| Abstract: |
| Aiming at user stations of a satellite position location and communication system, this paper described direct sequence spread spectrum system's signal feature, the main points of channel design,problems of pesudo-code synchronization and method of englneering design and accuracy analysis of distance measurement. Method of engineering design and computing formulae were given. Practical measurement results are identical with theoretical analysis. |
