Network Reference - Satellite

Each Iridium satellite is ~4 meters high and weighs ~667 kg fully fueled. It comprises of three L-band antenna panels providing the 48 beams of footprint. The satellite has four 23 GHz cross-links antennas. These antennas point to the nearest spacecraft in the same plane (fore and aft) and in the two adjacent co-rotating planes. The "feeder link" antennas relay information to the terrestrial gateways. The spacecraft payload is the dominant component with high-speed digital switching to handle complex telephony routing.
