摘要

Dual one-way ranging systems measure intersatellite distance with very high precision by combining the oneway range measurements from two satellites. This high precision is obtained by minimizing the oscillator noise effect, which is the main error source for microwave ranging systems. A key requirement for the dual one-way ranging system is the synchronization of the two one-way range measurement times, and this requirement makes it necessary to compute a high-accuracy clock solution. An optimal frequency configuration is proposed to mitigate the time-synchronization requirement. Numerical simulations demonstrate that the optimal frequency configuration becomes very effective when the clock offsets are not well known.
