Abstract

A dual one-way ranging system (DOWR) provides very high precision range measurements between two carrier phase transceiver-receiver systems by combining the one-way range measurements from each system. A key requirement for the DOWR system is the synchronization of the two one-way range measurement times, and this requirement makes it necessary to interpolate the raw one-way phase measurements toward a common epoch. This interpolation process may degrade numerical accuracy under large time-tag offsets. This study proposed a new interpolation process to reduce the degradation. Numerical simulation analysis was performed to validate the performance of the proposed method.
