6.4 Control Station Analysis

Control Station Analysis
            Recent advancements in unmanned surface/underwater vehicles have shown their ability to relieve man of the dull, dirty, dangerous and deep hazards associated with maritime operations.  However, as with other unmanned systems (UxS), unmanned surface vehicles (USVs) and unmanned underwater vehicles (UUVs) are unable to realize their full potential due to limitations in providing the operator with essential data and communication strategies to support situational awareness.  In an effort to mitigate loss of operator SA, it is necessary for unmanned systems to depict and present data in a form and manner capable of supporting the operator’s decision making process while at the same time not promoting situation overload or saturation.  Recent developments in control station design architecture have shown promising results in minimizing data overload while enhancing operator SA.
Limitations
Commonality among UxS control stations has restricted an operator’s ability to quickly adapt to the command and control infrastructure essential to many different operating platforms. This inability of an operator to quickly adapt to different command architectures, requires specialized training for different operating systems and is therefore not cost effective or sustainable (Raytheon, 2011).
Increased use of unmanned surface vehicles (USVs) by the Navy has identified limitations in the command and control of these systems due to the limited communication capabilities from one surface vehicle to another.  In an effort to enhance range and communication strategies the Navy relies on a communication network comprised of manned/unmanned aircraft and/or satellite communications (Gonzales & Harting, 2014).
The PGCS essentially allows one operator to efficiently control the USV beyond line of sight (BLOS) operations while also controlling an UAS via multiple displays and waypoint navigation effectively controlling the communication bridge from one control station.  One operator + One Control Station x multiple unmanned platforms = reduced costs.
Solutions
The UAV Factory© developed a portable ground control station (Figure 1) designed specifically for controlling all manner of unmanned vehicles.

The control station or PGCS is comprised of commercial-off-the-shelf (COTS) products providing a flexible yet universal solution to UxS command and control (C2) (UAV Factory, n.d.).
            Equipped with a durable Panasonic CFR-31 Toughbook and capable of configuring dual 17” touch screen displays it provides the operator with multiple displays formatted to present data determined by the operator as essential to C2 of the particular UXS platform, regardless of the operating environment.
            Using a point-and-click command architecture, the operator has the ability to navigate the unmanned platform via waypoint navigation software.  This mouse based C2 strategy allows the operator to quickly transition between different unmanned systems without extensive training or considerations regarding currency in command of a particular operating platform.
            Using a portable environmentally protected case, electronic equipment can be configured to the operators needs by use of a comprehensive set of connections which allows the user to install application specific hardware such as autopilot RF-modems, video receivers, data links, data storage and recording devices ( (UAV Factory, n.d.).
            Power considerations allow the PGCS to be used anytime anywhere, using 10-32 VDC capability or dual hot-swappable Lithium Ion battery ports capable of providing up to two hours of operation while the integrated power distribution system provides two 12 VDC, 50 W power outputs for the equipment in the electronics compartment as well as external devices that are used in conjunction with the GCS.  (UAV Factory, n.d.).
Recommendation
Use of proprietary closed platform control systems, requires higher development costs, specialized training for operators and maintenance personnel, and increased costs associated with support infrastructure.
Realization of an open control interface command structure, like that of the PGCS, can reduce unnecessary costs, encourage innovation, improve quality of operations and maximize operator qualifications (Raytheon, 2011).
This synergistic design logic will increase ground station functionality, facilitate C2 of multiple vehicles and sensors, while enhancing an operators situational awareness across all levels of unmanned systems (Raytheon, 2011).
