Delfi-C3 – DO64 Deorbiting Soon

After more than 15 years in orbit, Delfi-C3’s mission is about to come to an end. The team predict that re-entry will take place around November 16th 2023.

The re-entry date might vary depending on the solar activity, which is very hard to predict accurately. See also @Marco_Langbroek on Twitter for a similar prediction.

Delfi-C3 Re-entry Prediction

Delfi-C3 Re-entry Prediction

We would like to request all amateur radio operators / SWL’s / satellite enthusiasts worldwide to listen for Delfi-C3’s telemetry downlink on 145.867 MHz, 1200 baud AX.25 BPSK. We will hand out an award certificate to the person submitting the last Delfi-C3 telemetry frame.

This can be done either through the RASCAL software (updated version coming…), through the SATNOGS network or by sending us decoded telemetry frames with reception time and location via email to Delfi_at_tudelft.nl.

On behalf of the entire Delfi-C3 team, we would like to sincerely thank the worldwide amateur radio / SWL / satellite community for assisting the team by forwarding received telemetry and reception reports.

Back in 2008 we could not imagine the great support received so far and the many first we had, including a successful ground network and flying the first linear transponder in a CubeSat.

We strongly believe that Delfi-C3 has paved the way for many follow-on missions (both amateur and commercial), and has been a great step towards maturing CubeSat technology as well as training the next generation of space engineers. Stay tuned for updates!

On behalf of the team best 73s,

Delfi-C3 celebrates 6 years in space

Delfi-C3 (DO-64) has celebrated its 6th birthday on April 28, 2014. The spacecraft is still operational, telemetry only, on 145.870 MHz USB

Delfi-C3Delfi-C3 has exceeded its mission lifetime by six times now, and on-board telemetry still does not indicate degradation in performance.

So far, our distributed ground station network (DGSN) has collected 2037513 frames as of today, received by 376 registered radio amateurs and many more on the guest account, using the free RASCAL software. This would not have been possible without your continued support.

Thank you!

Please note that the original team of students has long graduated, and Delfi-c3 operations are done by very few volunteers. We continue to monitor the live telemetry in our spare time.

Delfi-C3 (DO-64) – 4 years in orbit

On April 28, 2012 the nanosatellite Delfi-C3 (DO-64) celebrated 4 years in orbit and is still alive and kicking!

This 3-unit CubeSat, developed by the Technical University of Delft in the Netherlands has been largely developed by students and performed technology demonstration experiments for the space industry in the Netherlands. After being launched on PSLV-C9 in 2008 it has been circling the earth for 1461 days (exceeding its design lifetime with 1371 days)!

The satellite still broadcasts its telemetry and measurement data which can be received using simple amateur radio equipment and using the RASCAL software (available on the Delfi website: http://www.delfispace.nl/index.php/participation/radio-amateur-participation).

The satellite project was also the birthplace of ISIS – Innovative Solutions In Space as the company’s founders and a significant number of its employees have worked on the satellite project at the start of their careers. We congratulate the university with the milestone and excellent demonstration that well coordinated student satellite projects can produce great results and exceed all expectations.

Regards,
Jeroen Rotteveel
