[amsat-bb] DOSAAF-85 transponder activation

[Nico Janssen]

The new amateur payload DOSAAF 85 appears to work very well.
Doppler measurements confirm that it is indeed object 44909,
2019-096E. The satellite identifies itself as "RS44" (i.e. Radio
Sputnik 44) on its CW beacon on 435.6043 kHz. The passband is
about 63 kHz wide. It may also have a downlink between 2400 and
2485 MHz. The frequencies of RS44/DOSAAF 85 have not been IARU
coordinated. The satellite is in an elliptical orbit with a perigee of
1175 km, an apogee of 1511 km and an inclination of 82.5 degrees.

The payload is apparently attached to the Breeze-KM upper stage of
a Rokot launch vehicle that launched three Gonets satellites on
December 26, 2019. It was originally expected to launch in 2015.
It is based on the Yubileiniy platform.
