Introduction The Army has a growing need to conduct operations in urban and indoor environments. The Communications Electronic Research, Development and Engineering Center's (CERDEC) Command and Control Directorate (C2D) is pursuing several programs to develop positioning capabilities for dismounted Soldier operating in these environments. Examples: Militarized 3D Locator (M3DL) Radio Frequency Adaptive Technologies Integrated with Communications And Location (RADICAL)
The following are examples of tactics, techniques and procedures: Individual movement techniques. Battle drills. Weapon positioning in an urban area. Roadblock and vehicle search procedures. Dismounted and mounted urban navigation. Urban scanning techniques. Quick fire techniques. Assault fire techniques. Typical Military Missions Hasty urban firing positions. Prepared urban firing positions. US Army HQ, Training Circular 90-1, TRAINING FOR URBAN OPERATIONS

Militarized 3D Locator (M3DL)
M3DL Background M3DL builds on the Department of Homeland Security (DHS) * Advanced 3D Locator (A3DL) program A3DL addressed firefighters and first responders applications M3DL addresses Soldiers operating in urban environments M3DL designed for military applications Requires replacing commercial subsystems with military subsystems (e.g. GPS, military communications / RF ranging radios) Top level architecture is very similar to A3DL * For more information on DHS Location Tracking, Contact, PM, DHS S&T

RF Adaptive Technologies Integrated with Communications And Location (RADICAL)
RF ADaptive Technologies Integrated with Communications And Location (RADICAL) Purpose: Develop and demonstrate software that identifies available spectrum dynamically (RF-aware) for tactical communications and for position location in GPS-degraded environments Products: Software module that enables spectrum policy management for Dynamic Spectrum Access (DSA) enabled radios (e.g. PRC-148/152) Architecture to integrate and enhance DARPA Disruption Tolerant Networking (DTN) for future use in Army tactical networks such as WIN-T Software for position locating based on Net Assisted Navigation and RF Ranging techniques Payoff: Reliable message delivery in disruptive communications environment Provide position locating in GPS degraded environments 08-01-08
Goal: RADICAL Navigation Technologies Develop RF based software modules for integration into soldiers radio systems. - Capable of insertion with a wide variety of soldiers radio systems. - Minimal impact to the hardware configuration of the communications or navigation equipment. Activities: - Soldier Navigation Architecture Study (SNAS) - Network Assisted Navigation Software Development - RF Ranging Software Development - Test & Integration
RF Ranging Estimate range between soldiers based on the time of flight of the communications packets. Active RF Ranging Require transmit signals designated for ranging Require more the radio s resources More accurate Better control Passive RF Ranging. Range measurements take advantage of the existing communication signals passing between radios Require less resources. Less accurate Rigid Both methods are being examined for use in the RADICAL application.
Network Assisted Navigation Improve the performance of GPS based navigation systems by providing data via the radio network to the GPS receiver. Using radio network to share position and measurement data between nodes to improve the overall position accuracy.
FY 09 Soldier Navigation Architecture Study (SNAS) Objective: - Identify and rank candidate navigation architecture to support the transition of the RADICAL navigation technologies to fielded systems. - Design a navigation architecture over the Platoon of dismounted Soldiers that satisfies the individual Soldier position performance needs while optimizing the navigation system attributes. - Identify and address future position capabilities for the Soldier.
