1 National Law Enforcement and Corrections Technology Center Communications Technologies Precision Indoor Personnel Location and Tracking for Emergency Responders Technology Workshop, August 4-6, 2008 Worcester Polytechnic Institute Odeum, Campus Center Worcester, MA Peter Small NLECTC Communications Technologies Dr. Alan Kaplan Drakontas LLC

2 Overview A program of the US Department of Justice, Office of Justice Programs National Institute of Justice (NIJ) administered by Drakontas, LLC. The Communications Technologies COE supports test and evaluation activities within the NIJ Communications Technology (CommTech) Program Introduction Personnel Location Problem: Law enforcement and corrections is inherently dangerous thus there is a need to determine the location and status of personnel. Focus Areas Personnel Location / Tracking Interoperable Voice Communications Convergent Data Services Wireless technologies (700MHz, 802.X) Communications Technology Tools Cell phone detect; alternative power Desired Outcome: A device which can be worn by a person that can track their location outdoors and indoors inclusive of elevation. Person - first responder, corrections officer, convicted offender sentenced to community based corrections, probation or parole.

3 Application A Reference Model for Personnel Location What to do with position location data? Who What Presentation Security/ Accountability Computation How to compute position location data GNSS Inertial Guidance Opportunistic Hybrid Local Network How to distribute position location data Licensed Fixed Infrastructure Unlicensed Ad hoc Mobility

4 Challenges: Heterogeneity and Interoperability Software-Defined Radio for GNSS Position / Location Middleware GPS Galileo GLONASS Applications Directory Services SOA Middleware Standard Radio front-end ADC Local Radio GNSS Hybrid Positioning Software Hardware

5 Pilot Process CommTech Technology Working Group Technologies selected for test and evaluation must meet one of the requirements as defined by the TWG. The TWG is comprised a group of law enforcement and corrections practitioners from across the US Technology Provider Participation Researchers and manufacturers provide equipment and services to support pilot deployment of their technology Pilot Site Selection Agencies are selected in cooperation with the NIJ CommTech Program Manager, that: are representative of the operational / technology problem can supply man power resources possesses sufficient infrastructure to support the pilot Test and Evaluation Process Adoption of NASA/DoD Technology Readiness Levels (TRL) Common Process Model Concepts of Operations Use of Operational Scenarios

6 Test & Evaluation Relevant TRL for T&E For individual Tech Components, NLECTC Communications Technologies COE is testing TRL For Systems, NLECTC Communications Technologies COE is testing TRL Common Process Model Descriptive - Track what actually happens during a test & evaluation process Prescriptive - Defines the desired processes and how they should/could/might be performed Explanatory - Provide explanations about the rationale of processes. Explore and evaluate various courses of action based on rational arguments. Concepts of Operations Standardized set of con-ops: With rigorous and reasonably complete specs (# users, mobility models, duration, etc.) With specific goals/objectives derived from the process model Each goal/objective with a specific set of test questions or evaluation hypotheses Define Comprehensive Metrics Given a specific con-ops, how to determine the effectiveness and performance of a given technology How well does it do? Is it optimal? How far off? How much does it cost (time, power, bandwidth, etc)?

7 Los Angeles County Sheriff s Dept. Pilot Objective: Test and evaluate location technology in an operational law enforcement environment as a survival tool - Precisely locate a deputy in need of assistance Concepts of Operation: Integration Operation (i.e., does it work?) Effectiveness and Accuracy (i.e., how well does it work?) Emergency Trigger Activation (i.e., does it help performance?) - Execute a scripted scenario Law Enforcement Impact: Further the understanding of the problem, refine current requirements and identify new requirements Operational Evaluation using scientific methods not just qualitative Assess the impact on LASD operations in terms of Officer Safety
