Abstract实现小卫星编队飞行,在测定小卫星之间的距离的同时,还必须进行星间科学实验数据的交换。为了尽可能降低设备复杂度,本文研究了一种测距、数传一体化调制方式的调制解调原理,通过Simulink仿真分析得到了GMSK+PN信号在不同测距调制度条件下的数传误码率。经过分析GMSK+PN信号的特性,给出了GMSK+PN信号的信道估计方法和一种有效的测距、数传一体化解调算法。
Other AbstractFor the small satellites formation flying, the distance between satellites must be determined and an adequate inter-satellites communication medium must be used to transmit the science data. In order to minimize device complexity, this paper studied a system capable of simultaneously transmitting high rate telecommunication and ranging. through simulations by Simulink in different ranging modulation index, obtained the bit error rate of telecommunication data. By analyzing the characteristics of GMSK+PN signal, an effective demodulation scheme for GMSK+PN is developed by this paper.
