NASA Scientific and Technical Aerospace Reports

esult of a yearlong, campus-wide, integrated research systems engineering effort involving 40 student researchers and 15
supervising faculty members. This report (Volume 1) summaries the CROSSBOW project. It catalogs the major features of
each of the components, and includes by reference a separate volume for each of the major systems (ships, aircraft, and
logistics). It also presents the results of the mission and campaign analyses that informed the trade offs between these
components. It describes certain functions of CROSSBOW in detil through specialized supporting studies. The student work
presnted here is technologically feasible, integrated, and imaginative. This student project cannot by itslef provide definitive
designs for analyses covering such a broad topic. It does strongly suggest that the underlying concepts have merit and deserve
further serious study by the Navy as it transforms itself.

Deployable Combat Simulation Via Wireless Architectures

This thesis details the critical need for deployable combat simulations for training in today’s surge force environment. To
truly realize deployment of these simulations on Naval vessels and in remote theaters, simulations for training must be
wireless. Wireless standards 8O2.ll/a/b/g are presented in detail to highlight the strengths and weaknesses of each. This thesis
then investigates the viability of deploying combat simulations for training using wireless devices. To this end, the Joint Semi-
Automated Forces (JSAF), combat simulation model and the Virtual Helicopter (VEHELO) training simulation entity are
tested in an 8O2.lla wireless environment against the VEHELO application in a wired environment. 8O2.lla is proposed as
part of an overall solution to deploy combat simulations for training. This is primarily because of its high data rates and ability
to co-locate access points without interference. Testing reveals that operating JEAF and Virtual Helicopter via the High Level
Architecture (HLA) with User Datagram Protocol (UDP) packets in an 8O2.lla environment provides ample bandwidth with
which to deploy combat simulation for training for the simulations conducted.

Applications for Mini VTOL UAV for Law Enforcement

Remotely operated vehicle systems, ground and air, have great potential for supporting law enforcement operations. These
systems, with their onboard sensors, can assist in collecting evidence, performing long term surveillance or in assessing
hazardous situations prior to committing personnel. Remote ground vehicles are presently used by many police departments
for ordnance clearing missions. Unmanned ground vehicles (UGVs) typically offer long endurance, and a intuitive to operate
but can be severely limited in where they can go by terrain and obstacles. Unmanned air vehicles (UAVs) have
three-dimensional mobility but have landing and takeoff restrictions, mission time limitations, and typically are demanding to
operate. A new capability has been demonstrated for the U.S. military that shows great promise for aiding police agencies. This
concept uses a shrouded rotor, vertical take-off and landing (VTOL), unmanned air vheicle to provide mobility to sensors nd
other payloads. This system can either perform surveillance from the air or travel to a remote location and land to position
onboard sensors to perform long term surveillance from the ground. This mobility platform concept can also be used to
position packages (e.g. communications repeaters) or deliver and deploy non-lethal agents. This paper presents the concept
of a small UAV, VTOL sensor mobility system for support of law enforcement operations. It tehn discusses operational
feasibility and briefly reviews demonstrations of surveillance and sensor placement operations in mility urban terrain scenarios
performed by the Space and Naval Warfare (SPAWAR) systems Center San Diego (SSC/SD) and Sikorsky Aircraft with their
full size Cypher UAV. We then discuss the practicality of reducing the size of this capability to a system small enough to be
transported in standard police vehicles and which can easily be operated by law enforcement personnel.
