Ran the special snap file with a coordinate update interval of 2s on the 20m telescope control computer. The tracking error was < 5 arcsecond. Added 10dB attenuated to the system. After that, the DBBC2 had proper level of input signal. There were no known problems in the RadioAstron tracking experiment.

Onsala (Jun Yang at Mon Oct 26 06:59:16 2015) Success:

No Tsys measurement as the telescope was not under the control of FS computer.

Effelsberg (Uwe at Mon Oct 26 15:44:08 2015) Success:

No Tsys. Satellite signal was visible all time, but after the pointing was corrected at 14:20 UT the signal was even stronger.
