APOD, a chinese CubSat has been in Space since late 2015. One of its satellites carries a VLBI beacon. Since then, several efforts were undertaken to observe APOD.
We have had several attempts in observing APOD with the AuScope antennas in Hobart, Katherine and Yarragadee. Due to the long baselines, the tracks are relatively short. Our attempts here at the University of Tasmania to correlate the data have not really been successful so far. However, in November we will intensively try to collect more data. This includes an optimised tracking (continuous tracking should be possible with our antennas) and the observations themselves. Andreas Hellerschmied from Vienna will visit us and Tim Natusch from Auckland has also agreed to support us by providing the Warkworth antenna. Hoping to report on successful observations soon.
Friday, Nov 11, Mt. Pleasant observatory: tracking tests with Ho26m. Some tests using ISS signal; S-band beacon (2270) clearly detected, stable throughout track. Sattrack worked smoothly after drive PC reboot. Testing AzEl track for APOD of the next day. Found we can only do one side of the track (up to about 30 deg elevation).
Please find detailed descriptions of each experiment (including results in terms of multiband delays computed with fourfit) on the following pages:
