Review of Article: Codeword-based Data Collection Protocol for Optical Unmanned Aerial Vehicle Networks

Review of Article:  Codeword-based Data Collection Protocol for Optical Unmanned Aerial Vehicle Networks In the world of data transfer, optical data collection protocols for optical communication have a transfer rate of up to 2.5 Gbit/s.  Light of Sight (LOS) Free Space Optical (FSO) communication can support the high level of data connectivity required when multiple airborne Unmanned Aerial Vehicles (UAVs) are involved in a cooperative sensing scenario (Ramdhan, 2016).  This article proposes the protocol where collected data is ferried to a location where it can be analyzed, processed, stored, or forwarded to remote locations with cloud capabilities and viewing the collected data. This dissemination of data through FSO has unique features for large bandwidth, high data rate, license free requirement, low power and low mass requirement (Ramdhan, 2016).  This surpasses the traditional RF method of data transfer in speed, security, and freedom to use without fr...

Mining Exploration Unmanned Aerial Vehicle Data Protocol

Mining Exploration Unmanned Aerial Vehicle Data Protocol In the vast Yukon area, a mineral exploration team uses a UAV such as the eBee by Sensefly to create elevation model orthomosiac high resolution imaging.   This geospatial high definition 3D imagery is shown to clients exploring areas of particular interest such as ridge tops or areas that may be untouched and contain precious metals (Sensefly, 2015).   They can reach these regions by helicopter, set up a mobile control station, and use a hand auger to take soil samples.   Soil samples offer miners a broad idea of the mineral content.   The UAV 3D mapping allows the client to explore particular areas with quickness and leave a minimal environmental footprint. The eBee is a small ultra- light EPP foam and carbon construction weighing 1.5 pounds with a rear facing propeller that is hand launched and navigated through predetermined waypoints.   It is designed to be user friendly and require no UAV...

UAS Sensor Selection and Placement

UAS Sensor Selection and Placement             The Parrot Disco provides exceptional quality video and photography for its price.   This fixed-wing Unmanned Aerial Vehicle (UAV) weighs 1.6 pounds and is constructed from lightweight flexible plastic foam.   Its single rear propeller is positioned in the rear and its propulsion system is strong enough to propel the UAV up to 50 miles per hour for up to 45 minutes (Goldman, 2016).   Exteroceptive and proprioceptive sensory equipment includes an air data pitot static system for airspeed, an accelerometer, gyroscope, magnetometer, and GPS for navigation.   The Control Hub and Universal Computer Kit or CHUCK allows the Parrot Disco to be hand-launched while it autonomously ascends to 50 feet and circles until it receives commands.             Command and control of the Parrot Disco is semi-autonomous...

Unmanned Systems Assets for Search and Rescue

Unmanned Systems Assets for Search and Rescue Raymond J. DeMarco III Embry Riddle Aeronautical University Worldwide Unmanned Systems Assets for Search and Rescue             Unmanned maritime assets are important in Search and Rescue (SAR) operations associated with sport and social water activities.   SAR teams can augment their search ability and ultimately reduce crucial rescue response time.   NATO’s Center for Maritime Research and Experimentation’s (CMRE) project to aid in rescue missions is known as the Integrated Components for Assisted Rescue and Unmanned Search (ICARUS) operations.   This project’s efforts focus on developing unmanned maritime platforms to aid SAR and disaster relief.   Unmanned SAR efforts compliment SAR teams in dangerous scenarios and adverse environmental conditions while minimizing danger risk to rescuers (Matos, 2013).   ...
