I’m Zac Manchester KD2BHC, a graduate student in Aerospace Engineering at Cornell University. Over the last several years a few collaborators and I have designed, built, and tested a very tiny and inexpensive spacecraft called Sprite that can be built and launched into low Earth orbit for just a few hundred dollars each!
The CubeSat Project Team in the University of Khartoum have made available software to decode the telemetry beacon of the new Amateur Radio satellite built by the SRM University.
The Telemetry Decoding Software was developed by University students for studying the University of Khartoum CubeSat (KN-SAT1) telemetry data. It has now been modified to handle SRMVU data

Good signals received from SRMSAT and JUGNU

The Jugnu team say the continuous stream of satellite beacon reports from Radio Amateurs across the world surpassed all their expectations. The team welcome further reports.

I’m the system engineer for the Jugnu nanosatellite project. This is the nanosatellite which is more generally known on this list as JNU, since that was the identifier sent along with the TLE. I’ve been lurking on this list for the past couple of years, ever since we started working on the nanosatellite. I did learn a lot from occasionally perusing through the posts here. Not being a licensed HAM myself, I apologize for intruding into your space here today.
On behalf of the entire Jugnu team, I’d like to thank all of you for the beacon reports you’ve sent our way, both on the list as well as through Mani (VU2WMY). Its been a long couple of years on the project, but the last few days have been a much more intense roller coaster ride. The continuous stream of beacon reports from across the world surpassed all of our expectations, and were the mainstay of our emotional support while we were having difficulties recieving the beacon ourselves. If I do get to meet any of you in person, the beer’s on me.
The telemetry gathered by HAMs across the world has been extremely useful in our analysis of the spacecraft’s condition. I hope to be able to release, at least partially, the details of the format for the beacon string in a couple of days. In the meanwhile, we welcome any additional telemetry that you can send our way. Even information about the AOS/LOS has been very useful in trying to figure out where exactly the satellite is.
NORAD / celestrak has released 5 TLE’s tagged with the PSLV C-18 launch (2011-058<A-E>). We arent yet sure which one, if any, is Jugnu. We do know that SRMSat is one of the cluster of 3 objects (B,C,D). We’ve been able to recieve our beacon when we attempt to track C, but the signal strength is low and we generally see it clearly only near AOS. Due to reasons I’m probably not allowed to discuss in public, we have reason to believe that Jugnu is moving away from the other objects (SRMSat, VesselSat, and until later today, MT) at a velocity of approximately 1.5 to 3 meters per second since separation from LV. We expect this velocity to be tangential to the orbit. If you’re trying to track Jugnu, I would suggest that for the moment, C is a good starting point, and it may be better to track a little ahead of
it. We will be trying to do the same in some of the later passes ourselves.
In the case of SRMSat, we’ve had good signals at object B until earlier today, but we think that C did a better job of it in the last decent pass we had earlier this evening, about 6 hours ago.
I’d be more than delighted to try and answer any questions you may have about Jugnu, so please feel free to contact me on or off list if you would like to know more about it.
Thanks and Regards,

The AMSAT-NA 2011 Space Symposium will be held on Friday, November 4-6 in San Jose, California. This year’s Symposium coincides with the celebration of the 50th anniversary of OSCAR 1, the first Amateur Radio satellite.
There will be two talks on the AMSAT-UK FUNcube Dongle VHF/UHF Software Defined Radio (SDR) at the BAA Radio Astronomy Group (RAG) meeting on Saturday, November 12 at 10:30am in The Humfrey Rooms, Castilian Terrace, Northampton, NN1 1LD.
• Tony Abbey will talk about his experiences of using the AMSAT-UK FUNcube Dongle – a software defined radio receiver. Subject to orbital timings, he will be demonstrating reception from a satellite as it passes overhead using a hand held antenna and laptop.
• Dr David Morgan will describe how the FUNcube Dongle raises the prospect of amateurs being able to put together a low-cost radio telescope.
Tickets for the main event are £15 (£12 for BAA members) to include tea, coffee and a buffet lunch, or £10/£7 without the lunch. To obtain a ticket see http://www.britastro.org/radio/

JUNGU received by N8MH on an AMSAT-UK FUNcube Dongle SDR
Radio Amateurs have been reporting good signals on 437.425 MHz and 437.275 MHz from the new Amateur Radio satellites SRMSAT and JUGNU.
Unfortunately due to the 20 degree inclination of the orbit hams in the United Kingdom are unable to hear them.
Mark Hammond N8MH reports on the FUNcube Yahoo group that he has been using his AMSAT-UK FUNcube dongle Software Defined Radio to receive signals from JUGNU.
