| Pseudo Code Ranging Method and Precision Analysis of Aerospace Spread Spectrum TTC&DT Systems |
|
| () |
| Abstract: |
| The operation principle of coherent pseudocode ranging and noncoherent pseudocode ranging in spread spectrum TTC&DT systems is introduced.It is proved that the errors of the ranging systems adopting two systems respectively are the same if the distance data sampling time of satellite is in strict accordance with that of ground station.The analysis method of pseudocode ranging error is also given. |
| Key words: aerospace TTC&DT system,spread spectrum technology,pseudocode ranging,precision analysis |
