Starlink in your backyard: A DIY approach to satellite monitoring and data analysis

Abstract This work provides a detailed walk through the design, construction, and operation of a DIY monitoring station, emphasising its affordability, accessibility, and ease of use. The station leverages readily available components, including software defined radio (SDR) receivers and a Raspberry Pi. These tools allow for constant 24/7 monitoring and automatic storage of band usage and the detection of Doppler-shifts in the satellite beacons, providing valuable data for analysis. Using this DIY setup can lead to indications of power levels and beam shapes of the Starlink satellites and user link strategy. Additionally, an experimental interferometer mode is being implemented, further expanding the capabilities of this home-based monitoring station with direct positional information.
