while in range of "cilization" send data every 10s over LTE when in remote location send data every 1h over Iridium save datapoints to the SD card show live position, speed, course and other parameters easy to extend further with exposed IO pins allow connection of extra sensors with I2C powered by 12V DC (car, ship, etc) backup power (~2hrs) case protecting from the elements However, to make debugging easier, I used a trick with hardware UART emulation, which allows a separate UART->USB converter to be connected to a single pin to monitor the device's operation. Further development of this device doesn't make much sense due to the exorbitant costs of Iridium transmission through RockBlock, namely £13 for a monthly line rental and £14 for the cheapest package of 100 credits, which equals 5 kB (!?).
