Despite its capability of measuring out of plane displacement gradients in the sub-micrometer range, and the possibility of successfully detecting defects (delaminations, debondings, impacts) without compromising the investigated structure (which is very important in the aerospace field), Shearography usually remains a qualitative technique. This is due to several uncertainty sources and the difficulty...
A wind tunnel test campaign has been conducted prior to the landing of the Exomars2016 EDM module on the Meridiani Planum on the 19th of October 2016. Test were perfomed in the Mars wind tunnel facility at Aahrus University (DK) under the 2015 Europlanet Call. The facility was available for a 5 days campaign where different environmental configurations were tested and both a full scale DREAMS Metmast...
In order to reduce measure standard uncertainty and achieve precise calibration of Port Quick Leak Detector in different temperatures under full range, the special calibration apparatus was designed on basis of theoretical studies. This apparatus consists of pressure standard leak system, calibration system, temperature control system, gas supply and pump system. Pressure standard leak system is made...
Over the last years, nanosatellites based on the CubeSat standard have been increasingly exploited by both academic institutions and commercial companies. The low cost and short development time of CubeSats make such miniature spacecraft interesting for a variety of applications. A particularly appealing future field of application for nanosatellites is On-Orbit Servicing of existing orbital assets...
Vacuum gauges used in deep space exploration are always calibrated in the laboratory. The temperature in the laboratory is about 23 °C± 3 °C, which is different from the environment temperature where the vacuum gauges is used. It will lead to the uncertainty of measurement results for vacuum gauge. Based on the requirement of the calibration for vacuum gauge in deep space exploration, a vacuum calibration...
The paper describes the design, development and testing of an automated, programmable pressure measurement system based on low-cost sensors. To improve the accuracy of the measure, multiple sensors with different pressure range are used. A micro-controller drives the automatic switching logic and activates the suitable sensor for the measured pressure range. A practical application is described, where...
The skyrocketing development of the civilian drones' market, which follows the military solutions, results in boosting research on UAV avionics systems. The research includes a development of classic navigation and control as well as innovative methods that require e.g. infrared and visible light cameras, laser or magnetic field sensors. In this paper, we focus on the research on UAV's navigation...
In the last few years, Unmanned Aerial Systems (UAS) have been attracting enormous research interest, being employed in military and civilian missions (e.g. search and rescue, disaster assessment, urban traffic monitoring, 3D mapping, etc.) that would be risky or impossible for a human to perform. For autonomous or aided operations (e.g. automatic or aided landing), it is crucial to have on board...
The paper introduces an on-orbit calibration method for aerospace hall current sensor based on excitation response with verification by experiments. The method is applicable for long-life on-orbit spacecraft without manual calibration periodically, and it is possible to improve measurement reliability and accuracy for the hall current sensor in a long-term work life.
Safe indoor flights of unmanned aerial vehicles (UAVs) requires an independent measurement systems, that will enable efficient navigation in the absence of GPS data. One of the many solutions currently being developed is the use of information about changes in the value of the local magnetic field. This paper presents ways of recording, visualizing and mapping local magnetic field changes that can...
The focus of the project is to create new approaches to the study of the past through the use of innovative aero-space technologies to measure, analyse and reconstruct the ancient landscape and its remaining natural and anthropic traces. The équipe, based at the University of Padua, is constituted by archaeologists, egyptologists, mechanical and software engineers, physicists and computer scientists...
