The Asynchronous One-Way Range (AOWR) scheme was developed by the authors, and the results of the field radio tests conducted to date have been reported. Previous studies have assumed that simply resetting the clock in the AOWR scheme directly achieves synchronization. However, the iterative process has not been thoroughly examined, and the relevant indices have been anticipated without confirmation. This study investigates the synchronization process, derives the convergence properties associated with the AOWR scheme, and confirms, for the first time, the stability of iterative synchronization within the scheme. Practical applications for cis-lunar and near-Earth deep space navigation are highly expected.
