CAMSAT announces mid-July launch with six U/V transponders

Alan Kung, BA1DU (CAMSAT CEO) recently sent AMSAT-NA a stunning press release, copied in full below:

CAMSAT orchestrated CAS-3 amateur satellite system is now nearing completion, six Chinese amateur satellites will be launched in mid-July,it includes different weight category satellites, consists of a 20 kg, three 10 kg and two 1 kg satellites. All six satellites are equipped with substantially the same amateur radio payloads, a U/V mode linear transponder, a CW telemetry beacon and an AX.25 19.2k/9.6k baud GMSK telemetry downlink are attached in each of the six satellites, each set of amateur radio equipments has the same technical characteristics, but operates on different frequencies of 70cm band uplink and 2m band downlink.

New Challenge Coin Premium for AMSAT Fox Donations

AMSAT is excited to announce that a new premium collectable is now available for qualifying donations to the Fox satellite program. AMSAT has commissioned a unique challenge coin for donors who have contributed at the $100 level or higher. This challenge coin is shaped as an isometric view of a Fox-1 CubeSat, complete with details such as the stowed UHF antenna, solar cells, and camera lens viewport. Struck in 3mm thick brass, plated with antique silver, and finished in bright enamel, the coin is scaled to be approximately 1:4 scale, or 1 inch along each of the six sides. The reverse has the AMSAT Fox logo.

10665294_827617400594275_1401063514767949235_nThe coins are scheduled for delivery just prior to the 2014 AMSAT Space Symposium, and will be first distributed to donors attending the Symposium. Coins will also be made available to qualifying donors that have contributed since the Fox-1C announcement on July 18, 2014 upon request. Donations may be made via the AMSAT website, via the FundRazr crowdsourcing app at http://fnd.us/c/6pz92/sh/561Zd, or via the AMSAT office at (888) 322-6728.

The Fox program is designed to provide a platform for university experiments in space, as well as provide FM repeater capability for radio amateurs worldwide. Fox-1A and 1C are set to launch in 2015, and Fox-1B (also known as RadFXSat) is awaiting NASA ELANA launch assignment. Further information on the Fox project can be found at http://www.amsat.org/?page_id=1113.

You may donate here via PayPal. Donations will be marked specifically for Fox-1C. Note that PayPal usually allows you to donate with a credit card, even if you do not have a PayPal account. However, PayPal requirements differ depending on your country. We have no control over this issue.

Space Symposium Auction Announced

Greetings Amateur Radio in Space Enthusiasts!

2014 AMSAT Symposium

2014 AMSAT Symposium

At this year’s AMSAT Space Symposium, we are trying a few new things and we hope you will enjoy them.  One exciting facet we are adding this year is an auction.  All proceeds from the auction will support AMSAT’s two major initiatives—the development and launch of the FOX satellite series and the ARISS program.

As we prepare for the auction, we are asking for your help in donating specialty items for auction (minimum value $100) that will attract symposium attendee’s attention and get them bidding up the item price.  If you have any items that are ham related (no boat anchors please), items of historical value, space related and/or autographed items, or even sports tickets or time shares, we would love to get your donations.  Think out of the box on this—what exciting things would you like to see in this auction?

If you have something to donate to the Symposium auction, please send an e-mail to Frank Bauer, KA3HDO, who will work with you on getting your item or items into the auction.   Frank’s e-mail address is ka3hdo at verizon.net

This auction, while adding a fun experience to the AMSAT Space Symposium experience, will also serve to keep amateur radio’s spirit thriving in space through its donations to FOX and ARISS.

On behalf of AMSAT, I thank you for your donations in advance.  And I encourage each of you to attend and participate in this year’s AMSAT Space Symposium to be held in Baltimore Maryland Oct 10-12.  For more information, see:

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
