 | Geospatially enriched synthetic environments are needed for development and assessment of unmanned ground vehicle (UGV) performance to support sensor fusion and sense making. This work will address how the high-fidelity/resolution environment is achieved and integrated to inform simulations addressing critical questions. We will investigate a multi-resolution modeling capability to inform development of a high-fidelity synthetic environment (HFSE) testbed and to link to other models and simulations. This report will discuss ... |

| Our overall audit objective was to determine whether U.S. ground forces supporting Operation Iraqi Freedom received training necessary to meet operational requirements. Specifically, we determined whether requirements reflect the training necessary in the area of operation. This is the second in a series of reports addressing training for U.S. ground forces supporting Operation Iraqi Freedom. Combatant commanders are responsible for giving authoritative direction to subordinate commands and forces, while coordinating ... |

| This study was conducted to evaluate a prototype enhanced night vision goggle (ENVG) that combines thermal and image intensification (I2) capabilities. Two infantry squads acted as participants. Soldiers were trained to use the ENVG and they received familiarization training on a baseline I2 device (AN/PVS-14). The exercises included woodland individual movement techniques (IMT) course trials; military operations in urban terrain (MOUT) target detection trials; land navigation exercises; MOUT defensive and ... |

| This report is intended to provide a high-level view of the evolving changes in satellite navigation services. Satellite navigation dates back as one of the first space applications. The report provides a chronological review of the development of the Global Positioning System (GPS), its current state, changes affecting the transition to a future state, and speculation on what that future state may bring. A detailed discussion of satellite navigation accuracy, ... |

|
 | Soldiers who need to navigate using a visual display do not have their eyes and hands available for other tasks. This can be prevented by presenting navigation information on a tactile waist belt, which proved to be effective in a previous study. In the current study, soldiers' performance on navigation and target detection in night operations was compared for three different systems: the tactile navigation system (called the Personal Tactile ... |

| The U.S. Army has a need to provide an affordable navigation system to meet the multi-mission needs of the warfighter. Recent advances in Micro-Electro Mechanical System (MEMS) inertial instruments, Global Positioning System (GPS) receivers, GPS anti-jam technologies and state-of-the-art processing allow the development of a low-cost, GPS/INS-based Personal Navigation System (PNS) that will meet the expected power, size, weight, cost, and performance needs of the Ground Soldier System (formerly Future ... |

| This paper presents the work of several ongoing studies to determine the effectiveness of multiple small robotic vehicles for performing mine field clearance, and the related problem of clearing unexploded ordnance from areas of interest. Many issues are implied in this opening sentence. Not the least of these is knowing, out the many items cluttering a battlefield, which ones need to be cleared. There is the problem of transiting through ... |

|
| Military and security operations often require that participants move as quickly as possible, while avoiding harm. Humans judge how fast they can drive, how sharply they can turn and how hard they can brake, based on a subjective assessment of vehicle handling, which results from responsiveness to driving commands, ride quality, and prior experience in similar conditions. Vehicle handling is a product of the vehicle dynamics and the vehicle-terrain interaction. ... |

|
| This project focuses on cooperation in the context of coordinated control of distributed, autonomous agents and the collection and fusion of the sensor information that they retrieve. Central is the synthesis and analysis of high-performance, group-level properties from simple control laws at the individual agent-level. There are three main objectives: (1) to develop a theoretical paradigm for formalizing the concepts of a group, a team, and control of groups, with ... |

| This study compares the effects of a visual and a 3-dimensional auditory display on primary and secondary task performance, mood, and mental workload at incremental levels of sleep deprivation. It is based on a study conducted by the Army Research Laboratory, Cognitive Science Branch, Aberdeen, Maryland, from 12 Marines performing land navigational tasks in two helmet- mounted display (HMD) modes; visual and 3-dimensional auditory, for a 48 hour period.

Yusu Wang; Pankaj K. Agarwal; Sariel Har-Peled; DUKE UNIV DURHAM NC DEPT OF COMPUTER SCIENCE
|
| We describe a fast algorithm to speed up rendering of scenes for walkthroughs in urban environments. Our occlusion culling algorithm takes advantage of temporal coherence in image space. As such, occlusion calculation is performed online only when needed. This enables us to employ intelligent occluder-selection and culling algorithms. We do not preprocess visibility information or pre-select occluders. Therefore, we can update scenes dynamically at a little cost. The algorithm features ... |

|
| The extended hyperbolic model for interfaces developed by Gomez, Filz, and Ebeling (Technical Report ITL-99-1; Report 2) can model the response of interfaces subjected to complex stress paths that may include simultaneous changes in shear and normal stresses and unloading-reloading. These types of loading can occur at soil-structure interfaces of multi-anchored systems used in navigation projects. Therefore, it is possible that finite element analyses of multi-anchored systems can be performed ... |

| Spatial knowledge acquisition is an integral part of navigation related studies. With the improvement of technology, the researchers gained the capability of testing the spatial ability in a virtual world as well. However, little research has been conducted to understand whether VE performance can predict Real World performance or not and amongst the measures used what measures are most predictive. This thesis research addresses the ... |

|
| The role of Unmanned Aerial Vehicles (UAV) for modern military operations is expected to expand in the 21st Century, including increased deployment of UAVs from Navy ships at sea. Autonomous operation of UAVs from ships at sea requires the UAV to land on a moving ship using only passive sensors installed in the UAV. This thesis investigates the feasibility of using passive vision sensors installed ... |

|
| The Pedograph, M1, is useful for rough mapping and sketching and for land navigation by individual soldiers or small groups. More specifically, the Pedograph, M1, may be used effectively with aerial photography to aid in filling in obscured details and to determine scale and magnetic orientation. It is useful for plotting the course of roads, trails, and streams, and for the location of important landmarks in unfamiliar terrain for which ... |
