Global positioning system (GPS) has undergone intensive development, starting as an
advanced specialized tool to a general-purpose gadget used in our daily lives. GPS exists in …

This paper presents a new decision-making solution based multi-measurement design
parameter for GPS baseband receiver tracking channel selection in static and dynamic real …

It has been proven that precise point positioning (PPP) is a well-established technique to
obtain high-precision positioning in the order between centimeters and millimeters. In this …

This research shows how the performance of the Precise Point Positioning (PPP) changes
with the development of GPS, GLONASS and Galileo systems. Calculations was performed …

In this paper, by using GNSS technologies, some features of the distribution and some
morphometric parameters of dams and ponds created by the Eurasian beaver (Castor fiber …

A positional accuracy obtained by the Precise Point Positioning and static relative methods
was compared and analyzed. Test data was collected using low-cost GNSS receivers of …

In some complex environments, nonline-of-sight (or multipath) usually introduces an
additional path delay to the pseudorange, which is known to be one of the most dominant …

The Global Positioning System (GPS) passed a long way of development, starting from an
advanced specialized tool, to a general purpose gadget used every day in our life. There are …

We present a method for PPP adjustment based on Recursive Least Square Estimation
(RLSE). This method estimates the stochastic model of GPS, GLONASS, Galileo and BeiDou …

The use of Low Earth Orbit (LEO) mega-constellations for Positioning, Navigation, and
Timing (PNT) services has attracted a great deal of interest, as they could complement the …
