UKube-1 is scheduled to launch from Pad 31/6 at Baikonur on Tuesday afternoon. July 8th 2014 @ 15:58:28 UTC and to be deployed from the final stage of the Soyuz-2-1B/Fregat-M launch vehicle at 18:32:42 UTC.

The UKube-1 Operations Team has just issued this 1st edition of their Launch Briefing.

Launch Briefing ISSUE 1

And this is accompanied a worksheet showing the telemetry equations.

Briefing Workbook 20140702

Here are some prelaunch keps;

UKube-1
1 99999U 14999A 14189.66559000 .000005230 00000-0 05230-4 0 0019
2 99999 98.41000 240.000 0013100 54.7000 335.0000 14.76729233000011

UKube-1 carries a number of experiments and payloads and also the FUNcube-2 transponder and  telemetry sub-system. This is intended to support the current, very successful operations of FUNcube-1 and to provide an even better operational capability for schools and colleges to use for hands on educational outreach around the world. Further details of the educational outreach opportunities are available here https://funcube.org.uk/education-outreach/

When the FUNcube-2 sub-system is activated, the 1k2 BPSK telemetry will be downlinked on 145.915 MHz in the same way as already happens with FUNcube-1.

A new FUNcube-2 Dashboard UI will be released shortly. This will integrate directly with the existing FUNcube Central Data Warehouse and existing usernames and authorisation codes can be re-used.

When the transponder is activated, the downlink passband will be 145.930 to 145.950 MHz and the uplink passband  will be 435.080 to 435.060 MHz.

It is anticipated that the FUNcube sub-system may be tested for short periods during the next few weeks depending upon how the LEOP plan progresses.

AMSAT UK and their colleagues at AMSAT-NL are delighted that UKube-1 is carrying this FUNcube sub-system and wish every success to the UKube Operations Team and to all the many contributors to the project.

  1. Thanks Graham,

    I wasn’t quite sure how to convert the launch elements into keps and I had arrived at slightly different results and had received slightly different elements, so I converted yours to dummy TLEs – not real ones!

    ukube1
    1 12345U 00000 14189.77270833 .00000000 00000-0 10000-3 0 00013
    2 12345 098.4000 264.0000 0013000 054.7000 103.7000 14.81030000000019

    Unfortunately, those don’t seem to work quite right – do you have TLEs?

    The first pass here is 1939-1948, 20 minutes later than in the spreadsheet

    By the way, the table in the PDF quotes the Argument of latitude, I think it means longitude.
