Cutting the data rate probably has implications on the transmit side, i imagine that may complicate things. Given it’s possible to make a long battery life short-burst-data iridium device, it certainly seems in the realm of possibility, but no phased array or high bandwidth there. The dish takes about 20-30min on first boot, that may have included a software update. If it’s not moved, reboots seem fairly quick, software update took it down for under 5min. The OS boot is probably not the slow part - I assume a lot of RF magic to find and track the sats.
