This paper presents an ultrasonic based indoor positioning (ICKON) system for indoor environments. The ICKON uses only ultrasonic signals and calculates the position of the mobile platform at centimeter-level accuracy. In this system, ultrasonic transmitters are located at known fixed positions and periodically send signals. The receiver is on the mobile unit and uses the time difference of arrival...
Nowadays, indoor and outdoor location-aware applications has been become increasingly widespread. Location information for outdoor applications is obtained from well-known systems such as GPS and GLONASS. Although there are several systems for indoor localization, there is not a consensus on them like the outdoor. In this study, several aspects of indoor localization systems such as system topologies,...
Localization plays an important role in many applications. One of the positioning systems developed for indoor environments is İÇKON that can calculate the position of an object at cm accuracy by using pure ultrasonic signals. In this study, the ICKON system is switched to wireless sensor network to reduce setup time, and a mobile application is developed to determine transmitter positions. Switching...
Localization plays an important role in many applications such as robotic, signal processing and sensor networks. In the previous study, an indoor positioning system (İ×KON) was developed. The İ×KON uses only ultrasonic signals to calculate the position of mobile unit at cm level accuracy. For this accuracy, transmitter positions must be known in advance. These directly affect the mobile unit position...
Position measurement is one of the primal problems in wide range of applications such as air/land/marine vehicles tracking, automation systems, and equipment tracking in medical sector, robotics and sensor networks. Location information in outdoor application can be easily obtained from well-known systems such as GPS and GLONASS. Since GPS signal is not available in indoor area, several positioning...
Localization is an important problem for robotics and mobile platforms. Although there is some globally accepted positioning systems (e.g., GPS, GLONASS) for outdoor environments, there is not such a system for indoor. In this study, an ultrasonic based positioning system (SESKON) is developed especially for indoor robotic applications. The SESKON uses only ultrasonic signals, so it differs from other...
