Abstract. Tracking the members of civil protection or emergency teams is still an open issue. Although outdoors tracking routinely performed using well-seasoned techniques such as GNSS, this same problem must be solved for indoors situations. There exist several approaches indoor positioning, but these are not appropriate staff in real-time: some rely on existing infrastructures; others have be...

The broadcast ionospheric model is mainly used to correct the delay error for single-frequency users. Since BeiDou global correction (BDGIM) a novel BDS-3, its performance was analyzed through single point positioning (SPP) in this study. Twenty-two stations simultaneously receiving B1C, B2a, B1I and B3I signals were selected from International GNSS Service (IGS) Monitoring Assessment System (i...

Abstract In recent years, we have witnessed a growing demand for GNSS receiver customization in terms of modification signal acquisition, tracking, and processing strategies. Such demands may be addressed by software-defined receivers (SDRs) which refers to an ensemble hardware software technologies allows re-configurable radio communication architectures. The crux the SDRs is replacement compo...

Objective: The study objectives were to identify factors affecting extension ladders' angular positioning and evaluate the effectiveness of two anthropometric positioning methods. Background: A leading cause for extension ladder fall incidents is a slide-out event, usually related to suboptimal ladder inclination. An improved ladder positioning method or procedure could reduce the risk of ladde...

Unmanned Aerial Vehicles (UAVs) have emerged as suitable platforms for transporting and positioning communications nodes on demand, including Wi-Fi Access Points cellular Base Stations. This paved the way deployment of flying networks capable temporarily providing wireless connectivity reinforcing coverage capacity existing networks. Several solutions been proposed UAVs acting Flying (FAPs). Ye...
