6/11/20032 Agenda Background Current Approach Hardware Used During Testing >Crew integration and Automation Testbed (CAT) Description >Army Video Solid-state Recorder (AVSR) Description >AVSR/CAT Integration >Playback System Testing Description Results Lessons Learned Future Capabilities Conclusion

6/11/20033 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

6/11/20034 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

6/11/20035 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

6/11/20036 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 ADTCs. MicroCIDADTC

6/11/20037 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

6/11/20038 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

6/11/20039 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 ODS SW installed >SCSI connection to the MicroCID >Interface to the display and sound system Dell PowerVault 220S - RAID for media storage device >Contained GB hard drives (1.2 TB storage capacity)

6/11/ 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/ 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 ARVs ESS used to simulate robotic weapons, sensors and semi-automated forces UCD Live Fire Demonstration >Goal to demonstrate target acquisition/engagement using unmanned ARVs COUGAR turret weapon system mounted on the RF platform –Controlled from the CAT system –Javelin long-range weapon –7.62mm machine gun.

6/11/ 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/ 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/ 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/ 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/ 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
