TL;DR: For IRNSS this article presents for the first time DISBs with respect to the L5/E5a signals of GPS, Galileo and QZSS for a mixed-receiver baseline, and demonstrated that single-frequency ambiguity resolution is tremendously improved when the multi-GNSS observations are all differenced withrespect to a common pivot satellite, compared to classical differencing for which a pivot satellite is selected for each constellation.

TL;DR: Numerical insights are provided into the role taken by the multi-GNSS integration in delivering fast and high-precision positioning solutions (sub-decimeter and centimeter levels) using PPP-RTK.

TL;DR: The results show that the IRNSS L5-signal has comparable noise characteristics as that of the other L5/E5a-signals, and for single-frequency carrier phase-based positioning and navigation, the results show better ambiguity resolution performance of L4/E4a-only processing than that of L1/E1- only processing.

TL;DR: Results demonstrate that these biases could seriously affect the integer ambiguity resolution for attitude determination using mixed receiver types and that a priori correction of these biases will dramatically improve the success rate.

TL;DR: Analyses of BeiDou stand-alone RTK positioning using mixed-receiver types demonstrate that ISTBs could seriously affect the integer ambiguity resolution performance and that a priori correction for these biases will dramatically improve the success rate.
