Summary: | The technique of intra-satellite communication networking and asynchronous ranging for autonomous forma-tion flyer(AFF) were researched. The hybird FDMA/CDMA mode was developed for AFF communication networking,and precisely ranging & time synchronization was performed by bidirection Asynchronous transfer frame of CCSDS proximity-1 protocol via intra-satallite microwave link in AFF. The principle of two-way noncoherent ranging mode about direct sequence spread spectrum(DSSS) was presented for intersatallite ranging/time synchronization in AFF FDMA/ CDMA networks,concerned equations were constructed and two iteration compupting algorithms were derived. Then,the ground experimenting systems for studying and testing the performance of intra-satallite communication and two-way noncoherent ranging/time synchronization were presented with many experiment results and analyzing. Ex-periment results show that the satisfied performance is obtained. |
