Observation 11554171: NanoFF A (58810)

Regarding Observation 11554171

Little question.
I just gave it a try to gr_satellites on wsl on windows. finally seems to work… (or at least I think so…)
Now considering that the SNR is quite poor of this observation (yes… I’m trying to improve it!)
I just run the ogg to gr_satellite and I got these “data”…

What is actually going on?
Are these data or a bunch of errors from the decoder?

📡 Running gr_satellites with satellite 'NANOFF-A'...
log :warning: `pdu_to_tagged_stream` has moved to gr-pdu and will be removed from gr-blocks soon. Please update to use pdu.pdu_to_tagged_stream()

[3/3] ✅ Done. Output saved to: nanoff-a.kiss

NanoFF A and B’s beacons include their callsigns from the 11th byte on.

For NanoFF B (DP0NFB) it would look like this:

00 B6 04 00 00 00 00 00 28 0E 44 50 30 4E 46 42 00 01 …

You also “decoded” 9k6 (transmitter . 9k6 FSK downlink).
That’s pretty unusual. The Mobitex protocol is normally transmitted in 4k8.

So I probably got something wrong right?
I’m astonished by the amount of data decoded if I have to be honest

Maybe one of the other satellites from this University that is also active on 435.950, TU Berlin always uses the same frequency.

Ah Right!

yes this is definitely the twins FFA and FFB
the A has baud of 4800, the B has 9600

They launched together and they probably still are on the same orbit.
NanoFF A, B (Tubsat 28, 29) - Gunter’s Space Page

I guess there is no tlm decoder.

TU Berlin has a link with details on there satellites.

Both transmitting at 4k8. Never saw 9k6.

They are very close to each other.
You’ll never know in advance which one will beacon on next orbit.
Sometimes both transmits alternating.

To upload each beacon to the correct Norad ID you may use the gr-satellites Uploader.

iirc I had to hunt for it, but got both rates from both NanoFF-A and NanoFF-B

You are seeing these frames now because gr-satellites main branch comes with the new Mobitex-NX deframer I implemented (#723). Happy to see it beeing used!

As explained by others, since NanoFF A & B both use the same modulation & framing, they can only be differentiated when the deframer is provided with the callsign, which is not the case for the NanoFFs yet (see NANOFF-A.yml vs TUBIN.yml).

Once a callsign is provided in the satyml, the Mobitex-NX deframer will compare the received callsign against this reference and reject frames with more than the specified number of bit errors (default specified by DEFAULT_CALLSIGN_THRESHOLD_RELAXED = 12 in mobitex_deframer.py#L34). The current default threshold didn’t consider that there might be two satellites with a similar callsign in the same recording. Receiving NanoFF-B while NanoFF-A is selected will cause (without any additional bit errors due, eg. due to low SNR) will be seen as 8 callsign bit errors. Thus the default threshold should probably be set lower than that.

Calculation of expected number of bit errors

CRC is crc16_ccitt_zero.

  • NanoFF-A: callsign=b'DP0NFA', callsign_crc=b'\xacI'
  • NanoFF-B: callsign=b'DP0NFB', callsign_crc=b'\x9c*'

→ difference seen by compare_expected_callsign: 8 bits


@ea4gpz, @dl7ndr: With the current architecture of gr-satellites, there is always only a single satellite satellite selected to be decoded (even though in cases such as NanoFF, frames from multiple different satellites might be received accidentially). Maybe we can start a discussion upstream in gr-satellites towards supporting the output of telemetry frames tagged with the information on which satellite was received? Then the telemetry forwarder doesn’t inspect the frames itself, but can rely on gr-satellites itself to provide this information, which at least in the case of NanoFF-A/B it already has (or rather will have, once the callsign is provided with the satyaml with #745). What are your thoughts on this?

Hi Fabian,

That’s the corresponding issue for GetKISS+.
You select one satellite and hope that only this satellite will be received (and its data uploaded).

To be more flexible, I’ve built an uploader in gnuradio with blocks from gr-satellites which looks for callsigns and decides upon them to which Norad ID the data has to be uploaded.
One could use it while disabling the upload function of gr-satellites.

Let us hear (the other) Daniel if there is a way and if it makes sense to put this external uploader directly into gr-satellites.

Several things in gr-satellites were built under the assumption that at any given time there is only one satellite on a given frequency in view from a particular groundstation. This is being broken in multiple cases recently, since some groups are launching multiple satellites in the same launch that all use the same frequency. Generally speaking, there is a lack of a suitable spacecraft ID field that can be used to univocally identify each satellite. In these Mobitex-NX satellites there is a callsign field that can be used. AX.25 has a source address, but many times it is set to a nonsensical value instead of a real and unique amateur radio callsign. Other modems such as the AX100 generally lack any kind of spacecraft ID field.

This said, any deframer in gr-satellites that can identify the spacecraft in a reasonably way using a callsign or address field could add metadata to the PDUs containing the satellite identification. The telemetry submit block requires a NORAD ID (for most server types) and assumes that data from a single satellite is presented at its input. If its input frames contained a satellite identifier, it could ingest data from multiple satellites. An open question is how to map satellite identifiers to NORAD IDs. Maybe this should be the responsibility of the deframer, since the formatting of callsign fields is modem-dependent. In any case, for good management this would need configuration files that map spacecraft IDs to NORAD IDs.

Currently, my gr-satellites uploader maps those IDs after and fed by the (e. g. gr-satellites) deframer using a separate ini file.

I’ve asked the operator: 9k6 has not implemented.

I dug out the recordings and looked at them with inspectrum, and indeed looks like there’s only 4k8.

How do you know what part to select and the what number of symbols ?

number of symbols is just the length of the ruler here, to see if the transitions line up or not. using the scrollbar to move between the different packets in the iq-dump.
also visible in the preamble tones being the same distance on all of the packets.
