Special Issue Information

Dear Colleagues,

The field of positioning systems has seen significant advances in recent years, with various representative systems such as Global Navigation Satellite System (GNSS), Inertial Measurement Unit (IMU), Radar, and Lidar being used to calculate positions. However, with the increasing demand for more accurate and reliable position information, the limitations of these existing technologies have become apparent. As a result, there is a growing need for new positioning systems that can overcome these limitations and provide more accurate and reliable location information. The Special Issue on "New Sights and Applications in Positioning Systems" aims to address this need by exploring the latest advances and innovations in the field, with a focus on new methods, technologies, and applications for positioning systems. The authors will provide valuable insights into the challenges and opportunities facing this field.

The use of ultra-wideband (UWB) signals for local positioning is very attractive for practice, because such signals have the potential to provide centimeter precision. In this paper, we consider wireless ranging (distance measurement) and positioning, using one of the kinds of UWB signals, i.e., chaotic radio pulses, which are noise-like signals with no constant shape. The distance measurement is based on an assessment in the receiver of the power of UWB chaotic radio pulses emitted by the transmitter. A new method for estimating their power and its experimental implementation is proposed and described. Experimental layouts of the transmitter and receiver and the principles of their operation are described. To determine the main features of this method under real signal propagation conditions, full-scale indoor measurements were carried out, and statistical estimates of the accuracy were made. We present the results of experimental testing of the proposed approach for positioning the emitter relative to a system of anchors in an office space 6 × 6.5 m2 in the mode of measuring object coordinates on a line and on a plane. The mean absolute error (MAE) of distance measurement (1D) was 25 cm, and the root mean squared error (RMSE) was 39 cm. When positioning on a plane (2D), the MAE of coordinate estimation was 34 cm and the RMSE was 42 cm. The proposed distance measurement method is intended for use in wireless UWB transceivers used in wireless sensor networks. Full article
