Delfi-n3XT Transponder test

Posted on by

Coming, Delfi-n3XT Linear Transponder tests

Delfi-n3Xt Earth

We are going to test the transponder functionality of Delfi-n3Xt this week. I have to be honest that this functionality was implemented last minute on the satellite and was only tested briefly in a non-representative setup. I therefore estimate the chance that it will work at 50/50.

Our first series will be at:

  • Thursday 20-02-2014 at about 10:50 UTC
  • Friday 21-02-2014 at about 9:50 UTC
  • Friday 21-02-2014 at about 11:25 UTC

After a few initial tests, and provided that it works, you are free to use the transponder for communication. We will leave it in this mode for the remainder of the sunlit part of the orbit, so only in Europe and Africa it is possible to use this mode for now. If successful we will turn on the transponder more often and for longer periods of time such that everyone can enjoy it.

Frequency:

Uplink 435.530 – 435.570 MHz LSB Linear transponder
Downlink 145.880 – 145.920 MHz USB Linear transponder (inverting)

NanoRacks first cubesats are deployed

Posted on by

The first of the Planet Lab Dove CubeSats were deployed from the ISS on February 11, 2014 about 0831 UTC, astronaut Koichi Wakata, KC5ZTA successfully deployed the first of the 33 CubeSats that were launched from the Wallops Flight Facility, VA to the International Space Station (ISS) in the Cygnus freighter on January 9.

The first two of the Flock-1 constellation of 28 Dove CubeSats made by Planet Labs were deployed at about 0831 UT, it is thought there were another two Dove CubeSats deployed at 1241 UTC.

In addition to the 28 Planet Labs CubeSats there are four amateur radio CubeSats – LituanicaSat-1, LitSat-1, ArduSat-2 and UAPSat-1 as well as a 915 MHz CubeSat SkyCube.

The below image is a Orbitron view screen overview with satellites that I am trying the track and decode at the moment. After the last launches, there are a lot of them.

Decoded with Maspro UHF yagi, SSB preamp, FUNcube Dongle Pro+, SDR# and DUDE Delfispace ground station telemetry decoder. After that the raw packet data was used as input for one of the nice decoder software packages from Mike DK3WN.

The latest versions of the software packages from Mike come with a save function that makes a transparent screenshot from the software output. A very nice new feature. Thanks Mike.
