Stochastic models play an important role in achieving high accuracy in positioning, the ideal estimator in the least-squares (LS) can be obtained only by using the suitable stochastic model. This study investigates the role of variance component esti

To extract valid results from time series analysis of tides observations, noise reduction is vital. This study aimed to use a precise statistical model to investigate noise types. Noise component amplitude of the proposed model was studied by Least S

Exploiting the reflected signals from the surface of the Earth to provide information about the reflecting surface is the primary concept of GNSS Interferometric Reflectometry (GNSS-IR). One of the most common usages of GNSS-IR is the estimation of t

Today, satellite altimetry is capable of observing the instantaneous sea level and is regarded as a standard tool in the study of waters level variations on both regional and global scales. In this research, we have introduced a software package unde

Using a coastal Global Navigation Satellite System (GNSS) station, one can measure sea surface height (SSH) using GNSS Interferometric Reflectometry (GNSS-IR) technique as it gives vertical distance between the antenna and the reflective surface in a

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 observations by using RLS-Variance Components Estimation (RLS-VCE). The accuracy
