T+3 days – Update

by on November 24, 2013

The FUNcube-1 spacecraft was switched to its nominal “autonomous” operating schedule around midday yesterday.

This schedule has:

High power telemetry only when in sunlight (also known as “Educational” Mode) and

Transponder with low power telemetry when in eclipse (also known as “Amateur” Mode)

This switching is controlled automatically by the the magic in the CCT (Command, Control and Telemetry) subsystem on board.

We do not plan to change this operating schedule in the immediate future, unless we have to!

We have enabled some new Fitter messages today and monitored, with great interest, the telemetry that has been contributed by more than 100 stations around the world and is now displayed and stored in the Data Warehouse.

We cannot over-emphasize just how important this data is to the FUNcube team in helping us build up a good knowledge of the operating status of the spacecraft as it orbits the earth.

Please please keep it coming in and if you know of anyone who could set up some simple, automated, groundstations in some of the more remote locations then please encourage them to do so for us.

The AO73- FUNcube-1 Telemetry Beacon and Transponder Passband as seen by Mike DK3WN on 23/11/2013

We only have “Whole Orbit Data” for a few channels so we will be relying on all the remote data we can gather.

From reports that we have seen there have been many successful QSO’s using AO73 in the last 24 hours and there have been many reports of strong signals and smooth sounding audio. We are very grateful for your observations.

We have not received any new keps and are, ourselves, still using 2013-066B although these appear to be a little late. We hope to get more news on this from the space tracking experts shortly.

Thank you for all your support!

    Hi Graham

    Thanks to you all for doing such a great job. I’m using the tle suggested by Simon for his SDR console with my FCDproplus – looks slightly different from the 2013-066B numbers, but is also best part of a minute late – on the directly overhead pass yesterday, the doppler wasn’t corrected at all well. Good SSB reception last night of 2e0sql amongst others, and some strong CW sigs. Using a hand held 4 ele yagi indoors trying to avoid nasty pickup from my pc – sometimes I just prop it up on end pointing straight into the sky – works for a few passes. Shame my UHFSDR rig was playing up this morning so I couldnt talk to you on the 80m net.
    best wishes

    G’day team, what locations are missing? Here downunder, ZL1AOX and VK5HI have the antipodes well covered.

      Hi Ben,

      Thanks for the comment!
      Yes over Australia and New Zealand, also Southern Africa and South America we are fine but I have been watching some of the tracks today. There was one where we had no-one between the west coast of America and Central Europe. So if we could find some willing volunteers in central/west Africa, Antarctica, any island in the Pacific, Indian or Atlantic oceans, and perhaps Greenland or Svalbard or Alaska to the north- that would be fantastic. Sorry for the long shopping list.
      cheers

  5. Hello from Lauriston Girls’ School in Melbourne. Our first data upload took place just before midnight UTC on launch day, Thursday November 21st. We received the two morning passes today (elevation 18 degrees and 35 degrees) using a hand-steered yagi mounted on a camera tripod. One student moitors Orbitron and calls out azimuth and elevation; another student steers the antenna. A third student monitors the audio from a hand-held receiver and a fourth monitors the Dashboard and calls out the frame count. Other students watch the FUNCube site watching for Lauriston to appear. In this way, we can involve lots of girls, who so far range from Year 3 to Year 12. We are keen to contact other schools working the satellite to compare operating procedures.

    Reference the TLEs for Funcube-1, I was able to interpret the instructions for using Celestrak found elsewhere and put the following location into SDR Console’s list of satellite TLEs.
    http://www.celestrak.com/NORAD/elements/tle-new.txt
    Entry 2013-066B has to be selected for Funcube-1, and there are some options in SDR Console to rename this as Funcube-1. With this latest TLE I was getting perfectly straight doppler correction on the waterfall display. I know this isn’t strictly needed for Dashboard which does its own correction, but it all makes it look much nicer as seen in the 23/11 waterfall above.

  7. Any updates on the TLEs? I have been out all day and not able to look at the tracking. Yesterday’s TLEs were quite a bit out on the Doppler prediction.

      Nothing formal received yet.. nor have we had any better choices suggested Mike

    Strong signal on the beacon frequency. AOS and LOS were right on time on the 10:15 lcl pass but LOS occurred 3 minutes early on the 11:40 pass. Also heard the beacon very well last night. I guess I better dust off my TNC and attempt to copy the telemetry.

    Its been many years since I did any satellite work. I just discovered news of the FUNCUBE launch last weekend. So, I decided to set up a satellite station again. I copied this morning’s passes from Cheyenne, WY, USA using a simple full-wavelength loop antenna. Telemetry was strong, doppler was greater than expected, but it’s been a while since I did this. At this point, I’m feeling lucky to just heard the bird and see a few frames of data appear on the Dashboard. The N2YO predictions seem to be workingMany thanks to the team that makes this possible!
