Improving DGPS Accuracy using Neural Network Modeling
Back-Propagation (BP), Extended Kalman Filter (EKF) and Particle Swarm Optimization (PSO) are three of the most widely used algorithms for training feed forward Neural Networks (NNs). This paper presents an accurate DGPS land vehicle navigation system using multi-layered NNs based on the BP, EKF and PSO learning algorithms. The network setup is developed based on mathematical models to avoid ex...
متن کاملEstimating wheel slip for a forest machine using RTK-DGPS
Wheel slip may increase the risk for wheel rutting and tear up ground vegetation and superficial roots and thereby decreasing the bearing capacity of the ground, but also reducing the growth of nearby standing forest trees. With increased slip, more energy is consumed for making wheel ruts in the ground, with increased fuel consumption as a result. This paper proposes a novel method for measuri...
متن کاملAutomatic Speaker Localization and Tracking: Using a Fusion of the Filtered Correlation with the Energy Differential
This paper presents a system of speaker localization for a purpose of speaker tracking by camera. The authors use the information given by the two microphones, placed in opposition, to determine the position of the active speaker in trying to supervise the audio-visual recording. To achieve the speaker localization task, the authors have proposed and employed two methods, which are called respe...
متن کاملروش تعیین موقعیت DGPS
کاربرد لحظه ای تصحیحات فاصله در روش تعیین موقعیت نسبی DGPS، باعث افزایش دقت و اعتبار این روش شده است. در شرایطی که خطاهای بزرگی همچون تأخیرات اتمسفریک و نوسانات غیرعادی رفتار ساعت های ماهواره ها و اطلاعات مداری می توانند بر تعیین موقعیت نسبی و متحرک سیستم GPS تأثیرگذار باشند و کاربرد روش آنی و لحظهای تصحیحات در روش تعیین موقعیت نسبی DGPS برای هدف های دینامیکی برای ما دقت های تعیین موقعیت...
