Hi Scott,

Thanks for the congrats.
Actually D-SAT’s transmission can be triggered by telecommand or by a timer. During this initial mission phase we have communicated only over the Europe but if we know that there are people that are ready to listen to D-SAT in the US we can absolutely schedule some dedicated transmission over that area. For instance, we can schedule a SatAlert experiment transmission and some telemetry transmissions.

We just need to know when your visibility window starts 😊 !!

The involvement of radio amateurs in the U.S. could be much greater during the decommissioning phase because we are interested in collecting the telemetry data that will then be automatically transmitted during the re-entry trajectory. The final reentry maneuver, planned during the first week of August, will be activated the Italy, where D-SAT will start lowering its altitude, it will then pass over the North Pole to finally it reentry in the Pacific Ocean (closer to Hawaii). 

I hope this was helpful. Let me know if you need more information!

Congratulations on your project so far, Alessio.

I have a question, please...

Does D-SAT transmit over locations other than Europe?

I have seen great posts from others reporting reception of D-SAT, but over the U.S., I have not had any luck receiving the satellite.

If only SOME of the possible data is transmitted outside of Europe, it would be helpful if you would like to provide a list of what one might expect to receive.

Thanks very much!

Dear Sirs,

my name is Alessio Fanfani; I'm a young telecommunication engineer and an enthusiastic Italian satellite amateur (callsign IU5CRE).

Three years ago I started to work with D-Orbit, an Italian aerospace company, on an ambitious CubeSat mission called D-SAT.

D-Sat is a three-unit CubeSat designed, built, and operated by D-Orbit and it will be the first satellite in history that will come back into Earth's atmosphere in a safe and controlled way by means of a dedicated solid rocket motor and burn up instead of becoming new debris.

D-SAT was launched on June 23th, 2017 into a 500 km sun-synchronous orbit from Indian SHAR.

D-SAT is now fully operative in orbit and it is hosting three communication experiments in collaboration with an Italian university, high-level schools and a local hamradio community.

For more information on D-SAT, you can visit the mission's website (www.dsat.space), where you will also find a page entirely dedicated to radiohams (www.dsat.space/radiohams) where you can download the software necessary for the reception of D-Sat's signal.

We really hope you will consider joining us! Also, should you have any question about the mission, don't hesitate to ask!

Thank you for your time and consideration.
