| Summary: | This paper will introduce and describe the goals, concept and overall approach of the European 7th Framework Programme's project named CLOSE-SEARCH, which stands for 'Accurate and safe EGNOS-SoL Navigation for UAV-based low-cost SAR operations'.
<br><br>
The goal of CLOSE-SEARCH is to integrate in a helicopter-type unmanned aerial vehicle, a thermal imaging sensor and a multi-sensor
navigation system (based on the use of a Barometric Altimeter (BA), a Magnetometer (MAGN), a Redundant Inertial Navigation
System (RINS) and an EGNOS-enabled GNSS receiver) with an Autonomous Integrity Monitoring (AIM) capability, to support the
search component of Search-And-Rescue operations in remote, difficult-to-access areas and/or in time critical situations. The proposed
integration will result in a hardware and software prototype that will demonstrate an end-to-end functionality, that is to fly in patterns
over a region of interest (possibly inaccessible) during day or night and also under adverse weather conditions and locate there disaster
survivors or lost people through the detection of the body heat.

This paper will identify the technical challenges of the proposed approach, from navigating with a BA/MAGN/RINS/GNSS-EGNOSbased
integrated system to the interpretation of thermal images for person identification. Moreover, the AIM approach will be described
together with the proposed integrity requirements. Finally, this paper will show some results obtained in the project during the first test
campaign performed on November 2010. On that day, a prototype was flown in three different missions to assess its high-level performance
and to observe some fundamental mission parameters as the optimal flying height and flying speed to enable body recognition.
The second test campaign is scheduled for the end of 2011. |
