Characteristics of Angular Precision and Dilution of Precision for Optical Wireless Positioning [PDF]
Journal of Lightwave Technology, 2015 The challenges of optical wireless positioning are addressed in this work, by a thorough investigation of angle of arrival (AOA) positioning characteristics. The overall positioning precision for AOA positioning is studied in terms of two contributing factors—being angular precision and geometric dilution of precision (DOP).

Analysis of a HAPS-Aided GNSS in Urban Areas Using a RAIM Algorithm
IEEE Open Journal of the Communications Society, 2023 The global averaged civilian positioning accuracy is still at meter level for all existing Global Navigation Satellite Systems (GNSSs), and the performance is even worse in urban areas. At lower altitudes than satellites, high altitude platform stations (
