A report on the PI9CAM website forwarded by PE0SAT describes how Triton-1 was recovered with the help of the 25 meter dish from PI9CAM.

Triton-1 was launched on a Dnepr on November 21, it has a 435/145 MHz FM to DSB transponder which is expected to be available for amateur radio use about 3 months after launch. The PI9CAM report says:

On November 29 we had an exciting day at PI9CAM.

We were asked to rescue a satellite!

On November 21, 14 satellites were launched. One of them is TRITON-1, built by the Dutch ISIS group.

First all was OK, but when a transmitter was switched on to keep the temperature on board high enough something went wrong. Harmonic noise of that transmitter desensed the receiver in such a way that the command station could not get any commands into the satellite….

It’s rather normal that satellite software resets every now and then. But it appeared this satellite software was very stable. Not one reset took place……

To try to regain command over the satellite PI9CAM was asked to help. The link budget predicted we might just be able to ‘cut through’ the noise with our 25 m dish and 400W on 70 cm.

So people from ISIS and CAMRAS met in Dwingeloo at PI9CAM in the early morning of November 29.
Mr. Murphy decided to join us that day….
First we found out that we connected the wrong cable up in the focusbox when we last worked on the frontend.
So we had no power on 70 cm….
It was raining and there was strong wind but the only way to get this right was to go up to the focusbox at 15 m high with the elevator….
We worked as fast as we could to prevent much water going into the focusbox.
I have never been so wet…..
But we managed!

Due to this we missed the first good pass of the satellite….

During the second pass the wind was really strong and probably because of that something went wrong when the dish started tracking the satellite at AOS. It more or less was blown into maximum safety position. This can only be reset by doing manual elevation. So we lost the second pass and two people got very wet by elevating the dish manually. But again we managed….

The third pass was only available at 21.00 so we had a lot of time to test tracking and to play with the freshly installed satellite tracking software. Even a few bugs were found and removed going through the software.

At 21.00 we were ready for it and everybody was very tense….
As soon as the satellite was above our TX limit of 10 degrees elevation we started transmitting. After 10 seconds we received good news from the ISIS ground station. We successfully switched off the transmitter of the satellite and the groundstation had control over the satellite again!

Everybody was very happy! We even had some champagne to celebrate this successful collaboration!

And we were all very proud of ‘our’ 57 year old and restored dish. Old, but still going strong!

73!

A United Launch Alliance Atlas 5 rocket is set to launch from Space Launch Complex 3-East, or SLC-3E at Vandenberg Air Force Base on California’s Central Coast. As well as a classified satellite for the US spy satellite agency the National Reconnaissance Office it will carry 12 CubeSats four of which will have amateur radio payloads. Justin Foley KI6EPH writes:

We are pleased to announce the launch of 12 CubeSats, currently scheduled for Friday, December 6, 2013 at 0713 UT from Vandenberg AFB in California, USA. Several of the CubeSats are carrying beacons in the amateur frequencies and we invite all who are able to track to participate.

For more information please keep an eye on http://spaceflightnow.com/atlas/av043/status.html and http://cubesat.org/index.php/missions/upcoming-launches/134-l39-launch-alert

CAT: Launch a Water-Propelled Satellite into Deep Space

Benjamin Longmier KF5KMP and James Cutler KF6RFX of the University of Michigan have launched a Kickstarter to raise funding to develop a CubeSat Ambipolar Thruster (CAT).

CubeSat Ambipolar Thruster (CAT)

CubeSat Ambipolar Thruster (CAT)

The project’s Kickstarter page says:

Space exploration has traditionally been expensive, many spacecraft launched today are the size of a truck and can cost over $1 billion dollars. CAT will be tested on a CubeSat, a small satellite the size of a loaf of bread. CubeSats cost 1,000 to 10,000 times less to develop and launch than conventional satellites. As scientific and commercial space technologies get exponentially smaller, it becomes easier (and less expensive) to place small but powerful sensors on a CubeSat platform. The CAT engine can propel this miniaturized equipment to exciting new locations previously unreachable at such a low price.

Traditional university research funding starts with seed data, a small seed grant, a government grant and a large number of gates to go through over many years. We’d like to leverage Kickstarter funds to compress that timeline and go from initial seed data to flight in about 18 months, a much faster time scale than is possible with traditional grants. We love the idea of “Citizen Explorers” helping fund this project and are excited to have our backers be part of the journey.

While we have obtained some external funding, this mission may never happen without your help. Research funding is notoriously slow and filled with red tape. Technology demonstration missions can take over ten years to go from concept to launch. We want to do more faster, getting CAT from the drawing board to space in record time. With your help, we will be assembling everything into one compact thruster unit and testing integrated components in the lab, then in Earth orbit. If we reach stretch goals, we could be testing CAT in interplanetary space at a destination of your choice!

Our base funding goal of $50,000 is enough to add specialized equipment to the satellite to observe the plasma plume ejected by the CAT engine. Integrating a high-resolution camera and associated subsystems is critical to validate our theories on plasma flow along a magnetic nozzle and complete our test matrix when CAT is on-orbit. Because this is an entirely new type of engine, we need a camera in order to directly observe how the super heated plasma follows the magnetic nozzle and then detaches to create thrust. Without a camera we can’t know precisely when the plasma is being created. Basically, we need to see the engine actually creating plasma to verify our assumptions. On Earth it’s easy for us to observe the plasma during testing, but in space it’s much more difficult.

Trailblazer and DragonSat – Help Requested

DragonSat

DragonSat

Craig Kief KE5VSH posted this on the AMSAT Bulletin Board (AMSAT-BB):

Jin KB3UKS and I launched two CubeSats a week or so ago. The first is Trailblazer (mine) and the second is DragonSat (Jins). Trailblazer is from the Configurable Space Research at the University of New Mexico (KE5VSH) and DragonSat is Drexel University.

Our problem is that we haven’t heard from our satellites yet.

There could be a variety of different reasons. First, the satellite didn’t survive delivery.  Second, our antennas didn’t deploy or third, we have poor ground stations.  As you can imagine, I am hoping for the third. I am pasting the TLE which is openly available on space-track and Celestrak in this email. It is very close (I believe) to our birds.

Trailblazer

If you have a chance, could you please keep your ears open in case you might hear us.

Please email any packets for Trailblazer to myself at craig.kief<at>cosmiac.org and for DragonSat to Jin Kang KB3UKS at kang<at>usna.edu

Thanks again most sincerely,

Craig KE5VSH

Live Video Streaming from the ISS

The N2YO satellite tracking website provides live video streaming from the International Space Station (ISS) alongside a track showing the position of the ISS over the Earth.

The Ustream video from the station is available only when the complex is in contact with the ground through its high-speed communications antenna and NASA’s Tracking and Data Relay Satellite System. During “loss of signal” periods, you will see a blue screen. Since the station orbits the Earth once every 90 minutes, it sees a sunrise or a sunset every 45 minutes. When the station is in darkness, external camera video may appear black, but also may provide spectacular views of city lights below.

The US segment of the ISS uses a data link in Ku band to connect to a NASA server. The link provides a data rate of 10 Mbps download and 3 Mbps upload available about half the time through a network of ground stations.

In October 2012 the first laser communication link with the Russian segment of the ISS was established paving the way for higher speed broadband links to the ISS in the future. Read the RIA Novosti article in Google English.
