论文摘要
我们开发了一种用于在10.7至12.7 GHz频段中Starlink下行信号的盲信号识别的技术，并详细介绍了信号结构的详细图片。重要的是，本文提供的信号表征包括信号中嵌入的同步序列的确切值，可以利用该序列产生伪造测量值。对信号的这种理解对于新兴的努力至关重要的是，尽管它们仅专为宽带互联网提供，但仍寻求双重用途的星条信号以定位，导航和时间安排。
We develop a technique for blind signal identification of the Starlink downlink signal in the 10.7 to 12.7 GHz band and present a detailed picture of the signal's structure. Importantly, the signal characterization offered herein includes the exact values of synchronization sequences embedded in the signal that can be exploited to produce pseudorange measurements. Such an understanding of the signal is essential to emerging efforts that seek to dual-purpose Starlink signals for positioning, navigation, and timing, despite their being designed solely for broadband Internet provision.
