Voyager 1 adventures
summary
Describes two projects to receive and decode Voyager 1 signals using open-source tools (GNU Radio, Python). First, detection of Voyager 1 using a 6.1 m dish at the Allen Telescope Array (Nov 2020) and analysis showing that with stable frequency references, accurate Doppler correction, and multi-hour integration amateurs with smaller dishes might also detect it. Second, decoding Voyager 1 telemetry from 100 m Green Bank Telescope recordings (2015 and 2020), examining the spacecraft’s pre-CCSDS data format; all data and results are publicly available.
