D-SAT Mission update


This was another good week for D-Sat: the team is keeping its health in check through different LEOP (Launch and Early Operations Phase) tests and they will soon start testing the GPS and calibrating its sensors.
Also, they were recently able to determine D-Sat’s NORAD catalog number, which means that now Radio Hams as well will be able to acquire its signal.
Last but definitively not least, D-Sat sent us another souvenir from Space: a picture of clouds over the Atlantic Ocean and the coast of England.
Just look at this…

As of for this week’s issue, we thought it would be fun to explore the topic of mobile technologies. Happy reading!
Ciao, until next time!
