UKube-1 Update

by

UKube-1 was successfully launched, as planned, on Tuesday 8th July 2014.

Signals were heard from the spacecraft during the first pass over the UK from both the main telemetry transmitter on 145.840MHz and the FUNcube 2 transmitter on 145.915MHz.

Presently, commissioning of the spacecraft is continuing, and there may be future occasions when the FUNcube  telemetry transmitter will be activated during this period.

Although we have not yet released a FUNcube 2 version of the Dashboard, the existing version 820 will correctly decode the data and forward it to the FUNcube Data Warehouse. If you do receive some data frames please forward them to the Warehouse in the usual way.

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.

Here are some prelaunch keps;

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 http://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 personnel will be supporting the UKube-1 operations team at Chilbolton during the immediate post launch period and will be ensuring that regular status reports are made available via IRC and other channels.

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.

 

 

 

 

 

 

 

 

 

 

 

 

 

One millionth packet milestone!

by
FUNcube Dashboard

The FUNcube Dashboard

 Many stations have been receiving the telemetry transmitted by FUNcube-1, which has now been in orbit for 221 days. The spacecraft, which has been operating nominally since launch, is providing on-board health and science data for the many schools and colleges who are already participating in the project around the world.

Since launch, data has been received by more than 650 stations around the world and today our online Data Warehouse received its one millionth packet of information. The Warehouse is now storing more than 256MB of telemetry which is available for educational and research use.

We have been successful in capturing almost 25% of all the telemetry transmitted including almost all of the Whole Orbit Data. This success is a great tribute to our designers of the Flight software, the Dashboard programme and the matching Data Warehouse.

We are also immensely grateful to all the schools, colleges, radio amateurs and other listeners who are providing this data and want to encourage everyone to continue to listen to FUNcube-1 and to upload the data to the Warehouse. This will help enable the project to continue to provide a complete and current data set for analysis.

Count of data uploads since launch.

Count of data uploads since launch.

We would, of course, also love to have additional receiving stations in the FUNcube Ground Station Network. This applies especially to anyone near the poles or who is located on an island in the middle of ocean. Their involvement would help us improve our rate of data capture still further.

Our records show that there were three stations who actually managed to upload the same one millionth packet to the Warehouse today. They are G0EID, OM3BC and DL3SER. If they could contact “operations at funcube.org.uk” we will arrange them to send them a small prize to honour their contribution to the project.

FUNcube-3 Payload successfully launched

by

At 19.11 UTC  19th June 2014, the DNEPR launch vehicle left the pad at Yasny and successfully delivered more than 30 objects into the expected orbit about 600km above the surface of the earth.

Amongst those objects were the two QB50 precursor spacecraft and good signals were heard from both in less than ten minutes from their deployment by ZS2BK, ZS5SB and ZS1HD in South Africa.

Both of these spacecraft carry amateur radio payloads:

QB50p1 has a 145.815 MHz BPSK telemetry downlink and carries the FUNcube-3 400 mW inverting linear 435/145 MHz transponder provided by AMSAT-NL with support from AMSAT-UK.
- 435.035-435.065 MHz Uplink LSB
- 145.935-145.965 MHz Downlink USB

QB50p2 has a 145.880 MHz BPSK telemetry downlink and carries a 435/145 MHz FM transponder and FX25 data transmitter from AMSAT-F.
• 145.840 MHz 9600 bps FSK FX25

It is expected that the AMSAT payloads will be activated after a few months of operation of the science payloads.

Our thanks go to the stations in South Africa who received the first signals and also to the ISIS teams both at the launch site and at their HQ in Delft. A job very well done!

FUNcube-3 payload launch information

by

We anticipate that the DNEPR launch of this payload on the QB50p1 CubeSat will take place as previously stated. This Thursday is the day!

To be precise, lift off is expected to take place from Yasny on 19/06/2014 @ 19:11:11 UTC and the deployment of the various payloads will take place over the Indian Ocean in a similar fashion to the launch of FUNcube-1 last November. Pre-launch TLEs have not yet been made available but the details of the initial 145MHz CW  transmission format for both QB50p1, and its near twin QB50p2, can now be seen here: http://www.isispace.nl/HAM/qb50p.html QB50p1 carries a linear UV transponder provided by AMSAT-NL, with support from AMSAT-UK, which I s similar to that on FUNcube-1. QB50p2 carries an UV FM transponder and FX25 data transmitter from AMSAT-F. It is expected that these payloads will be activated after the science missions have been completed. AMSAT-UK will be monitoring the launch event and watching for signal reports on the IRC #cubesat channel throughout the evening.

Future FUNcube missions – 2014 launch dates – FURTHER UPDATE

by
 

 The latest news we have is:

We have received confirmation that UKube-1, which is hosting the FUNcube-2 payload, is now scheduled for a Soyuz launch on Saturday June 28th with the following day as a back-up.  The launch time has been quoted as 15:58:28 UT with separation some 9253 seconds later.  We still understand that, immediately after deployment and activation, UKube-1 will commence transmitting a CW beacon and that this will be later followed by an AX25, 1k2 BPSK beacon. Both beacons will be on 145.840MHz. The FUNcube-2 payload, with its telemetry downlink for educational outreach, is expected to be tested later.

FUNcube-3 is the transponder only payload on the QB50 precursor CubeSat “QB50P1″. This mission is now scheduled to launch on June 19th on a Dnepr LV from Yasny. The launch time has been quoted as19:11:11 UTC but this has not yet been confirmed.  The initial beacon signals, from the main transceiver, are also expected to be AX25, 1k2 BPSK packets on 145.815MHz.

Again more information will be provided as soon as it becomes available!

We have received confirmation that UKube-1, which is hosting the FUNcube-2 payload, remains scheduled for a Soyuz launch on June 19th. We do not, as yet, have any lift-off times or TLE’s for this launch but we will make these available as soon as possible. We believe that, immediately after deployment and activation, UKube-1 will commence transmitting a CW beacon and that this will be later followed by an AX25, 1k2 BPSK beacon. Both beacons will be on 145.840MHz. The FUNcube-2 payload, with its telemetry downlink for educational outreach, is expected to be tested later.

FUNcube-3 is the transponder only payload on the QB50 precursor CubeSat “QB50P1″. This mission is currently scheduled to launch “Not earlier than the second half of June” , on a Dnepr LV from Yasny. The initial beacon signals, from the main transceiver, are also expected to be AX25, 1k2 BPSK packets on 145.815MHz. Again more information will be provided as soon as it becomes available.
