A priori knowledge-free fast positioning approach for BeiDou receivers [PDF]

open access: yes, 2022
A Global Navigation Satellite System (GNSS) receiver usually needs a sufficient number of full pseudorange measurements to obtain a position solution. However, it is time-consuming to acquire full pseudorange information from only the satellite broadcast signals due to the navigation data features of GNSS.
