Athenoxat-1 QSL Hints Pointers to be able to track, receive, and decode data beacon of Athenoxat-1


Athenoxat-1, designed, fabricated, and operated by Microspace Rapid Pte Ltd, is a Nanosatellite following the standard of 3U cubesat size for Remote Sensing application, orbiting in equatorial orbit with 15-degree inclination since 16 December 2015. Her primary mission is to demonstrate High Resolution Night Vision imaging capability, and her secondary mission is to validate the capability of the Hardware and Software (CDH and ADCS) developed in-house. Included in her capability is the medium resolution and global view of the day imaging.

Athenoxat-1 has been equipped with several types of data beacon. As part of 2-year anniversary of Athenoxat-1, data beacon type 2 to 5 have been activated to allow Radio Amateurs community to obtain images produced by Athenoxat-1 herself. As a result of discussion between us and PY2SDR, data beacon type 3 has been modified as such that it is a medium-size image occupying up to 225 packets. Therefore, collective effort from the community is required in order to reconstruct the image and that is why this webpage is available.

Data beacon type 2 is a very small icon occupying only one packet. Type 4 is a thumbnail image occupying up to 21 packets. Lastly type 5, occupying only one packet too, is a text description for the image it follows. The latest ATX Decoder by PY4ZBZ can be used to reconstruct the images and text of these data. Scheduled QSL card transmission has been set to data beacon type 4 and thus the same ATX Decoder can be used.

We activate only either one of the data beacon type 3 or type { 2, 4, and 5 }. Today, it is the data type { 2, 4, and 5 } that is active. In the event of experiment, Athenoxat-1 will disable both Morse CW and data beacon.

Recommended Tools
  • Affordable USB-based RF receiver
  • UHF Antenna : cross yagi is preferred and optionally antenna rotor & controller
  • Satellite tracking software e.g. Orbitron by Sebastian Stoff or HAM Radio Deluxe
  • SDR# and Satellite tracking plugin for automatic Doppler Shift correction
  • High-speed Soundmodem by UZ7HO for decoding the audio data beacon
  • AGW OnlineKISS by DK3WN for producing .kss recording OR
  • Arapuca by PY2SDR to send automatically the decoded packets from the Soundmodem to the repository for community sharing, which especially useful for reconstructing large-packet image e.g. QSL card (to be further updated)
  • ATX Decoder by PY4ZBZ for constructing images of specifically beacon type 2, 4, and 5, including the scheduled transmission of QSL card
Acknowledgment We are grateful for the availabity of the following software that make it possible for the Radio Amateurs community
to track, receive, and decode data beacon of Athenoxat-1
