GPS triple-frequency undifferenced and uncombined precise orbit determination with the consideration of receiver time-variant bias
TL;DR: Results imply that the precision of orbits and clocks can be improved with observations from the third frequency added, and a triple-frequency (TF) uncombined (UC) POD method of GNSS satellites is developed.

A mixed multi-frequency precise point positioning strategy based on the combination of BDS-3 and GNSS multi-frequency observations
TL;DR: In this paper , a mixed multi-frequency PPPP solution strategy is proposed based on a combination of BDS-3 and GNSS observations, where the inter-system bias parameter and the stochastic model are introduced into the function model; and finally, the mixed PPP solution and its software are developed and verified by three groups of experiments.
