Abstract
Inter-satellite link (ISL) plays an important role in GNSS. First inter-satellite clock offset is analyzed, which is used for evaluating the on-board clocks. Then, the feasibility of evaluating on-board atomic clock is discussed which is produced by ISL data. After building the model of evaluating inter-satellite clock offsets and simulating on-board clock offsets, the on-board clock performances are evaluated by polygon hat method. The result is compared with precise clock offset. The conclusion shows inter-satellite clock offset can be used for evaluating performance for BDS-3 on-board atomic clocks which the frequency stability is reaching E-15.
