A new base stations placement approach for enhanced vehicle position estimation in parking lot

On Optimal Placement of Short Range Base Stations for Indoor Position Estimation

“…There are no approaches, to the best of our knowledge, that jointly consider positioning accuracy and coverage using short range BSs. Our preliminary results are available in [24] [25].…”

Base-Station Random Placement Effect on the Accuracy of Ultrawideband Body-Centric Localization Applications

“…The localization accuracy depends on various factors such as range estimation error, frequency/bandwidth used, type of environment (indoor/outdoor; highly cluttered/uncluttered), base station (BS) configuration, and the performance of the communication system. The geometric configuration of BSs used to localize the target node plays an important role in the accuracy of the localization system especially when a minimum number of BSs is used [10], [11]. Generally, four BSs are used in cuboid-shape configuration to obtain high-accuracy position estimation [7], [10]- [12].…”

On the relation between GDOP and the volume described by the user-to-satellite unit vectors for GNSS positioning

“…Although in the past receivers were typically limited to the processing of 8-12 satellites (Kaplan and Hegarty 2006), nowadays even low-cost navigation software receivers can simultaneously process signals coming from several dozens of satellites. However, there are applications in which power consumption is critical, e.g., sensor network applications, and power consumption increases with the processing of more satellites (Jwo and Lai 2007;Bais and Morgan 2012;Kiwan et al 2012). GPS and GLONASS each already provide between 8 and 12 satellites in view.…”
