Global positioning system (GPS) has been demonstrated to be a valid and efficient system for various space applications in low Earth orbit (LEO) and medium Earth orbit (MEO), such as for location determination and time synchronization. However, in highly elliptical and high Earth orbits (HEO), the number of existing space applications is much smaller because of the very weak power of the receiv...

The performance of acoustic passive source localization based on a multiple sensor system does not only depend on the chosen estimation algorithms, but is also strongly correlated to the geometry of the sensor network and the position of the source. This thesis approaches the optimization of the estimation procedure, by utilizing an optimal microphone setup. In order to carry out this optimizat...

The Global Navigation Satellites Systems (GPS, GLONASS and the future GALILEO) has proven to be a useful tool for precision deformation monitoring applications in structural engineering. For continuous structural deformation monitoring on an epoch-by-epoch basis it is desirable for a measurement system to deliver equal precision in all position components, all the time. However, the quality of ...

مسئله پیدا کردن مکان متحرک بی سیم، مقارن است با عملیات های نظامی در طول جنگ جهانی دوم، به طوری که در آن زمان یافتن مکان سربازها در مواقع اضطراری امری حیاتی بوده است. حدود 20 سال بعد در طول نبرد ویتنام، وزارت دفاع آمریکا یک سری از ماهواره های سیستم موقعیت یاب جهانی (gps ) را برای حمایت نبردهای نظامی در مناطق جنگی، راه اندازی کرد. در سال 1990 سیگنال های ماهواره های gps در دسترس سازمان های خصوصی و...

Micro-Electro-Mechanical Sensor (MEMS) inertial navigation sensors (INS) and GPS are attractive technologies for low-cost navigation applications. In the loosely-coupled integration schemes, GPS provides the position and velocity for real-time correction of the inertial sensor errors as well as the navigation parameters of the MEMS-INS. As an efficient estimation algorithm, the Kalman filter (K...
