Finally, we implement the SCPS-TP/NC protocol and evaluate its performance by Network Simulator (Version 2). This article provides detailed process of protocol design, mathematical modelling and throughput analysis of the proposed SCPS-TP/NC. Combined with characteristics of Space Communication Protocol Specification-Transport Protocol (SCPS-TP) and advantages of terrestrial TCP/NC, an improved protocol referred to as SCPS-TP/NC, is proposed for space data communication. This article deeply studies the TCP/Network Coding (NC), which can effectively improve terrestrial wireless communication system throughput. However, the traditional TCP cannot be directly applied to space data communication.

has also announced that at some point he’ll set up a website and publish the findings and code that should make Starlink signal analysis easy for anyone with a readily available SDR receiver. Nothing too earth-shattering, but as a fun SDR hobby it definitely checks all the boxes. Even at this early time, some features of the Starlink protocol seem quite obvious, such as the division into channels and the use of guard periods. Some of the captured data seems to include the satellite ID system that ground-based user stations would presumably use to keep track of overhead Starlink satellites.įor the capturing itself, is using a second-hand dish for capture and a DIY SDR using KC705 FPGA-based hardware – which may have begun its life as crypto mining hardware – along with the usual assortment of filters and other common components with this kind of capture. One of these fine folk is, who has recently posted some early findings to r/StarlinkEngineering over at Reddit. This is also the case with people trying to analyze the communication setup and protocol which SpaceX is using with their Ku-band based Starlink satellites. Often, mere curiosity is sufficient to do something.
