High-precision Autonomous Flight in Constrained Shipboard Environments
This paper addresses the problem of autonomous navigation of a micro aerial vehicle (MAV) inside of a constrained shipboard environment to aid in fire control, which might be perilous or inaccessible for humans. The environment is GPS-denied and visually degraded, containing narrow passageways, doorways and small objects protruding from the wall, which makes existing 2D LIDAR, vision or mechani...
متن کاملShipboard Automatic Watchstander
Crew sizes in the Navy and Coast Guard continue to decrease. Optimally or minimally manned crews complete ever more complex and varied mission sets. Accordingly, crews rely on sensors and automatic operation to perform a host of duties formerly completed manually. The Non-Intrusive Load Monitor (NILM) provides a low cost, low-maintenance, rugged, easily installed tool for machinery monitoring f...
متن کاملControl of Shipboard Cranes
We propose a new shipboard crane configuration for offloading cargo in open seas. We show that the “Maryland Rigging” crane of ship’s configuration, used in association with a friction control mechanism, provides a very effective method for reducing load pendulation caused by the motion of the crane in the roll direction. The effectiveness of the control technique is obtained by comparing the p...
متن کاملVisualization for Shipboard Power Systems
Shipboard Power Systems (SPS) are geographically spread all along the ship. It consists of various components such as generators, cables, switchboards, circuit-breakers, bus transfer switches and loads, all interconnected with each other and located at various places (decks) on the ship. Geographical information on these components is required to assess the impact of faults caused due to battle...
متن کاملShipboard Wireless Site Selection Techniques
WLAN technologies appear tailor-made for shipboard applications. Wireless technology holds the promise of freeing up manpower, reducing crew size while dramatically improving the way hull, mechanical and electrical systems and subsystems are designed, installed and maintained. This paper presents a process template to assist the information and process control technologist in successfully deplo...
