    For Unmanned Aerial Vehicles (UAVs) to operate in civil airspace alongside manned aviation, they must prove that they can operate to an Equivalent Level of Safety (ELOS) to that of manned aviation. Commercial use of UAVs is currently limited by their inability to detect, sense and avoid airborne hazards. This paper discusses the meaning of ELOS, and the system requirements that it creates. It also discusses Thales UK Ltd (Aerospace division) progress on Sense & Avoid (S&A) system and subsystem design to meet these requirements as part of the Autonomous Systems Technology Related Airborne Evaluation & Assessment (ASTRAEA) commercial UAV programme.

  • Cooperative control strategies for swarm of unmanned aerial vehicles under motion uncertainty

    This paper is motivated by the need to tackle uncertainty of motion of multiple co-operating autonomous vehicles which are endowed with autonomous decision-making capabilities. We argue that analysis and design of the controllers is attractive with the Kripke approach, i.e. the use of Kripke models with temporal logic statements and their automatic verification on the model. Not only is it rigorous, but it is also practical for tackling the central issue: guaranteed performance of the co-operating vehicles under sensor and communication constraints in unstructured environments. Unlike other approaches, the Kripke modelling framework is very general, so it can handle many kinds of uncertainty and dynamics in a unified way. View full abstract»

  • ASTRAEA T7 — An architectural outline for system health management on civil UAVs

    The ASTRAEA programme has as its aim the opening of unsegregated airspace to UAV traffic, allowing UAVs to routinely perform tasks currently undertaken by manned vehicles. Within this programme the aim of the Prognostics and Health Management project (T7) is to provide technology and systems so that a UAV can monitor its own state, perform real-time prognoses of its immediate and future capabilities, make decisions on how best to assist the optimal mission performance and adapt its behaviour accordingly. This technology area is seen as critical to the safe operation of a UAV in the un-segregated airspace. This paper details the relationship of the T7 project within the ASTRAEA programme and describes an architectural outline within which to develop, investigate and demonstrate civil UAV systems health management.

  • New approaches for autonomous logistics aircraft and ground systems

    Publication Year: 2007 , Page(s): 1 - 7
    Save to Project icon | Click to expandQuick Abstract | PDF file iconPDF (1473 KB)  

    This paper covers development work on a novel uninhabited autonomous cargo aircraft and ground system. We present a system that combines autonomy in the aircraft with autonomy in the ground system to create a flexible combined cargo and payload capability. The system includes several novel elements including self-balancing cargo attachment, reduced ground processing time leading to more time in the air, reduced structural requirement for cargo modules and modular design for different flight profiles, including medium and high altitude reconnaissance payloads, and low altitude cargo. Including missions from space launch to aerial mapping through to humanitarian aid. View full abstract»

    This paper reports on a SEAS DTC funded research project that aims to demonstrate the potential capability to predict the soaring possibilities within the local atmosphere in order to improve the range and endurance of autonomous airborne vehicles. A multi-agent architecture is described along with techniques for determining when and where to seek lift. Some results from initial flight trials using a surrogate manned sailplane are reported.

  • Semi-autonomous control of offshore cranes

    Offshore lifting operations are often carried out in harsh and inhospitable environments. The prevailing sea conditions cause motions of the vessel which in turn induce motions of the suspended load. The crane operator is required to try and reduce these load oscillations through manual manipulations of the slewing and luffing actions of the boom. While the operator is occupied in reducing load oscillations the overall lifting operation is not proceeding. Even the most skilled operators may not achieve enough reduction in load motions to proceed with a lift. A control scheme is proposed in which the load position in space is controlled by a combination of feed-forward and frequency domain feedback control. The feedback controller is designed to deal with disturbances and remove any residual motions from the feed-forward controller. Superposition of the control signals produces the total control action.

    This paper describes the use of a generalised knowledge database structure and protocol for the dissemination of information used in distributed applications in multi-agent systems. The protocol exploits the broadcast nature of wireless communication and is designed for distributed applications which follow symmetric models of interaction. View full abstract»
