What frequency band is used for terrestrial gateways in the Iridium Satellite Systems?

The frequency band used for terrestrial gateways in the Iridium Satellite System is 29.1 - 29.3 GHz, which is designated for up-link communication. This band supports the transmission of signals from ground stations to the satellites in the Iridium network.

The significance of this frequency range lies in its appropriateness for satellite communication, which typically requires higher frequencies for effective transmission and reduced interference. By operating in the K-band, which encompasses this range, Iridium ensures enhanced bandwidth for data communication, allowing for a larger volume of traffic and more efficient service delivery.

Additionally, utilizing this band allows for line-of-sight communication between terrestrial gateways and satellites, vital in minimizing signal loss and maintaining high-quality connections. In the context of satellite communications, up-link frequencies are specifically utilized to send data from ground stations to the satellites, making this frequency range essential for the operational integrity of the Iridium system.
