One of the many Cubesats launched on the recent SSO-A mission was the Italian 3U Cubesat EAGLET-1. This satellite transmits telemetry on 435.200 MHz and it is to relay AIS signals emitted by ships from one of two VHF frequencies to 435.800 MHz. As far as I can see these frequencies have not been coordinated by the IARU. The operations of this satellite have nothing to do with amateur radio. It is a commercial satellite, so an experimental license also does not apply. For details see: https://digitalcommons.usu.edu/cgi/viewcontent.cgi?article=3378&context=...
After this satellite a constellation of 20 similar satellites is planned. Can/should we do something about this?

Looking further into this strange satellite that is active in the HAMRADIO spectrum without following the IARU regulation (http://www.iaru.org/satellite.html), I also found this: https://www.ohb.de/en/news/ohb-italia-nanosat-eaglet-1-successfully-launched...

Can we do something?, I am not sure, but one thing we should do, and that is contacting the organizations and remind them that there are regulations they should adhere to.

Presumably the Italian government licensed this commercial operation on the amateur bands, which is unfortunate.

It would be reasonable to cite interference to a licensed station in the amateur-satellite service (must be documented) as a reason for asking your administration (FCC in the USA) to report the problem to the licensing administration under RR Article 22 and demand that the offending transmissions cease.
Have fun!!

To thrive in life, you need three bones: a wish bone, a back bone, and a funny bone. - Reba McEntire
The EAGLET-1 paper referenced below was presented in August 2016 (over TWO years ago) at the 30th AIAA/USU Conference on Small Satellites, and now, two years after the paper was given and the satellite is launched, folks are upset with the satellite operating in OUR 70 CM band. Folks, we knew about it at least two years ago. If you read the paper, they plan on a constellation of 20 of these satellites, presumably in the same "uncoordinated" band.
Art Feller is correct in that we have a protocol in place to bring this to the attention of our FCC and the IARU and to the developing satellite organization(s). What we need is an AMSAT sponsored and supported "watch-dog" group who will monitor upcoming proposed satellites and initiate the required noticing to the FCC and the IARU of violating satellite transmission plans.
You don't wait until the satellite is launched and then complain.
