One big differentiator is the nature of the antenna needed. The phased array antenna for starlink is apparently the size of a pizza box. Iridium satphones are comfortably handheld.
- bob1029 7y agoIs this a consequence of Iridium having L-band capabilities, or is it something else in the design?
- derekp7 7y agoIt has to due with the phased array antennas being used, which is basically a grid of antennas where each receives the signal at a different time (due to speed of light propagation). By delaying the processing of signals an appropriate amount from each antenna, all the individual signals can be combined to be the equivalent of pointing a dish antenna directly at a given satellite all the time as it is flying overhead.
