Catch the Last ARISSat-1 Telemetry

ARISSat-1Now that the submissions are complete for the Chicken Little Contest, AMSAT is announcing a new contest: Catch the Last ARISSat-1 Telemetry. With luck, we will have real time data to go along with the final reentry. While telemetry sent by e-mail is valuable and requested, the contest will be judged solely on data sent through the official ARISSatTLM programs directly to the Internet telemetry server.

How do I enter? Simple. Just submit ARISSat-1 telemetry over the Internet using either ARISSatTLM telemetry program. You can use the PC version or the MAC version of ARISSatTLM. You are automatically eligible.

Are there separate categories for entrants? No.

How is the winner determined? The call, or name, in the last block of data received by telemetry server wins.

How will the winner be announced? Via the usual AMSAT News Service, and on the Chicken Little Contest site.

If ARISSat-1 fails sometime before reentry, does it count? Yes! Engineering data is essential input for future projects!

What do I get if I win? A certificate in PDF format suitable for framing, and the gratitude of the ARISSat-1 team.

In short, just keeps those telemetry blocks flowing!

Remember: you can see the latest ARISSat-1 telemetry at ARISSat-1 realtime telemetry

RAX-2 is OBJECT E

Posted on by

A good explanation from DK3WN on how to determine what TLE data belongs to what Satellite.

Based on the latest cubesat TLEs we have now three groups of objects (B+C+D, E, F+G). The first group are the 1U cubesats – they are only a few km apart. In 13 sec distance is RAX-2. I think F and G are the DICE sats.

Elena-III All TLE 02-11-2011

A simple way to determine the TLE, Take one beacon frequency – in this case 437.435 MHz (belongs to RAX-2). Then I calculated all the doppler frequencies for all objectes on a high 66 deg elevation pass. If the doppler = 0 then we have TCA. In this way you can calculate the distance between the TCA of each satellite.

Elena-III All TLE Doppler correction

You can see the 13 sec difference of RAX to to the first group (E1P, MCubed and AubieSat-1)

RAX-2 Zero 02112010 11:13UTC Pass

Take a look at the spectrogram – the horizontal yellow line is the center frequency of 437.345 MHz and the vertical one is the calculated time for RAX-2. And as chance would have it – we have a packet there. If you take the middle frequency of this 9k6 packet -> it all comes to one point.
