Cobham Flat Plate Antennas Enable Communication Between Iridium NEXT Satellites

Cobham announced that their products and services contributed to the recent successful orbital deployment of the Iridium NEXT satellites. Their antennas, motion control solutions, and RadHard microelectronics currently enable various Iridium NEXT systems. Iridium NEXT replaces and enhances Iridium's existing network of low-Earth orbit satellites.

Cobham motion control solutions on Iridium NEXT include flat plate antennas that are used for the inter-satellite links, providing communications between satellites of the Iridium NEXT constellation. They also include actuators for the solar array drive and solar array second axis.

The RadHard microelectronics contribution to Iridium NEXT includes power supply solutions, Field Programmable Gate Arrays (FPGA), LEON microprocessors and intellectual property, SpaceWire transceivers, 1553 transceivers, NOR flash and SDRAM memories, clock drivers, and MSI Logic. Additionally, four separate Application Specific Integrated Circuits (ASIC) perform control and data switching for various aspects of Iridium NEXT.
