Improving Accuracy of DGPS Correction Prediction in Position Domain using Radial Basis Function Neural Network Trained by PSO Algorithm
Differential Global Positioning System (DGPS) provides differential corrections for a GPS receiver in order to improve the navigation solution accuracy. DGPS position signals are accurate, but very slow updates. Improving DGPS corrections prediction accuracy has received considerable attention in past decades. In this research work, the Neural Network (NN) based on the Gaussian Radial Basis Fun...
متن کاملDGPS/INS data fusion for land navigation
The interest for land navigation has increased for the recent years. With the advent of the Global Position System (GPS) we have now the ability to determine the absolute position anywhere on the globe. The problem is that the GPS systems work well only in open environments with no overhead obstructions and they are subject to large unavoidable errors when the reception from some of the satelli...

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...
