Soyuz-2.1a / Fregat Baikonur launch 2021-03-22T06:07 UTC

Do you also use ikhnos against the analyst 88XXX objects?

To be honest, I avoid to use these OBJECTS as are not officially(from spacetrack) from this launch.

Is there any change from this status?

One of the unknown satellites at 435.800 MHz is BCCSAT-1 as the signal contains its callsign, from observation SatNOGS Network - Observation 3858224 checking the two signals that are visible in the audio waveform we have:
HS0W_1

EDIT: Here are two other signals around 435.800 MHz:

One at ~435.805 MHz which is just a carrier:
https://network.satnogs.org/observations/3861511/

One at ~435.795 MHz which looks like dots:
https://network.satnogs.org/observations/3861451/

Wondering if any of these two belongs to STECCO transmitter or maybe to BCCSAT-1 too.

For completeness, we need to have in mind that we still missing reception of FEES and the two CANYVAL-C satellites.

EDIT2:

Signal at 435.795 MHz could be also BCCSAT-1, as in this observation SatNOGS Network - Observation 3861494 it is visible at this frequency.

FEES LoRa beacon are recieved on tinyGS network.
Observation follow OBJECT R(47947). Maybe next candidate is OBJECT J(47940).

Good to hear that FEES is alive, very sad that they use proprietary protocol on amateur radio frequencies and violate Radio Amateur Service.

Results for UNISAT-7, SMOG-1 and ORBICRAFT-ZORKIY are also confirmed by strf observations of @PE0SAT.

@fredy
The OBJECT J(47940) assigned to DMSAT-1 by Celestrak.

@George-KC I’ve seen that several OBJECTS are identified in spacetrack but with a quick search I didn’t find any public evidence that support that identification.

Unfortunately In the past we have seen several cases of mis-identification, so we trust only statements that can be supported by public data. If there are any for the DMSAT-1, please let us know.

EDIT: One more thing is that we don’t have TLE sets for every payload of this launch which makes the identification more questionable.

While not centered exactly on 435.800, and certainly not 9k6 FSK, for the first time in many days there were a series of sad-sounding tones with doppler consistent with Object “M” on the 1443 UTC pass over the U.S. East Coast while searching for any sign of STECCO. It may be helpful if anyone could confirm a repeat of this track to give some idea whether STECCO is still functioning or not (or to attribute these tones to some other object)

@K4KDR the OBJECT M is what you followed and saw the signal or you used some other method to fit it on the signal?

We have some similar observations in SatNOGS and @PE0SAT has an observation with strf that fits OBJECT AG:

PS This object doesn’t look to be the same with the BCCSAT-1 that was spotted around that frequency Soyuz-2.1a / Fregat Baikonur launch 2021-03-22T06:07 UTC - #68 by fredy

PS2 Given that we don’t expect any other satellite on this frequency from this deployment and that no other satellite interferes on that frequency on all these observations, I’m going to set STECCO to follow OBJECT AG. But if @K4KDR confirm that the signal is indeed OBJECT M in his case, then probably we are talking about one more satellite.

Hi Scott,

Thanks for supporting the search, I will schedule some extra high strf passes the coming days and see if we can determine with more accuracy some matching TLE.

All the best

We found something tonight.

  • Object 47940 (Which I used to receive BCCSAT-1) sometime very close to RS-44 satellite.
  • Both object share footprint most of the time
  • The downlink frequency of both object are very close

BCCSAT-1 DL 435.635 MHz

RS-44 (5 Watt RF PW)
Transmitter power: 5 watts
Beacon: 435.605 MHz – transmits CW call sign RS44

Inverting transponder:
Earth-to-Space: 145.965 MHz +/- 30 kHz
Space-to-Earth: 435.640 MHz +/- 30 kHz

I observed human voice durinng reciving BCCSAT-1 telemetry which I suspect that is RS-44 transponder downlink signal.

That could be a Doka FSK channel from RS-44 being active.

‘AG’ would make good sense; it’s about the right distance behind ‘M’ to line up with my observations. I will start tracking ‘AG’ when monitoring for STECCO. Thank you!

There are new TLE sets from spacetrack, a quick update was for BCCSAT-1 that is now changed to follow OBJECT AK(48082) as @PE0SAT suggested after fitting some strf observations. More updates to come later today.

Most of the results are also confirmed by strf observations of @PE0SAT.

Another confirmation that the carrier like signal we see for STECCO is STECCO is that the OBJECT AG orbit is close to the satellites that were deployed from UNISAT-7. So, personally I’m 90% sure that this is STECCO. Also from https://network.satnogs.org/observations/3884671/ is clearly visible that is not related with the BCCSAT-1 which transmits outside its ITU coordination.

First I want to thank you for all the observations of the DIY-1 that are made daily by satgnos.
I thought that in USB mode it would be easier to decode the telemetry that is recorded daily but clearly it is undecodable. The correct mode is CW. Please, the the next observations pass to CW, so that we can decode them correctly the audio.

Again thank you very much!
