Three different models of terrain obstacle geometry were tested: rectangular, triangular and semi-circular, each model having the same dimensions of 300×150×50mm. Experiments were conducted using the GOM PONTOS measuring system, which made it possible to perform a dynamic analysis of the suspension system of a Cessna 152 during passing over the above variable-geometry obstacles. All experiments were conducted for three takeoff runs of 1200, 1800 and 2700 millimetres for each terrain obstacle model, respectively. The study investigated the dynamic parameters of three crucial structural elements of the aircraft's suspension system: strut, fuselage and wheel centre, for which accelerations and velocities were measured when the aircraft was passing over the obstacles. The obtained test results indicate that the velocities $v$ of characteristic measurement points related to selected structural elements of the aircraft (fuselage, wheel, strut) vary in the range of 1.1-2.56 m/s when passing through various obstacles with different approach speeds (run-up speed). The acceleration values $alpha$ change accordingly in the range 20–58 m/s2.","PeriodicalId":153093,"journal":{"name":"2023 IEEE 10th International Workshop on Metrology for AeroSpace (MetroAeroSpace)","volume":"103 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":"134522003","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 module, which is designed according to the CubeSat standard to occupy two CubeSat units, consists of a monocular camera and a wide-field-of-view laser range finder, and exploits a sensor fusion logic to provide relative position and attitude (pose) estimates. A laboratory setup is conceived and realized to characterize the pose estimation performance of the module by providing a highly accurate benchmark. Experimental tests show that the module is able to measure its relative position and attitude with respect to a target at operative distances below 2 meters with millimeter and tenths-of-degree level accuracy, respectively. Further tests on a larger-scale trajectory in an uncontrolled environment (in terms of illumination conditions and reference pose solution) demonstrate the capability to perform pose estimation up to operative distances of about 9 meters from the target, keeping reprojection errors at sub-centimeter level, and collecting reliable range finder measurements up to 30 m.","PeriodicalId":153093,"journal":{"name":"2023 IEEE 10th International Workshop on Metrology for AeroSpace (MetroAeroSpace)","volume":"26 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":"133449128","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}

With the increase of temperature, the properties of materials often change, which leads to the failure state of materials at high temperature. However, the existing material testing methods, such as hardness, are mainly based on the traditional normal temperature testing. Although high-temperature hardness testing has been developed in recent years, the common upper limit temperature of the incubator is about 1200 °C, which is far lower than the denaturation temperature of most materials. Therefore, this paper analyzes the results of the change process of the hardness value measured at high temperature with temperature, and puts forward a high-temperature hardness prediction concept based on BP neural network. Based on the measured high-temperature hardness data, it predicts the subsequent change of the hardness value with the continuous increase of temperature, and looks for the temperature point of hardness failure. Through iterative learning, the fitting degree of the calculation result of the hardness change prediction model is close to one, which can well predict the result.","PeriodicalId":153093,"journal":{"name":"2023 IEEE 10th International Workshop on Metrology for AeroSpace (MetroAeroSpace)","volume":"52 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":"129371433","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}

Low-Earth orbit (LEO) missions have investigated the quality of the GNSS observables, thus demonstrating its availability in near-Earth space. A timely case study is investigated in this work, where a CubeSat is expected to dock a LEO spacecraft while accurately tracking its baseline vector from the object. The mission scenario constitutes a unique chance for the characterization of differential GNSS measurements and the assessment of low-complexity relative GNSS algorithms oriented to collaborative navigation and Positioning, Navigation, and Timing autonomy in space. The paper analyses the simulation results for GNSS-based inter-spacecraft ranging (ISR) measurements leveraging differential, GPS, and Galileo measurements exchanged between the chaser and its mothership. Parametric results analyze the usability of ISRs in rendezvous and docking manoeuvres at LEO altitudes, by comparing their accuracy to pre-defined mission requirements. Output accuracy and precision bounds are eventually provided for the potential integration of ISR into hybrid navigation algorithms.","PeriodicalId":153093,"journal":{"name":"2023 IEEE 10th International Workshop on Metrology for AeroSpace (MetroAeroSpace)","volume":"120 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":"115086940","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}

This is fundamental to develop an analytic model for the received signal samples, which is used to synthesize the radar detector. In this respect, the aim of this paper is the design of suitable learning tools to study some important statistical properties of the sea-clutter environment perceived at the nodes of a multistatic/polarimetric radar system. The study is complemented by the use of radar returns measured with the Netted RADar (NetRAD), which collects simultaneously monostatic and bistatic measurements. Precisely, the homogeneity properties of the data in the slow-time domain are first assessed resorting to Generalized Inner Product (GIP) based statistics. Then, the possible presence of structures in the clutter covariance matrices (both inter and intra channels) is investigated through ad-hoc statistical tools. The results show that the data, regardless the polarimetric/geometric configuration, can be modeled as drawn from a stationary process within the coherence time. Moreover, for both the monostatic and the bistatic returns the structure of the covariance matrix depends upon the polarimetric/geometric configuration of the sensing system.","PeriodicalId":153093,"journal":{"name":"2023 IEEE 10th International Workshop on Metrology for AeroSpace (MetroAeroSpace)","volume":"148 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114057149","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}

In the field of satellite relative operations, CNNs are an effective method for detecting and classifying an uncooperative target spacecraft in images acquired by a chaser satellite that has to ensure the safety of the satellites when flying in close proximity. In this paper, we propose and validate through experimental tests the first part of a pipeline based on computer vision algorithms for proximity navigation between uncooperative satellites. Specifically, the computer vision algorithms employed are the state-of-the-art CNN called You Only Look Once version 7 tiny (YOLOv7-tiny), used to detect the target satellite and reduce the search field of relevant features on its surface, and the feature detector called Oriented FAST and Rotated BRIEF (ORB). The validation of the measurement system and the computer vision algorithms is carried out using a representative laboratory facility, paying particular attention to computing time and performance metrics of the image analysis algorithms devoted to object detection and feature detection.","PeriodicalId":153093,"journal":{"name":"2023 IEEE 10th International Workshop on Metrology for AeroSpace (MetroAeroSpace)","volume":"22 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":"122483986","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}
