VO-52 “Hamsat” end of mission

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.

R,SURESH

UKube-1 was successfully launched and deployed today from the Soyuz-2-1B/Fregat-M launch vehicle as a secondary payload. The launch took place as planned at 15:58 UTC from Baikonur in Kazakhstan. The primary payload was Russia’s Meteor-M2 weather satellite. Additional secondary payloads (according to eoportal.org) included:

  • Baumanets-2, a technology microsatellite (~100 kg) of BMSTU (Bauman Moscow State Technical University)
  • Monika-Relek (or MKA-PN2), a Russian microsatellite (solar and magnetosphere research)
  • Venta-1 / V1-QSPnP1 (V1-QuadSat-PnP-1) the first nanosatellite (7.5 kg) project of Latvia built by LatSpace SIA of Ventspils.
  • TechDemoSat-1 of SSTL, UK with a mass of ~160 kg
  • DX-1 (Dauria Experimental-1) of Dauria Aerospace, Russia’s first private microsatellite with a mass of 22 kg.
  • SkySat-2 of Skybox Imaging Inc. of Mountain View, CA, USA, a commercial remote sensing microsatellite of ~100 kg.
  • AISSat-2, a nanosatellite with a mass of 6.5 kg of Norway.

UKube-1 is a 3U cubesat and carries a FUNcube educational beacon and linear transponder similar to AO-73 (FUNcube-1). Beacon signals were heard soon after launch by the UKube team at 19:16 UTC.

Frequencies in use by UKube-1 include:

  • 145.840 Primary telemetry downlink CW or 1k2-9k6 BPSK
  • 145.915 FUNcube-2 telemetry 1k2 BPSK
  • 145.930-145.950 FUNcube-2 transponder downlink, 435.080-435.060 uplink
  • 2401.0 S-band downlink (QPSK-OQPSK)
  • 437.425-437.525 myPocketQub spread spectrum

Transponder and data downlinks operation will be variable during checkout and early operations. Check ANS, http://funcube.org.uk/, and http://amsat-uk.org/ for the most recent updates.

 

Dnepr Launch with 37 satellites on June 19th

ISC Kosmotras has launched another Dnepr from the Yasny facility in Russia. This launch carried an astounding 37 individual satellites to orbit, eclipsing the record set just last November by the previous Dnepr launch (including AMSAT-UK’s FunCube-1 aka AO-73). The Dnepr is a converted R-36M ICBM, now retasked to launch satellites instead of nuclear warheads. Launch was Thursday, June 19th, 2014 at 19:11:11 UTC.

While a complete listing of the satellites onboard can be found at http://www.zarya.info/Calendar.php and http://www.spaceflight101.com/dnepr-launch-updates—2014-cluster-launch.html , we have compiled a list of the amateur and amateur related payloads below:
