Through high-performance imaging systems, space instruments allow the acquisition of new information about the observed environment and improve scientific studies. However, traditional cameras by which space instruments are typically equipped, show a limited field of view, requiring the presence of actuators coupled with moving elements to acquire the entire scenario. Indeed, moving elements increase the risk of failure, especially in the space environment, which is characterized by very harsh conditions, and where any maintenance is critical or impossible. Hyper-hemispheric panoramic cameras provide a compact solution to this issue because, thanks to their large field of view, they can acquire the surrounding scenario with a single image acquisition. Within the framework of this research, the validation of the thermo-mechanical design of the catadiopter, one of the main optics of the Hyper Hemispheric camera, was performed in the expected working temperature range from - 120 °C to 100 °C. Some mockups representative of the connection area between the mechanics and the optics were manufactured and tested with thermal cycling to assess the baseline holding strategy, which requires gluing of materials with different Coefficients of Thermal Expansion. The activity allowed the validation of the selected composite adapters (Torlon 7130) to be used as intermediate material between the optics and the holder.","PeriodicalId":153093,"journal":{"name":"2023 IEEE 10th International Workshop on Metrology for AeroSpace (MetroAeroSpace)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116128360","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The interest in testing innovative system for the early detection of biomarkers in body fluids is growing both for the industry of personalized medicine on earth both for the employment as device of self-therapy for astronauts during space exploration. In fact, astronauts involved in low earth orbit missions (international space station- commercial stations), moon exploration and, in future, Mars missions could find great advantages in the use of point of care testing devices, noninvasive and easy to use. In this work we discuss about innovative technologies for the fabrication of thin-film and microstructures, such as micro-needles, that could be used for sampling the biomarker of interest from the interstitial body fluid. The technology proposed allows a closed loop process for the fabrication and characterization in real time of the structures of interest. We describe the functionalization of the microstructures for the biomedical diagnosis and their possible functionalization in terms of drug-delivery systems. The results proposed could be used to study the effects of space on the aging process (metabolic alterations, proinflammatory state), to test alternative solutions in controlling stress state and more in general to go into details of the effect of spaceflights on protein expression.","PeriodicalId":153093,"journal":{"name":"2023 IEEE 10th International Workshop on Metrology for AeroSpace (MetroAeroSpace)","volume":"19 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125914610","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To do so, the development of very-high throughput communication systems, particularly by adopting higher signal bandwidth and wider carrier frequencies, has been essential. As a consequence, in the satellite communication scenario, the impact of linear distortions on the link budget has become relevant and therefore needs to be quantified. This paper describes a method based on the employment of a linear adaptive equalization system, which is capable to estimate the nature of the communication link, and to measure the extent of channel linear distortions. At first, an introduction to the main characteristics of modern satellite channels is given, focusing on the disturbing sources that occur during the data transmission. Then, the equalizer is described, specifically, providing an overview of the adaptability feature, which allows monitoring and measuring the extent of linear impairments. Finally, results concerning the estimation capability of the equalizer are reported.","PeriodicalId":153093,"journal":{"name":"2023 IEEE 10th International Workshop on Metrology for AeroSpace (MetroAeroSpace)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125650056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Drones for delivering goods become today an important part of modern logistics in full expansion: they allow to optimize time to delivery, decongest urban environment and reduce CO2 emissions. This class of Unmanned Aerial Vehicles (UAV) will fly in a dedicated airspace, indicated as Very Low Level (<500 feet). However, considering typical dimensions of logistic drones, compared with civil aircraft or helicopters, it is unrealistic to continuously track or control them by using radar or satellite technologies. For this reason, only operations in Visual Line of Sight (VLOS) are allowed today and one of the most important aspects related to safety of flight is undoubtedly the availability of on-board Detect and Avoid (DAA) systems: they will constitute one of the main enablers for fully automated Beyond Visual Line of Sight (B-VLOS) missions and will also enable, in the future, people transportation by drones. This paper focuses on the characterization of Texas Instruments IWR1642 Radar-On-Chip, widely used in automotive sector, to evaluate its application in an obstacles detection system for UAM operations, which will be developed in the framework of a PhD activities.","PeriodicalId":153093,"journal":{"name":"2023 IEEE 10th International Workshop on Metrology for AeroSpace (MetroAeroSpace)","volume":"278 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124468322","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Advance in material development has resulted in a wide range of new kind of materials as carbon composite and carbon fiber reinforced. The need, already consolidated, to investigate its properties (mechanical, electrical, thermal, etc.) arises and characterize the possible innovations by industrial sector such as aeronautics and aerospace, through the use of analysis techniques non-destructive (NDT). Common NDT techniques can be classified into seven major categories: visual (visual inspection), penetrating radiation (X-ray, and neutron imaging), magnetic-electrical (magnetic particle), mechanical vibration (ultrasonic, acoustic emission, and tapping), chemical/electrochemical (chemical spot testing), thermal (infrared thermography) and other optical methods (interferometry, holography, and shearography). More traditional non-destructive techniques (NDT) are not always effective as expected, and there is therefore a long-term need to use innovative NDT methods capable of provide reliable and quantitative information regarding damage status and integrity of materials. In the present work we focus on the development of specific tools of NDT for assuring the quality related to the fabrication of industrial components. The potential tool that will be take into consideration for inspection and detection of defects will mainly based on the following two main methods: ‐full-field optical techniques (such as profilometry, interferometry, sherography and thermography); ‐Laser ultrasound testing (LUT); The integrated and combinated use of different NDT (thermography, shearography and ultrasound) was necessary for a complete characterization of some types of composite materials.","PeriodicalId":153093,"journal":{"name":"2023 IEEE 10th International Workshop on Metrology for AeroSpace (MetroAeroSpace)","volume":"128 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127352797","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their physical characteristics, including low weight, electrical passivity, immunity to electromagnetic disturbances, and high sensitivity, make them highly suitable for aerospace applications. A flying test bench was recently developed at the Politecnico di Torino to evaluate the performance of optical sensors applied to an aircraft model. To allows their fruition in near real-time, it was necessary to develop a pipeline of software capable of transmitting, saving, and displaying them on the ground. To carry out in-depth tests on their reliability it is necessary to carry out more tests with different sensors and configurations. However, doing flight tests for the sole purpose of testing the data acquisition system is too expensive and impractical. Therefore, it was developed an emulator software that can generate data like that obtained from the real system, saving time and resources. Thanks to it, it is now possible to exploit the complete test bench on the aircraft for the final verification campaign only. The results are therefore very positive and demonstrate the potential of the emulator also for the most recent applications.","PeriodicalId":153093,"journal":{"name":"2023 IEEE 10th International Workshop on Metrology for AeroSpace (MetroAeroSpace)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126822952","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The availability of GNSS signals is essential for most commercial UAVs, but unfortunately, these signals can be lost in certain environments or intentionally denied in military operations. Therefore, visual-based landing systems can provide an alternative solution to enable a low-cost system for precisely landing UAVs in GNSS-denied environments. This paper overviews recent research on visual-based landing systems for multirotor UAVs in a highly unfamiliar environment. The paper presents a comprehensive review of various vision-based techniques, such as optical flow, stereo vision, monocular visual odometry, and deep learning-based methods, which have been proposed for the accurate landing of UAVs in GNSS-denied environments. This paper proposes a multi-camera landing aid system based on ArUco markers. Proposed system allows for a precision landing of the UAV with a pre-programmed approach trajectory. The paper also highlights the challenges and limitations of this topic and provides potential directions for future research.
