This paper describes the MEDA instrument and its different subsystems, including the proposed data management architecture (hardware and software) supporting MEDA data acquisition, storage, processing and transmission. Mission planning and operations are based on Observation Tables that allow the instrument to operate completely autonomously during the mission (i.e. even when the rover computers are...
For much of the past decade NASA and other organizations have been developing the Disruption Tolerant Networking protocol suite with a primary focus on bringing internet-like functionality to space missions. Now that the core protocols are complete, engineers are beginning to incorporate DTN into mission system designs. When we look across the NASA mission needs over the next decade, there are multiple...
NASA's Unmanned Aerial System (UAS) Traffic Management (UTM) project aims at enabling near-term, safe operations of small UAS vehicles in uncontrolled airspace, i.e., Class G airspace. A far-term goal of UTM research and development is to accommodate the expected rise in small UAS traffic density throughout the National Airspace System (NAS) at low altitudes for beyond visual line-of-sight operations...
As part of The Technical Cooperation Program (TTCP), a series of trials has been held over the past three years to focus on collaboration in the unmanned maritime systems environment between the following nations: Australia (AS), Canada (CA), New Zealand (NZ), the United Kingdom (UK), and the United States (US). The trials have taken place in San Diego, CA US, Patuxent River, MA US, and Portsmouth,...
Wireless sensor networks are a cheap and versatile solution for monitoring various environments. The data gathered by these sensors is often used in research projects and science experiments. It is necessary to ensure that a certain level of security and protection is instated for the transmitted data. Current software security methods implemented on wireless sensor networks do not necessarily take...
The AUVSI Autonomous Surface vehicle event is a student-based competition where teams design, build and compete with fully autonomous surface vessel. These vehicles are required to preform many different tasks that vary from competition to competition but the ability to navigate channels marked by red and green markers and perform GPS based navigation is always a constant. Embry-Riddle Aeronautical...
Human space flight and exploration continues to be a key goal of the NASA, with an emphasis on utilizing new technologies to improve the effectiveness, efficiencies and safety associated with this endeavor, including the ground-based mission support. This search for improvement has led to cross-fertilization between the advanced software development community and the manned spaceflight operations...
Today enterprises are facing rapid and radical changes in business environments, making business agility a crucial step toward gaining competitive advantages over rivals. Service-oriented architectures (SOA) are touted as the key to business agility. However to deliver business agility with SOA effectively, business services should be designed according to SOA principles that affect business agility,...
The paper describes one of possible approaches to control of multi-variable control loop. In this case the so called main controllers, binding members and correction members are used for this one. Simulation verification of designed method of control is presented on three-variable control loop of steam turbine.
Analytical approaches based on rigorous mathematical foundation are getting more importance in service-oriented computing (SOC) research area. Defining appropriate metrics to measure service quality attributes is one of the key activities in this context which plays an important role in construction of quality service-oriented solutions. In this paper, some metrics are introduced for measuring structural...
Tele-operation of robotic platforms has long suffered from the inability of the operator to effectively perform ancillary tasks while controlling the robot. Because of the focus required to perform tele-operation, the operator is limited in their ability to use the robot to improve their situational awareness, with tele-operation often becoming a detriment to their task rather than an enhancement...
This paper presents the libdrdc data standards library containing internal nomenclature, definitions, units of measure, coordinate reference frames, and representations for use in autonomous systems research. This library is a configurable, portable C / C++ / object oriented C library developed to be independent of software middleware, system architecture, processor, or operating system. It is designed...
A set of software metrics for the evaluation of power management systems (PMSs) is presented. Such systems for managing power need to be autonomous, scalable, low in complexity, and comprised of portable algorithms in order to be well applied across the varying implementations that utilize power systems. Although similar metrics exist for software in general, their definitions do not readily lend...
