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
Multiple COTS VHS recorders mounted in a shock proof case 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.
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
CAT Description • 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
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
2 - Over-the-shoulder Crew Cameras (Sony XC555) Video Inputs 2 - Crew Audio Inputs (via CAT Intercom System) AVR Unit 2 - SMI Display of Interest Video Inputs (via CAT Video Switcher) Discrete Control Box AVSR/CAT Integration (Cont.)
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
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 ODS and AVSR Example Clip!
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
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.
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
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
