Evaluation of GPS Standard Point Positioning with Various Ionospheric Error Mitigation Techniques

Journal of Applied Geodesy, 2016
AbstractThe present paper investigates accuracy of single and dual-frequency Global Positioning System (GPS) standard point positioning solutions employing different ionosphere error mitigation techniques. The total electron content (TEC) in the ionosphere is the prominent delay error source in GPS positioning, and its elimination is essential for ...

Invariant standard positions of ordered sets of points

1995
The determination of invariant characteristics is an important problem in pattern recognition. Many invariants are known, which have been obtained either by normalization [Ar90, As94, Si94, Ro94, Vo95] or by other methods [Mu92, Re93, Fl93, We93]. This paper uses the method of normalization to derive invariants for ordered sets of points.

Efficiency of a cubic NaI(Tl) detector with rectangular cavity using standard radioactive point sources placed at non-axial position

Applied Radiation and Isotopes, 2020
Low cost scintillation detectors as compared with HPGe detectors are considered to be one of most important radiation detection tools. Therefore, these detectors can be manufactured in different shapes and work at room temperature without any cooling systems, which added an extra advantage to it.

72‐2: Standardizing Fundamental Criteria for Near Eye Display Optical Measurements: Determining Eye Point Position

SID Symposium Digest of Technical Papers, 2018
The fundamental criteria for measuring the near‐eye display eye‐point is evaluated in terms of its impact on the device performance. Several eye‐point determination techniques are used to illustrate how the various derived eye‐point locations affect primary display characteristics such as angular alignment, field of view, and center resolution.

A graduated optimization framework for robust GNSS standard single point positioning in complex environments

Measurement Science and Technology
Abstract Achieving high-precision positioning in complex environments remains a significant challenge for Global Navigation Satellite Systems (GNSSs). In such scenarios, obstacles including high-rise buildings, overpasses, mountains, and vegetation induce signal reflection and diffraction and can severely obstruct
