operation Debrief System (ODS) software
• Micro Cartridge Interface Device (MicroCID)
• Engineering support
TARDEC provided:
• Crew integration and Automation Testbed (CAT) vehicle
• Test site> McGregor and Shorad Ranges, Fort Bliss,
TX
• Test subjects> Soldiers from Engineering & Analysis
Battle Lab, Ft. Knox, KY
• Integration activities
6/11/2003 5
• CAT vehicle is an Interim Armored Vehicle (IAV) Infantry Carrier Variant (ICV) or Stryker. > CAT is a multi-mission capable system: Fight, Scout, Carrier, and Unmanned
Asset Coordination
> The CAT has 2 identical advanced-technology crewstations.
> Embedded Simulation System (ESS) that provides crew with embedded training and embedded mission rehearsal
CAT Description

AVSR Description
• AVSR design based on Smiths product used in the F-22 program
• AVSR consists of:> Airborne Video Receptacle (AVR)
• 2 - audio input channels
• 4 - RS-170 NTSC video input channels
> Removable Advanced Data Transfer Cartridge (ADTC) • Provides up to 30 Gbyte of data storage
> Micro Cartridge Interface Device (MicroCID)• Allows ADTC to appear as a SCSI device to a computer
> Operational Debrief System (ODS) Software• Companion product to the AVSR
• Playback of up to eight video and two audio channels from one to four ADTC’s.
MicroCID ADTC

AVSR/CAT Integration
• AVR is the main interface between CAT and AVSR> AVR connections are hard wired to the CAT (shown on following chart)
> 2 video channels per crewmember• Sony XC555 color camera mounted over the shoulder
• CAT video switcher feed linked to the task that the crewmember is performing.
> Controlled through a discrete control box• Recording state (standby or record)
• 3 status LED's (ready, recording, or full)
• Event flag button

AVSR/CAT Integration (Cont.)2 - Over-the-shoulder Crew Cameras
(Sony XC555) Video Inputs
2 - SMI Display of Interest Video Inputs (via CAT Video Switcher)
2 - Crew Audio Inputs (via CAT Intercom System)
Discrete Control Box
AVR Unit

Playback System
• System used for workload and EET analysis> ADTC was removed from the vehicle
> ADTC inserted into the MicroCID
> Data copied to playback computer
• Dell PowerEdge 2650 - ODS SW installed> SCSI connection to the MicroCID
> Interface to the display and sound system
• Dell PowerVault 220S - RAID for media storage device> Contained 11-110 GB hard drives (1.2 TB storage capacity)

VTI Testing - CAT
• Testing completed at Ft. Bliss, TX during Feb and March 03
• CAT Maneuver Demonstration> Ft. Knox soldiers were responsible for complete control of the CAT
• Driving, target acquisition and engagement, command and control
> Goal was to evaluate workload of a 2 man crew• Move, shoot, communicate, unmanned asset control
• Engineering and Evaluation Tests (EET's)> Conducted to measure CAT performance criteria
6/11/2003 11
VTI Support for FCS UCD
• FCS UCD - CAT operated as surrogate C2V> Ft. Knox soldiers served as ARV operators
> CAT safety driver served as the C2V driver
• UCD Maneuver Demonstration> Goal was to prove feasibility of 1:1 ratio of operator to ARV.
• Mission consisted of route reconnaissance using ARV’s
• ESS used to simulate robotic weapons, sensors and semi-automated forces
• UCD Live Fire Demonstration> Goal to demonstrate target acquisition/engagement using unmanned ARV’s
• COUGAR turret weapon system mounted
on the RF platform – Controlled from the CAT system
– Javelin long-range weapon
– 7.62mm machine gun.

Results
• Currently distributing data to the UCD and VTI team for evaluation> No substantial results available at this time
• Initial results show a substantial improvement over previous data collection efforts > Reduced number of items that need to be correlated
> Added ability to time stamp all of the data sets
6/11/2003 13
Lessons Learned
• Sony XC555 camera great for viewing the SMI screens> SMI screens visible
> Crew appeared dark• Need to compromise between the screen and crew visibility
• Confusion/errors - minimal impact> Not downloading the data from the ADTC
> Loss of ADTC formatting information
6/11/2003 14
Future Capabilities
• Addition of Ethernet interface to AVR> On-vehicle event flag marking
• SMI or event triggered
> Changing the recording/encoding rate
• ADTC for transferring pre-mission and post-mission data > This would allow the ADTC to become the primary vehicle storage device
> Enhance training through post-mission comparison of simulated and actual data
Pre-mission data could include: • Digital mapping/mission data• Embedded training data• Passwords• UTO• etc.
Post-mission data could include: • Vehicle state date• Sensor data• SMI data• ESS data• etc.
6/11/2003 15
Future Capabilities (Cont.)
• Post-mission debrief/recreation capability> Capability to view actual crew video/audio synchronized with simulation of
vehicle locations and battlefield events
• Live video feedback to command center> Currently limited amount of bandwidth exists
> Smiths' is developing a configurable compression scheme that would allow for arbitrating limited bandwidth available in traditional battlefield RF links
• Addition of overlay data> Current/mission time
> Vehicle location
> Information displayed for a specific field of view • Go/no-go terrain overlaid on the driving screen
6/11/2003 16
Conclusion
• Apparent that AVSR is very beneficial> Will significantly reduced the time required to analyze data
> Reduced the number of correlated items
• Use of the AVSR system can only increase > ADTC as the primary data storage device
• CRADA exists TARDEC's Vetronics Business Group and Smiths’ > Covers the AVSR system as well other activities.
> Catalyst for the enhancements to the AVSR
