Предложен метод построения радиокарт уровней принимаемых сигналов Wi-Fi и сигналов инерциальной навигации от встроенных датчиков микроэлектромеханических устройств, на его основе выполнена экспериментальная оценка точности позиционирования мобильного устройства внутри помещения с использованием радиокарт уровней принимаемых уровней и встроенных систем инерциальной навигации. Эксперимент проводился в развернутой сети Wi-Fi СПбГУТ и показал возможность повышения точности позиционирования на 15 % при комплексировании сигналов Wi-Fi и инерциальной навигации по сравнению с известным методом радиокарты.

Article is devoted to the proposed method for constructing radiomaps of received Wi-Fi signal levels and inertial navigation signals from the built-in sensors of microelectromechanical devices. Experimental estimation of the positioning accuracy of the mobile device indoors using radio levels of the received levels and built-in inertial navigation systems is performed. The experiment was conducted in the expanded Wi-Fi network of SPbGUT and showed the possibility of increasing the positioning accuracy by 15 % in case of combining Wi-Fi signal and inertial navigation in comparison with the known method of radiomap building.
