摘　　要：对共视法和综合法的GPS时间比对得到的两地协调世界时的时间同步精度进行了比较。两种方法各有特点 ,都有实用价值。严格共视的GPS时间同步精度为 5～ 10ns ,不严格共视的GPS时间同步精度为 10～ 2 0ns,综合的GPS时间同步精度为 6～ 12ns。The synchronization precision of UTC at two sites determined by common-view and synthesized GPS time methods were compared. All the methods are of their own characteristics and are practicable. The precision of the GPS time synchronization for strict common-view method, non-strict common-view method and synthesized method is 5～10ns, 10～20ns and 6～12ns, respectively.
