| 摘要: |
| 本文对高级在轨系统（AOS）提供的等时性业务进行了深入的研究，讨论了利用AOS等时性业务实现伪码测距的可能方案。经过分析比较，得出利用插入业务实现伪码测距是目前条件下最好的方案，并通过实验从原理上验证了该方案的可行性。 |

| () |
| Abstract: |
| In this paper, isochronous service of Advanced Orbit System (AOS) is researched, and the possible schemes for implementing pseudo-random code ranging by using isochronous service of AOS are discussed. The scheme of using Insert Service is analyzed specially and it is proved to be effective by principle experience. |
