Firefly CubeSat Mission to Study Lightning

Firefly_CubeSatFirefly carries a Very Low Frequency (VLF) receiver covering from a few ten’s of Hz to to tens of kHz to measure the radio waves emitted by lightning. It was launched November 20 on a Minotaur-1 rocket and NASA have released a video about the satellite.

The YouTube description reads:

Somewhere on Earth, there’s always a lightning flash. The globe experiences lightning some 50 times a second, yet the details of what initiates this common occurrence and what effects it has on the atmosphere – lightning may be linked to incredibly powerful and energetic bursts called terrestrial gamma ray flashes, or TGFs — remains a mystery. In mid-November, a football-sized mission called Firefly, which is funded by the National Science Foundation, will launch into space to study lightning and these gamma ray flashes from above.

The NSF CubeSat program represents a low cost access to space approach to performing high-quality, highly targeted science on a smaller budget than is typical of more comprehensive satellite projects, which have price tags starting at $100 million. The CubeSat Firefly, by focusing its science goals, will carry out its mission in a much smaller package and at a considerably lower cost.

The Firefly mission also emphasizes student involvement as part of the ongoing effort to train the next generation of scientists and engineers. Students at Siena College, in Loudonville, N.Y., and the University of Maryland Eastern Shore, in Princess Anne, Md., were involved in all phases of the Firefly mission.

Delfi-n3Xt 2400 bps BPSK decoded in Japan

Delfi-n3Xt Satellite

Decoding the Delfi-n3Xt 2400 bps BPSK beacon on 145.870 MHz has proved to be very challenging but Tetsurou Satou JA0CAW in Japan has succeeded in decoding some frames.

He decoded three frames of telemetry in two passes on November 27.

In a recent update Jasper PC4JB from the Delfi-n3Xt team said:

We have noticed however that the DUDe telemetry client does not properly indicate the frequency offset and it is very difficult to get a lock on the signal.

Also our ICOM910 receivers have too limited bandwidth to receive a 2400 bit/s BPSK signal properly (although we had a few packets decoded with this, so it is just on the edge of what is possible). We now use only AR5000 in combination with an SDR to record a wide spectrum in IQ files. This way we can replay the files and retune the signal again and have been able to decode more packets than before. This morning at our second pass we were lucky to have a real time lock on the signal and retrieve many packets, so it is possible to have it right at once. But of course we would like to get the ‘luck-factor’ out of it.

A few people will look into the Costas PLL inside DUDe to see if we can improve its performance.  Meanwhile, you can regard Delfi-n3Xt as a real challenging game to decode packets…

FUNcube-1 (AO-73) Update November 26

The FUNcube Team have some new TLEs for object 2013-066B

2013-066B
1 39417U 13066B   13330.15401895  .00003238  00000-0  45063-3 0   205

These still seem to be the best fit but the team would appreciate any comments.

There is some discrepancy between the original published frequencies for the spacecraft and those we all experiencing in flight.

It is possible that the transponder input bandpass frequencies may also be varying due with the colder than expected temperatures being experienced.

You can track the RF board temp on the telemetry.The RX board temp varies by some 30 degrees C over a full orbit and this will be affecting the oscillator frequencies.

The team do not yet have final confirmation of the object number so the Doppler shift is probably not yet being precisely counteracted by the various Tracking Apps which will be adding to the confusion.

So just at the moment we cannot give precise guidance on the uplink/downlink formula that users should employ but the team are working on it and would appreciate input and observations.

Analysis of the housekeeping data suggests that all is well on-board FUNcube-1, the team are considering switching to continuous transponder mode for a few hours over the weekend to determine the effect that this would have to the on-board temperatures. Presently we are looking at trying this during an early morning pass over the UK on Sunday, December 1 but this will confirmed nearer the time.

FUNcube-1 has had some good media coverage from the BBC in the past few days:

CAPE-2 Text-to-Speech heard in Japan

CAPE-2 CubeSat - University of Louisiana

CAPE-2 CubeSat – University of Louisiana

The Cajun Advanced Picosat Experiment satellite CAPE-2, built by students at the University of Louisiana at Lafayette, launched on a Monotaur-1 on November 20, 2013 at 0115 UT.

On November 24 Tetsurou Satou JA0CAW in Japan made this recording of CAPE-2′s Text to Speech functionality in action. The signal is weak, but it is saying: ”Hello I am the Satellite Project from the University of Louisiana at Lafayette” twice in the recording.

The CAPE-2  frequencies are 145.825 MHz FM and 437.325 MHz FSK. On the VHF FM frequency the beacon will be in CW and AX.25.

Update December 2, 2013:

Here is a link to all information the CAPE Team currently has for tracking the Satellite. A program will be released in the next few days to decode data.

http://ulcape.org/cape-2-tracking-update-12022013/

On behalf of the CAPE-2 Team, we would really appreciate any data you can relay to us on the satellite.

Sincerely,
