Geometric Dilution of Precision in Navigation Computation
2006 International Conference on Machine Learning and Cybernetics, 2006 In this article, QR factorization of matrix is used in geometric dilution of precision in the location of GPS. The fast algorithm about GDOP has been obtained as the result of the method. Through analyzing the correlation of PDOP (position dilution of precision), HDOP (horizon dilution of precision) and VDOP (vertical dilution of precision ...

Change of Geometric Dilution of Precision (GDOP) for integrated system
2016 IEEE Information Technology, Networking, Electronic and Automation Control Conference, 2016 With the development of the Global Navigation Satellite System (GNSS), the integrated system including two or more individual constellations will be the main navigation mode in the future. For integrated system, the Geometric Dilution of Precision (GDOP) is widely used for the selection of satellites and the evaluation of positioning accuracy.

Analytical solutions for passive source positioning and Geometric Dilution of Precision
2015 IEEE International Conference on Information and Automation, 2015This paper provides a closed form analytical solution for TDOA three dimensional (3D) acoustic source localization with four synchronized ultrasonic generators or receivers. Then a pure analytical solution for Geometric Dilution of Precision (GDOP) with four signal generators or receivers is derived instead of a least square solution. The proposed GDOP

Using Genetic Algorithms to Approximate Weighted Geometric Dilution of Precision
2016 International Symposium on Computer, Consumer and Control (IS3C), 2016 As the internet and mobile device get universal, mobile positioning in wireless communication becomes an important application. The wireless signal is influenced by many factors. Fading effect and multipath propagation increase the signal propagation time and change the angle of the received signal. All of these reduce mobile positioning accuracy.

Reducing geometric dilution of precision using ridge regression
IEEE Transactions on Aerospace and Electronic Systems, 1990 A signal processing technique is proposed for improving position-fix navigation system accuracy performance when the geometry of the navigation landmarks (e.g. sensors) are nearly collinear. In the navigation literature, the accuracy degradation associated with a nearly collinear measure geometry is termed the geometric dilution of precision (GDOP ...

Minimum of Geometric Dilution of Precision (GDOP) for five satellites with dual-GNSS constellations
Advances in Space Research, 2015Abstract The Geometric Dilution of Precision (GDOP) is a term to specify multiplicative effect of the satellite geometry on positioning and timing precision. For positioning, navigation and timing (PNT) applications with multi-GNSS constellations, the lower the GDOP values are, the more accurate the PNT solution is, and thus, the minimum value of ...
