Precise point positioning (PPP) is a high-precision global navigation satellite system (GNSS) positioning technology. Under PPP, the major research problems include the convergence time to obtain sufficient positioning accuracy from the start of positioning and the accuracy after convergence. However, most of these studies used archived correction data, and the manner of obtaining the correction data from satellite broadcasts in the actual environments was not discussed sufficiently because only a few low-cost GNSS receivers that can receive new signals are available. In this study, we evaluated the real-world performance of PPP in urban areas using Pocket SDR, which is a GNSS software define radio (SDR) receiver that consists of a low-cost (a few hundred dollars) RF front-end and an attached open-source GNSS-SDR receiver that supports GPS, GLONASS, Galileo, QZSS, BeiDou, NavIC, and SBAS.
