ISS CubeSat Deployment NRCSD#28 (Voyager Space/Nanoracks) - ELaNa 52 - 2024-10-09 10:25 UTC

[fredy]

We have these deployments from ISS by Voyager Space Exploration Systems (Formerly Nanoracks):

Deployment 1, CySat-1 (3U): 6:25am ET (10:25 GMT)
Deployment 2, DORA (3U): 6:35am ET (10:35 GMT)

NRCSD28 CubeSat Deployments

Temporary NORAD ID	Satellite	Frequency	Notes	Deployed
AMATEUR UHF UHF
98798	CYSAT-1	436.375 MHz	IARU Coordinated	Via ISS Voyager Space(Nanoracks)
98911	DORA	436.825 MHz	IARU Coordinated	Via ISS Voyager Space(Nanoracks)

Satellites will be available for scheduling in Network around one hour before launch. To station owners, please have in mind that we follow ISS TLE for these satellites which means:

1. Don’t schedule too far away in the future as the TLE may change soon
2. Leave some timeslots for ISS observations, especially due to ISS SSTV event that will start later today.

TLE based on the latest ISS data.

I have cleared 2 good elevation slots, 10:48 - 10:56 and 12:25 - 12:34. Lets see them

[fredy]

We are ready for the deployment, for the first 24 hours we have 317 observations scheduled for DORA and 308 observations for CYSAT-1.

[PE0SAT]

CYSAT-1 deployed

DORA deployed

[EA4SG]

Over Madrid, Spain right now I have seen strong signals on DORA´s frequency but I copied nothing on CYSAT-1´s frequency

[PE0SAT]

Indeed no signals from CYSAT-1, lets keep our fingers crossed

[K4KDR]

Some DORA decodes over the U.S. as well, but nothing seen from CYSAT-1 so far.

[EA4SG]

One DORA satellite frame decoded some minutes ago, orbit number 2 over Madrid, Spain…

[dl7ndr]

DORA: Decoded and uploaded 20 beacons from 12:2x and 14:0x UTC passes.
CYSAT-1: not heard

[dl7ndr]

DORA:
On github they write 7.3 kbps, on IARU it’s 7.4 kbaud.
And on top, UZ7HO’s modem says 7416 bd.

[PE0SAT]

There GNURadio flow graph has the bit rate value as: 7415.77

[K4KDR]

Had my best SDR & antenna looking for CYSAT-1 during each of the ISS passes today, but nothing seen. Hopefully this will be one that starts transmitting later, despite zero here right after deployment.

[PE0SAT]

Space-Track has shares some TBA objects and one is matching DORA

Hi Jan,
Please share link to where this GRC is. TKS

[PE0SAT]

Hi Bob,

As mentioned in my Twitter message, it can be found at this location

Also have a look at the readme file.

Let me know if you have some questions.

Jan

[PE0SAT]

There where only two new objects, so CYSAT-1 will be 61501

[N6RFM]

Thanks Jan!

[fredy]

Satellites in DB and Network now follow these two objects!

Hi All,

I’m the project manager for CySat. We think our antenna has not deployed due to a logic error in our code. We are attempting to send a deployment command to the satellite via ESTTC, but are requesting help if possible, since we somewhat limited access and are still setting up automated antenna control.

Our ground station github is located at GitHub - M2I-CySat/CloneComm: The new CySat-1 Ground Station for use with satellite-ground communications. The yaml is in there, as well as the GNU Radio set up we’ve been using (called “sat-Downlink-Uplink-Fall2024”). We believe the ESTTC command we need to send is “ES+W22F2110A”, which should force an immediate attempt to deploy the antenna.

Lastly, I wanted to say thank you from all of us here, because we’ve been watching all the reports and it helps us feel a little bit less crazy.

John
