VO-52 “Hamsat” end of mission

by

From an email to AMSAT-bb email list today:

Dear Friends,

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.

Although 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’

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. Rest in Peace.

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. Goel, Dr.

Shankara, Dr. T.K. Alex, Director-ISTRAC Shri. B.S. Chandrasekhar, scientific secretary Dr. Koteshwar Rao, Project Director-Shri. J.P. Gupta, Deputy project Directors, Mission Director-Shri. R.Suresh, Operations Director-Shri. Parimalarangan and each and every person directly or in-directly contributed.

At this point of time, we also thank AMSAT-India and in particular, late Shri. Nagesh Upadhyaya-VU2NUD,  Shri. B.S. Gajendra Kumar-VU2BGS, Shri.

Prathap Kumar-VU2POP, Air Commodore. Subramanian-VU2UV, Shri.  V.P.

Sandlas-VU2VP, Dr.R. Ramesh-VU2RMS, Shri. Nitin-VU3TYG, Mr. Williams Leijenaar PE1RAH and each and every member.

Pasted below is the message from Mr. R. Suresh, Mission Director:

HAMSAT, the first small satellite by ISRO has been Decommissioned after nearly a decade of service to the World Ham community.

A true masterpiece among small satellites, designed for one year mission life, but exceeded all expectations by serving for almost 10 years. A truly autonomous satellite, with “Zero maintenance“ in terms of Mission operations, it provided a springboard to test many new concepts such as BMU. LI-ion based power system, automatic Spin rate control and Auto SAOC for maintaining the Satellite attitude without any ground commanding.

HAMSAT known as “OSCAR-52” among the Amateur HAM operators has been very popular because of its high sensitivity receiver and strong transmitter. Indian Radio Amateurs on many occasions conveyed to us that they have been greatly honored to share the adulations showered on ISRO and INDIA by the International Radio Amateur for gifting this wonderful satellite “HAMSAT”.

I take this opportunity to applaud the HAMSAT teams at ISAC, ISTRAC and other centre for their efforts and  support, which has made ISRO proud among the HAM users across the globe.

AMSAT videos from Dayton 2014

by

Tom, K3IO, was the speaker at the AMSAT/TAPR Banquet at the Dayton Hamvention. In his talk, he remembers the many Elmers that helped him with his hobby and career.

Barry, WD4ASW and AMSAT President, gives an update on AMSAT, including changes to the BoD roster, regulatory issues, membership and finances.

As AMSAT’s new VP of Engineering and Fox satellite team leader, Jerry gives an update on the Fox-1 satellite, its design, milestones, and launch opportunities. He also looks ahead to Fox-1B, Fox-1C, Fox-1D, and Fox-2.

Howard, G6LVB, gives a fascinating look into the launch and operation of the FUNcube-1 satellite, and a tentative calendar of the next three FUNcube satellites.

Drew, KO4MA, reviews six operational amateur satellites, then previews another dozen amateur satellites that will be launched soon, or should be turned over to amateur use when their primary mission is completed.

Frank, KA3HDO, gives an update on Amateur Radio on the International Space Station, including the radios and antennas on board, the impact of funding changes at NASA, and the new Ham TV system.

EMike, KC8YLD, explains how K-16 education is key to the launches of future amateur radio satellites, and discusses the joint work of AMSAT, ARRL, and NASA.

In this brief video, Spence, WA8SME, shows the next version of the WRAPS rotor with circularly polarized antennas and discusses an updated broadband preamp that now includes an antenna polarity switch.

Special Thanks to Steve Belter, N9IP for recording and editing the videos from the Dayton Hamvention, making them available for those who couldn’t attend in person!

SPROUT microsatellite to launch 0305UTC May 24th with SSTV and digitalker

by

SPROUT is a 7.1 kg microsatellite set to launch on the JAXA ALOS-2 mission on May 24th at 0305 UTC from Tanegashima Space Center, Japan to a 654km sun synchronous orbit. Watch the launch live at http://global.jaxa.jp/projects/sat/alos2/index.html

This satellite is a project of Nihon University and will include some interesting amateur radio payloads and experiments, including CW telemetry, an FM digipeater, digitalker and message box, and live and preloaded SSTV pictures! Nihon University enjoyed previous success with SEEDS-II, aka CO-66.

Qatar ARS and AMSAT-DL announce Phase 4 satellite payload

by

A collaboration between the Qatar Amateur Radio Society, the Qatar Satellite Company, and AMSAT-DL has resulted in the announcement of a geostationary amateur radio payload aboard the proposed Es’HailSat-2 commercial satellite.

Due to be launched in 2016, the satellite will provide communications services to the Middle East and North Africa region from a position at 26 degrees East. Additionally, the satellite will include two 2.4 GHz to 10.45 GHz transponders dedicated for amateur use. One transponder will be approximately 250 kHz wide, and will be for traditional narrowband modes such as SSB and CW. The second will be 8MHz wide and designed for experimental DVB and data modes. Coverage is expected over the entire footprint.

While this payload will not service North America, the project is an important step into high orbit, and may open the door for additional opportunities in other orbital positions.
