Under this environment, the scalar-based GPS receiver is unable to provide navigation solutions. For a vector tracking loop based GPS receiver (VTL-R), a Kalman filter is introduced to complete the signal tracking and navigation computation together. When the available satellites are less than 4, the vector tracking loop based receiver can still work. However, the accuracy of navigation solution degrades over the time. In this paper, a barometric altimeter is introduced to provide the height information for the vector tracking loop. The new measurement model of the barometric altimeter aided vector tracking loop is presented. The method is implemented and evaluated based on a software defined GPS receiver. The results demonstrate the barometric altimeter can obviously slow down the divergence of the navigation filter of the vector tracking loop based receiver when the available satellites are less than 4.","PeriodicalId":335344,"journal":{"name":"Journal of aeronautics, astronautics and aviation, Series A","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124670539","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}

Results reveal the size of wake flow is smaller and the structure is also delay to develop.

How to accomplish fast and effective coast surveillance impacts safety concerns in beach activities. This paper proposes a submerged shark detection, such as the white shark, using image identification from low altitude drones. The image identification is set on a drone to train real datasets of a 2.5 m long and 0.945 m^2 shark model. The Haar feature-based cascade classifier is used to detect regions of interest (ROI) to extract some features to classify water area with a shark. The proposed system is tested in two different uncontrolled areas in Kenting coast, Taiwan by presenting contrasted conditions. The adopt technique reaches an average of 19 frames/second based on different altitudes of drone experiments from 8 to 22 m above sea level in static and dynamic detections for 30 minutes endurance. The system achieves a true detection’s average of 99.5% by correct classification and the mean score on total false positive detection is 3.85%. The detection rate varies with the altitude and the weather conditions which is sensitive in building an altitude-based image detection system. The experiments show very effective results to detect sharks on sea coast to reach a lower false positive detection rate.","PeriodicalId":335344,"journal":{"name":"Journal of aeronautics, astronautics and aviation, Series A","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121051601","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 recognition of fatigue status of pilot status is of utmost significance. We proposed a new deep learning model via analyzing electroencephalogram signals to reduce the complexity of feature extraction and improve the accuracy of recognition of fatigue status of pilots. We firstly applied filters on decomposing electroencephalogram signals of pilots to extract the δ wave (1~3 Hz), θ wave (4~7 Hz), α wave (8~13 Hz) and β wave (14~30 Hz), and the combined representation of them were as de-nosing EEG signals. Then we used deep contractive auto-Encoding network to reduce the complexity of de-nosing EEG signals and gained learning features. Lastly, we applied Softmax classifier on learning features and the experimental results showed that the proposed deep learning model had a nice recognition, and the accuracy of recognition was up to 95.83%, which meant that the proposed method performed excellently compared with the state-of-art methods.","PeriodicalId":335344,"journal":{"name":"Journal of aeronautics, astronautics and aviation, Series A","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130648159","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 vector tracking loop employs a central Kalman filter to complete the tracking and navigation together. In this way, the channel with strong signal can aid the weak signal channel. However, the drawback is that the faulty or low-quality channel will definitely affect the performance of the vector tracking loop and integrated navigation system. To solve the problem, this paper proposed a new fault tolerant vector tracking loop (NVTL) utilizing a pre-filter structure. A fault detection function utilizing the innovation sequence is employed to adaptively tune the measurement noise parameters of the designed pre-filters. Based on a software-defined GNSS receiver, the deep integration system was developed. The test results show that the proposed faulty tolerant vector tracking loop based GNSS/SINS deeply integrated navigation system can effectively improve the robustness and position accuracy under the presence of low-quality or faulty channels.","PeriodicalId":335344,"journal":{"name":"Journal of aeronautics, astronautics and aviation, Series A","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130483376","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 paper applied an optimization mathematic planning model to formulate the optimum arrangement of arrival/departure times for international/domestic flights within one hour. This formulation is based on the taxiing speed and waiting time between runway and apron to meet airport capacity constraints. This study selects flight information, timetables, airfield layout, and airfield operations of Taipei SongShang Airport as parameters. Results show that the optimal timetable is better than the current timetable not only to maintain the minimum total taxiing time between runway and apron at 10 minutes per flight but also to show some time points to be too shortest apron operational times and to serve many flights. The outcome issues can provide the airport authorities set service standard of shift backward times of gate timetable to enhance the airfield operation efficiency and suggest the airlines how to allocate the departure flights at the same time point of the neighbor aprons to avoid physical airfield congestions.","PeriodicalId":335344,"journal":{"name":"Journal of aeronautics, astronautics and aviation, Series A","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123953138","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}
