Fun project! Did you look into NTN (Non-Terrestrial Networks) capable modules as an alternative to Iridium? I haven't played with NTN myself, but it seems modules such as SIM7070G-HP-S support LTE-M/NB-IoT as well as NTN networks, and could in theory serve the purpose of your Iridium tranceiver as well as your LTE module. This technology hasn't matured yet, and I suspect the roaming tarriffs are expensive, but I don't know how it compares to Iridium.
- lxgr 2y agoNTN seems to be only offered by geostationary satellite operators at this point, which unfortunately puts the use case from TFA out of coverage. See for example Inmarsat's coverage: https://www.inmarsat.com/content/dam/inmarsat/corporate/core-assets/coverage-maps/document/ELERA_BGAN_and_BGAN_M2M_coverage.pdf https://www.inmarsat.com/content/dam/inmarsat/corporate/core... I'm not even sure if Skylo is live with Inmarsat at this point, or if there are any other NTN providers covering oceans.
