An Approach to Improving GNSS Positioning Accuracy Using Several GNSS Devices [PDF]

open access: yesRemote Sensing, 2021
Single point positioning (SPP) mode, related to pseudorange measurements, limits the level of accuracy to several meters in open sky and to several dozens of meters in urban canyons. This paper explores the effect of using a large number of SPP observations from low-cost global navigation system (GNSS) receivers, smartphones, and handheld GNSS units ...
