This evening a new attempt to decode FUNcube-1 (AO-73) with the latest decoder from Mike DK3WN. I used Dashboard version 848 and saved a binary file. After the pass I used that file as a input for the new decoder. Below the results, look awesome.

Goodbye HAMSAT VO-52

Posted on by

Source: Amsat-BB

It is a sad day, one of my and many Ham Radio Amateurs favourites stopped working after 49,675 orbits.

With heavy heart, I sadly convey, that our little angel ‘HAMSAT VO-52’ would no more be able to offer her services to the ‘Amateur Radio Fraternity. HAMSAT VO-52 succumbed in Space on 11th July 2014, while she was on her 49,675th orbit, due to the failure of on-board lithium ion batteries that have met their end of life.

VO-52 PreFlightAlthough her desires were to be at work with other systems and sub-systems working normal as per the latest telemetry received, the on-board computer recurring to ‘Reset’ mode due to the failure of batteries is preventing her to do so. Hence, it is decided not to expect any more meaningful and reliable services from HAMSAT VO-52.

Since 11th July, every best possible effort has been put in by the spacecraft controllers here in ISTRAC Bangalore to revive her back to life and to help her with work load, so she won’t be swamped when she returns, but with no luck. Though it is hard, the HAMSAT VO-52 designers and controllers insist that the time has come to let the little angel free in space to go drifting on her own from their care and custody.

Thus, today 21st July 2014, ISRO have decommissioned ‘HAMSAT-VO52’
officially.

We all here in ISRO do definitely hope that ‘HAMSAT VO-52’ worked tirelessly and was a good friend to the ‘Amateur Radio Fraternity’ around the World. We are sure that HAMSAT was loved by all who worked through her. Though, we are deeply saddened by the loss of HAMSAT VO-52, but she will never be forgotten and far from our hearts, minds and memories.

HAMSAT VO-52 will always be remembered by all of us here in ISRO as one of the greatest satellites of ours.

Dear ‘HAMSAT’, looking at the sky, we all say ‘Good Bye’ to you. You’ll be greatly missed.

Nevertheless, at this point of time, on behalf of the World Amateur Radio Fraternity, we thank each and everyone who contributed to the great success of ‘HAMSAT’.

Particularly, our sincere thanks to the Chairman ISRO, Dr. K. Radhakrishnan, past chairmen Dr. Kasthurirangan, Dr. G. Madhavan Nair, Director-ISAC Dr. S.K.Shiva Kumar, past ISAC Directors Dr. P.S.
