Some remarks on geometric dilution of precision (GDOP) at user level in multi-GNSS positioning
Advances in Space Research, 2018Abstract The geometric dilution of precision (GDOP) is an important index with positioning, navigation and timing (PNT) applications. In multi-GNSS positioning, the system time offsets between different systems can be determined at user level, namely, calculated by the receiver at the cost of at least one additional satellite from each additional ...

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 ...

New Characteristics of Geometric Dilution of Precision (GDOP) for Multi-GNSS Constellations
Journal of Navigation, 2014For multi-Global Navigation Satellite System (GNSS) constellations, the Geometric Dilution of Precision (GDOP) is an important parameter utilised for the selection of satellites. This paper has derived new formulae to describe the change of GDOP. The result shows that, for GNSS single point positioning solutions, if one more satellite belonging to the ...
