ASView Control Station Analysis

ASView Control Station Analysis
      Autonomous unmanned system design must withstand the loss of communication with the sea or ground control station since the vehicle follows a pre-programmed mission. However, equally important is the fact the Control Station (CS) should in real-time identify where the vehicle is located, its speed, its environments and the execution of the mission payload. The operator must also, be able to take over the command and the control of the vehicle or to override the mission if required. The autonomous surface vehicle the ASVGlobal manufactures encompasses the above characteristics, and the company has designed a control system that provides control mode that includes remote mode, automatic and autonomous mode to ensure the operation navigation safety.
       ASV Unmanned Marine Systems, an industry leader in research and development of Autonomous Surface Vehicle (ASV) manufactures ASView control system as shown in Figure 1 that comprises:
·       One or more CS including an ASView-Bridge user interface and an ASView-Helm remote control.
·       An ASView-Base radio enclosure
·       An ASView-Core vehicle system
·       An ASView vessel system (ASVGlobal, n.d.)

ASView is a proprietary control system for Autonomous Surface Vehicle (ASV) manufactured by
ASV Global that has mastered research in collision avoidance and safe and reliable operations over-the-horizon (ASV Global, n.d.).

ASView data depiction and presentation strategies
The operator commands, controls and communicates with the vehicle through ASView-Bridge
User Interface that is a multimodal technique providing feedback functionality, electronic nautical
charts, mission planning tools, live display of sensors data, video and radar from the vehicle as
shown in Figure 2 (ASVGlobal, n.d).

The graphic user interface can be cumbersome because it integrates all the control modes functionality that the operator cognitive workload can be very high. Every time a system becomes automatic and autonomous, the physical workload varies inversely proportional to the cognitive workload that an ergonomics standpoint, designers should consider reducing the cognitive workload by making the interface more user-friendly. ASView-Bridge desktop interface can display on the same screen as any control mode selected by the operator. The disadvantage is the operator may experience a reduced-situation awareness.
Recommendations
Because the ASV-Vessel navigates in a very complex environment, the author suggests the implementation of an artificial situation awareness functionality that demonstrates a
proactive and a predictive role. This concept necessitates the intensive application of artificial intelligence. According to McAree et al., (2017):

It has been shown how the prediction calculations can be applied to decision making tasks faced by both autonomous cars and UAS. Future work includes the application of this artificial situation awareness system within a decision-making system, both in simulation and real-world vehicles.

Unmanned Aircraft System Detect and Avoid ADS-B Technology

Unmanned Aircraft System Detect and Avoid ADS-B Technology As the number of UAV operations is expected to increase from 33,000 in 2016 to 542,000 in 2020 (FAA,2016), the FAA works toward the integration of UAS in NAS becomes imperative at a time where the agency is still finalizing the implementation of the Next Generation transportation system in the NAS. The integration of the UAS in the controlled and uncontrolled airspace is something that must happen as the engendered benefits of the different applications of UAS in dull, dirty, and dangerous environment outweigh that of the missions employing manned aircraft in the same environment. UAS routine access in the NAS must ensure safety and security come first that technologies, standards, regulations, and procedures must guarantee a “zero tolerance” operations. Among other essential technologies are the “Detect and Avoid” (DAA) mirroring the “See and Avoid” (SAA) performed by manned aircraft pilots executing the 14 CFR 91.1...

The future of Unmanned Aircraft System

Based on the article: Science, technology and the future of small autonomous drones (Floreano & Wood,2015) The more the aircraft is miniaturized, the more complex and challenging become its design and its manufacturing to ensure the propulsion and aerodynamic performance. Floreano and Wood recognize challenges, such as "the reduced power density of electromagnetic motors, decreased transmission efficiency owing to the increased dominance of friction from gears and bearings, and greater viscous losses because of reduced Reynolds numbers "  that must be considered at system design level for fixed-wing, rotorcraft or hybrid unmanned aircraft vehicle. The rotorcraft loses the propulsion performance the smaller the vehicle get; however, the UAV becomes more maneuverable because of a lower Reynolds number while a smaller fixed-wing aircraft will experience a low lift-to-drag ration, say Foreano and Wood (2015). The manufacturer must also anticipate the challenges relate to the...
