1 Distribution Statement “A” (Approved for Public Release, Distribution Unlimited) 10th Annual Technologies for Critical Incident Preparedness Conference & Exposition 2008 Personnel Location and Tracking: Needs, Requirements and Technologies DOD Perspectives Paul Olson, Chief Engineer, Battle Command Division CERDEC / C2D

2 Distribution Statement “A” (Approved for Public Release, Distribution Unlimited) Why Position Navigation Timing (PNT) ? Traditional Role of position information is for own platform pilotage. Evolving Role of position information is as a shared resource creating Situation Awareness. Automated position reporting provides a common blue force deployment picture, adds context to modern digital battlefield systems to enhance: –Maneuver and Maneuver Control –Logistics –Intel Data Fusion –Air Defense –Fire Support –Munitions Emplacement The accuracy and availability of position and motion information directly affects the future Army’s C2 and Operational effectiveness.

3 Distribution Statement “A” (Approved for Public Release, Distribution Unlimited) Urban - Areas of Operations Subterranean Shanty Financial District Urban Sprawl High Density Inner City Heavy Industry Light Industry Cultural Center Distribution Statement “A” (Approved for Public Release, Distribution Unlimited)

4 The Urban/Indoor GPS Problem… GPS signals are available, but become highly degraded in urban and indoor environments –Ordinary GPS technology performs poorly in urban areas, jungles, mountains, and caves –Urban blockages and indoor weak signals are problems for GPS navigation and for receiver satellite tracking. Multipath = Position Error Multipath = Position Error Blockage = No Service Blockage = No Service GPS on its Own Cannot Provide a Reliable Precision Navigation Solution

5 Distribution Statement “A” (Approved for Public Release, Distribution Unlimited) Urban and Indoor PNT, a Shift in Requirements Not Just a GPS Requirement Anymore, Rather, It’s a PNT Requirement We are seeing examples from our troops and commanders, having expectations that a PNT capability will follow them, wherever their mission takes them.

6 Distribution Statement “A” (Approved for Public Release, Distribution Unlimited) US Army User Requirements for PNT TRADOC PAM Force Operating Capabilities –FOC-03-01: Command and Control: (6) –FOC-05-01: Mounted/Dismounted Maneuver: –FOC-05-03: Operations in Urban and Complex Terrain: –FOC-06-01: NLOS Lethality: (13) (e) Operational Requirements Documents: –Operational Requirements Documents for the Future Combat Systems (FCS) –Land Warrior Capability Development Document (CDD) for Ground Soldier System, Block III Objective requirements can be summed up as “An Affordable Precise PNT Capability for All Environments/Conditions”

7 Distribution Statement “A” (Approved for Public Release, Distribution Unlimited) Alternative Technical Options to Improve PNT Robustness Increase power from GPS satellites Signal processing improvements RF Aiding: –Beacons/Pseudolites at the GPS Frequency –RF ranging/aiding systems (TOA, TDOA, RSS, SoOP) –Network aided navigation Sensor aiding: –Inertial Navigation Systems –Doppler Radar Sensor –Visually Aided Navigation

8 Distribution Statement “A” (Approved for Public Release, Distribution Unlimited) How Pos/Nav Sensors are Effected by Structures and the Environment Pos/Nav Sensor/SystemLimitations Due to Environments Global Positioning System (GPS)Signal penetration, multipath, interference High Sensitivity (HS) GPSSame as above. Inertial Measurement UnitsNo issues with respect to environments, (accuracy degrades with time) Dead Reckoning DevicesMagnetic disturbances (accuracy degrades with distance traveled) RF Ranging and Signals of Opportunity Signal penetration, multipath, interference, emissions Doppler Velocity Sensors (RF and Acoustic) Degradation with respect to absorption Optical/Video Sensors and Techniques (Visual Flow, SLAM) Requires visual observations (depending on technology, could be limited by darkness, smoke, etc.) Others?

16 Distribution Statement “A” (Approved for Public Release, Distribution Unlimited) Personnel Location and Tracking: Needs, Requirements and Technologies DOD Perspectives Positioning, Navigation and Timing (PNT) information is enormously important to the Warfighter, the Commander, and hence to all Command and Control. Size, Weight, Power and Cost have been traditionally the performance limiting factors in PNT equipment and continue to be as we integrate on the Soldier. Areas for Concentration: User Interfaces (Commander’s and Soldier’s) and the development of standardized metrics, instrumentation systems and test methodology for system evaluation CERDEC and associate DoD labs are undergoing efforts to overcome these limiting factors by employing: –Advanced MEMS IMUs –Software GPS Receivers –RF Ranging –Datalinks to Assist GPS Performance –Merging of Communication and Navigation Functions

17 Distribution Statement “A” (Approved for Public Release, Distribution Unlimited) Purpose: Develop affordable, reliable and accurate component and integration technology for Soldier and platforms position, orientation and movement information to support operations and training in urban and other complex environments. Products: Technology to determine dismounted Soldiers’ own platform position and to track other unit members to 1m for operations in urban and other complex environments where GPS signal reception may be degraded. CERDEC’s Assured Pos/Nav Technology Program Payoff: Enhanced Situational Awareness through highly accurate, continuously available positioning, velocity and timing information Enable Soldier –based Cooperative Engagements Improved Dismounted Soldier Navigation
