I'm a researcher and I'm looking to build a very tiny embedded system. I must to send data from the desert and above the ocean, to do that I think that my single option is to use satellite transmission (and not GSM).
Thus, I found Iridium Satellite (RockBLOCK) but my main issue is that their Arduino module is too big for my project (4cm of length and too heavy).
Do you know if there is other module to send data via satellite with Arduino ? If not, do you know other microcontroller which can do that ? (Using Arduino is not mandatory for me)
Thank you a lot, Sincerely.
