A blend of two or more sequences of empirical variances has frequently appeared as a sequence of empirical variances. The distributions of these sequences differ. Then there’s the issue of estimating the variance of the fundamental distribution. The Perg mixed distribution of empirical variances is discussed, which is made...

The subject of this study is a GPS measurement method that achieves maximum measurement accuracy while requiring the least amount of work, i.e. an optimal solution for the GPS measurement process is proposed. Furthermore, the formulae for estimating the measurement accuracy of anticipated GPS base vectors are provided for...

The overall measurement error is represented as a random process in time, with the error structurally split into three groups due to three different sources, according to the paper. The first group includes time variable errors caused by tropospheric-ionospheric influences, the second group includes time variable errors caused by...

The findings of a study done on five distinct types of automobiles in a specified test site are presented in this paper. The goal was to see how the effect of the test site discontinuity influences variations in comfort as a function of speed and the five distinct classes...

The oscillators are at the heart of a satellite-based navigation system, as they are required for precise timing. The goal of this study is to find out how important space-based oscillators are for improving the performance of GNSS and satellite-based augmentation systems (SBAS). The NIGCOMSAT-1R navigation payload, which employs...

When technology advances, we cannot afford to ignore any wearable device that is most suitable for pregnant women. Our proposed system is a wearable device that tracks expectant mothers’ health and transmits data to the appropriate physician, especially in rural areas. Doctors will offer higher quality medical services and...

This chapter introduces two type helix antennas. One is a broadband inverted conical circularly polarized quadrifilar helix antenna (QHA). The antenna has many good characteristics, including wide beam and broad bandwidth, which are achieved by utilizing inverted conical geometry and adjusting the dimensions of the inverted conical support. The...
