In this paper, coverage and performance assessment for sub-urban, urban and coastal areas in Singapore for up to 400 feet (121.92 metre) altitude is first performed. Utilizing the collected measurements with Atoll radio planning tool, a calibrated Standard Propagation Model (SPM) is proposed to simulate 4.5G coverage availability for entire Singapore airspace up to 400 feet altitude. This calibrated SPM considers pathloss correction due to angular-depression between UAS’ altitude and cell tower height to improve coverage prediction accuracy. The accuracy of less than 8dB error in variance between simulation and experimental results have been achieved. The calibrated model will be used to support the uTM-UAS to indicate suitable airspace in terms of communication coverage and performance to ensure safe UAS operations.","PeriodicalId":246293,"journal":{"name":"2018 International Conference on Unmanned Aircraft Systems (ICUAS)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115782862","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 study offers a new approach for improving the FWA autonomy by enabling real-time sensor data fusion, targeting and re-targeting capabilities, new analytical/ numerical trajectory and attitude control solutions, and target-relative guidance. Existing FWA dynamical models are based on the traditional decoupling of their motion. This paper extends the utility of the concept of an instantaneous screw axis in guidance and control thereby promoting a new vision to general 6-degrees-of-freedom rigid body motion control. The existing flight vehicle guidance and control functions are mainly iterative and implicit, platform-specific, utilize pre-determined target states or way points, and executed typically utilizing the decoupled motion dynamical models. The research presented in this paper produces the GNC framework with the real-time target-relative guidance system, which is explicit and free of iterations, provide an onboard computation of the target states, executable for an uncoupled motion, and adjustable to various FWA and other unmanned aerial system platforms. An illustrative example is considered for a FWA maneuver in a vertical plane.","PeriodicalId":246293,"journal":{"name":"2018 International Conference on Unmanned Aircraft Systems (ICUAS)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124896614","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 proposed approach consists of two phases: first, an off-line path planning computes the optimal global path in a static environment considering the risk; then, taking into account a dynamic risk-map, an on-line path planning adjusts and adapts the off-line path. The risk-map is a location-based map, in which each cell represents a specific location with an associated risk-cost.The off-line path planning is performed by the riskA* algorithm. It is based on the well-known A* algorithm, enhanced considering the minimization of the risk-cost. The off-line path planning is executed in a static environment and it has no time constraints. On the contrary, the on-line path planning needs to adapt the path in a short time, thus a fast response constitutes a critical design parameter. The on-line path planning is performed by a novel algorithm, called Borderland. Borderland uses a check and repair routine, then it identifies and adjusts only the portions of path involved by changes in the dynamic risk-map. Simulation results corroborate the validity of our approach.","PeriodicalId":246293,"journal":{"name":"2018 International Conference on Unmanned Aircraft Systems (ICUAS)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121803828","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}
