Lockheed Martin Advanced Technology Laboratories (ATL), in conjunction with Lockheed Martin Maritime Systems and Sensors and Lockheed Martin Aeronautics Advanced Development Programs, performed a set of experiments in cooperation with the U.S. Navy involving collaborative, unmanned surface, and air vehicle mission execution. Our multi-domain, collaborative research focused on increasing unmanne...

Since 1980 the Council for Scientific and Industrial Research (CSIR) has been involved in the design and manufacture of eleven aircraft, manned and unmanned. Recently the focus has been on light unmanned research platforms to assist a number of tertiary academic institutes with research into UAS related technologies. While there is a relatively strong focus on the control and navigation aspects...

Expeditionary Warfare in the Littorals Expeditionary marine warfare involves fighting away from an established land base. It requires larger naval vessels to navigate the littorals and launch and support a landing force. In many ways, it is the maritime equivalent of urban combat, requiring operations in a noisy, cluttered environment filled with a mixture of commercial, recreational, and comba...

William Shakespeare is believed to be a significant author in the anonymous play,The Reign of King Edward III,published in 1596. However, recently, Thomas Kyd, has been suggested as the primary author. Using a neurolinguistics approach to authorship identification we use a four-feature technique, RPAS, to convert the 19 scenes in Edward III into a multi-dimensional vector. Three complementary a...

In this paper the problem of image stabilization is defined as follows: a camera mounted on a moving vehicle collects a sequence of images. The vehicle is trying to move along a smooth trajectory. In fact, however, the motion of the vehicle varies from the desired smooth motion; for a ground vehicle, this would primarily be due to roughness of the terrain. The goal of image stabilization is to ...

Aerial and ground vehicles working in corporation are crucial assets for several real world applications, ranging from search and rescue to logistics. In this paper, we consider a cooperative landing task problem, where an unmanned aerial vehicle (UAV) must land on an unmanned ground vehicle (UGV) while such ground vehicle is moving in the environment to execute its own mission. To solve this c...

The paper presents work on testing of inflatable wings for unmanned aerial vehicles (UAVs). Inflatable wing history and recent research is discussed. Design and construction of inflatable wings is then covered, along with ground and flight testing. Discussions include predictions and correlations of the forces required to warp (twist) the wings to a particular shape and the aerodynamic forces g...
