Delfi Space

Nanosatellite development program of the Delft University of Technology

[Delfi Space @DelfiSpace]

We are very sad to announce that Delfi-PQ has re-entered in the atmosphere. On January 13th, it would have been 2 years in orbit but it gladly operated till the end!

[Delfi Space @DelfiSpace]

Delfi-PQ is also quickly coming to its final dive in the atmosphere. Its altitude has quickly decreased over the last couple of months and now only few days are left!

[Delfi Space @DelfiSpace]

It has been more than a week since Delfi-C3 reached the end of its life. She has been working really hard for the past 10 years.

Her radiant legacy will live on through the forthcoming TU Delft satellites(grandchildren). (Delfi-Next, Delfi-PQ)

Her last "beeps" were...

[Delfi Space @DelfiSpace]

@pe0sat Potentially yes, we cannot exclude that possibility. We still monitor it daily and we would love to receive another notification it operational.

[Delfi Space @DelfiSpace]

10 years today, happy birthday Delfi-N3xt!

@DelfiSpace Nice video https://t.co/9BIpRM9ukd #DelfiC3

[Delfi Space @DelfiSpace]

@Marco_Langbroek @SSperetta Loud and clear over Delft as well!

[Delfi Space @DelfiSpace]

Last reception so far, altitude dropping very rapidly...

[Paulo PV8DX @PV8DX]

@DelfiSpace DO-64 Close to reentry. 235km altitude - Pass North of Brasil 12nov2023

[Delfi Space @DelfiSpace]

@PV8DX Great! I just saw it pop-up in @SatNOGS

[Delfi Space @DelfiSpace]

Delfi-C3 over Brazil at 10:51 UTC today!

[Delfi Space @DelfiSpace]

Currently the last message received from Delfi-C3 @SatNOGS

Perigee 251 km at 6AM UTC today, still some time to go...

[Delfi Space @DelfiSpace]

@Marco_Langbroek @vk5qi @SSperetta Great to see Delfi-C3 is still going strong!

[Delfi Space @DelfiSpace]

355 frames received and submitted from Delfi-C3 in the past few days! Thanks @pe0sat @amsat_sm @Djoekster KD8CAO OK2FCO!

We are noticing TLEs might not be very accurate lately, the decay is getting extremely fast...

[Delfi Space @DelfiSpace]

Getting close to re-entry!

[Dr Marco Langbroek 🇬🇱 🇩🇰 @Marco_Langbroek]

Update of the #DelfiC3 reentry forecast.
While nominal forecasts are trending towards early Nov 13, arrival of a CME shockfront causing a mild geomagnetic storm is expected for 11/12 Nov, which might speed up decay. So either Nov 12 or 13 is possible

[Delfi Space @DelfiSpace]

@Djoekster @pe0sat @amsat_sm No need to set ip/ports. I only updated the basic functionality to submit frames so the server settings are not currently used.

[Delfi Space @DelfiSpace]

New Delfi-C3 demodulation / uplink client ready! Thank you very much @amsat_sm and @pe0sat for your help!

You can download the software here:
https://t.co/tPzGauU0kC

[Delfi Space @DelfiSpace]

The application can be started by just double-clicking on the jar file.

[Delfi Space @DelfiSpace]

The application requires Java 8 JRE at least and it can re-use the old connection credentials to submit to our repository. If you have never submitted telemetry before, please add your callsign in the settings window.
