Receiving the Artemis 2 S-Band Carrier With a Wi-Fi Dish and Airspy R2

Thank you to Simone Spadino for writing in and sharing how he received the S-band carrier signal from the Artemis 2 Orion capsule from his home in Italy, using a simple one-meter Wi-Fi grid dish, an Airspy R2, an LNA, a filter, and a downconverter. Simone notes that his results show it is possible to receive the Artemis carrier signal with a small dish.

Artemis 2 may have already returned to Earth safely, but there are future missions planned for 2027 and beyond, so Simone's write-up serves as a great place to get yourself ready to receive those future missions.

Simone's write-up notes that perfect tracking with a rotator wasn't required because the Wi-Fi dish had a beamwidth of about 11°, so he was able to manually orient the dish every 10 minutes using an Android smartphone. On the first night, he achieved a carrier SNR of 5.5dB, and on the second night, 6.5 dB.
