I put the TLE from below into a satellite tracking program and the anticipated track over the past 12 hours or so can be viewed at
Of course, the satellite isn't on orbit yet, but I thought a preview of the TLE-predicted track might prove interesting.

- Lompoc High School Students Experience ARISS Contact
On Thursday, September 29, students attending Lompoc High School in Lompoc, California connected with on-orbit astronaut Mike Fossum, KF5AQG via an Amateur Radio on the International Space Station (ARISS) contact. Fossum fielded over ten questions before the ISS went over the horizon. Students who participated in the contact are involved in Lompoc's STaRS (Space, Technology and Robotics Systems) Academy. The event highlighted students‚ studies covering space flight, the space environment, orbital motion, ground tracking, life support systems and rockets. The Santa Maria Times posted an article about the experience: http://santamariatimes.com/news/local/education/talking-to-an- astronaut-in-space/article_b85f7212-eb40-11e0-a23f-001cc4c002e0.html

Hello Jan,
Yes, the battery is dead. There are no transmissions when the satellite is in eclipse. Also, after ARISSat-1 re-enters sunlight, there is a 15 minute delay from a built in timer before transmissions begin.
Here in the US, we don't currently have any useable windows! It's either in eclipse, or too close to it for the transmitter to come on overhead.
The orbit will precess in the next couple of weeks and we'll again have some useable time.

Are there stations in Europe that receive ARISSat-1 telemetry or other data? I tryed last week and yesterday evening but nothing was received.
Are the batteries completly drained and therefor no activity when the Sat is in the dark :-)

Hello,
I'm launching a project in my spare time that some AMSAT members might be interested in. I'm a graduate student in Aerospace Engineering at Cornell, and I've been working on a ChipSat/Femtosatellite called Sprite for the last several years. I want to launch a CubeSat full of Sprites into low Earth orbit to demonstrate their viability in space. I'm raising money to build the hardware via the Kickstarter website (kicksat.org). Donors who sponsor a sprite will get to name it and specify the text that it will transmit. A group or club can also sponsor a fleet of Sprites together.
I'm doing this to try to get more people involved in spaceflight. I want to make it easy enough and cheap enough so that anyone can take part.
Please check out my page on Kickstarter for more information - kicksat.org
Thanks, Zac Manchester

Many thanks Tim for your comments. From what you've said it sounds like a faulty motor. In the ones you've repaired have you been able to determine the cause of motor over heating?
The problems I've had in the past have always been due to water getting into the units.

The common failure of the motor windings is caused by heat which causes the enamel coated wire to breakdown. When the enamel breaks down an inner winding short results.
I have successfully rewound motor windings on these rotators just to say it could be done, but it takes some work (not recommended).
I have never seen one of these motors with an open winding. The failure mode on the 8 that I have repaired were always enamel insulation breakdown as a result of overheating.

I wonder if this is a known fault. Recently the fuse on my G5500 blew. The problem seems to be a short on one of the motor circuits.
Checking the DC resistance at the control end, the resistance of one winding is 1.2 ohms, whereas all the other windings are 4.6 ohms.
I could understand a motor burning out and going open circuit, but a short circuit seems less likely. I'm wondering if it could be a short on the cable at the rotator end, where it is subject to much bending. There's about 15 metres of cable.
Any thoughts would be much appreciated. Unfortunately, at the present time I'm not able to inspect the rotator. It's stuck in the horizontal position, so I will still be able to use the antenna for low elevation passes.

Interesting idea Zac, but I have a few questions.
Will each Sprite have it's own frequency?
Since these Sprites are operating in the Amateur satellite bands, how will you license them?
How will you handle the frequency coordination of these transmitters?
