Happy St. Patrick's Day to our colleagues, friends and followers from Ireland! 🇮🇪 🍀

To celebrate, find out how a team of Irish university students have built Ireland's first satellite, EIRSAT-1, as part of our Fly Your Satellite! programme.

If you haven't already heard about EIRSAT-1, Ireland's first satellite, then check out https://t.co/joj3j7tidh or more info.
This is really exciting and is a great for the Amateur Radio community in Ireland to get involved in 😎
You can also follow EIRSAT-1 on Twitter.

@pe0sat @JA0CAW @EIRSAT1 Of course! Fresh from the flight model. S/C currently in test with convolutional encoding but we can get some more recordings without it soon. Full recording and trimmed version for smaller file size available here: https://t.co/3mPKKliHCY

UZ7HO is also working on a Sound Modem version that supports EIRSAT-1.

[David Murphy @jaaaaam]

Our paper describing the design, assembly and validation of the @EIRSAT1 GMOD gamma-ray payload is now available online. https://t.co/MCbcJrfj3W It represents a huge amount of work from lots of talented people @UCD_Cspace with support from @esa, @scienceirel, @IrishResearch.

The @EIRSAT1 team, participating in the second round of @esa’s Fly Your Satellite! Programme, has successfully concluded the environmental test campaign on their Engineering Qualification Model - a major milestone! Congratulations 👏 https://t.co/KRDutIsM7b

[EIRSAT-1 @EIRSAT1]

Check out this video of the installation of the EIRSAT-1 Engineering Qualification Model in the ESA Education CubeSat Support Facility thermal vacuum chamber this week!

Check out this tweet thread on the LEDSAT mission, launching in T-16 hours or so 🚀

[EIRSAT-1 @EIRSAT1]

We have two exciting opportunities to share!

- MSc (Research) in EIRSAT-1 and Nanosatellite System Modelling at @UCD_physics. More details here https://t.co/fu8ilOzfxi

- PhD in Nanosatellite System Modelling and Testing at
@UCDEngArch. More details here https://t.co/vFO9xumUXO

At 37.4km high, GMoDem holds the altitude record for anything I've worked on, but we're hoping to smash that record soon!

[David Murphy @jaaaaam]

Our paper on the high-altitude balloon flight of GMoDem is available here: https://t.co/47SZzHUiG5 GMoDem was our prototype version of the @EIRSAT1 GMOD gamma-ray detector.

[David Murphy @jaaaaam]

We're really grateful to everyone that helped make this happen, including the ASCOT team from @UofNH who let us fly piggy-back on their gondola and the folks @NASA Columbia Scientific Balloon Facility. The detector is the product of long-standing support from @esascience.
