LEO Communications Networks

Iridium NEXT

Under a contract with Thales Alenia Space, Northrop Grumman conducted integration and test services for Iridium NEXT, the next-generation satellite constellation of Iridium Communications Inc. Northrop Grumman integrated the communications payloads and platforms for 81 low-Earth orbit Iridium NEXT satellites and tested the systems at its satellite manufacturing facility in Gilbert, Arizona.


Northrop Grumman is a pioneer in low-Earth Orbit communications satellites, with its heritage company having conceived, built and deployed the ORBCOMM network. ORBCOMM was the first global communications network to employ a constellation of LEO satellites. From 1994 -1999 the company built and deployed 35 satellites, integrated five "gateway" ground stations and a network operations center to manage the satellites and process their data.

The narrow-band ORBCOMM network is utilized to send and receive short messages to mobile assets such as trucks, trailers, marine vessels, railcars and other remote assets that are often out of reach of terrestrial communications networks. In 2007, six communications subsystems were delivered to ORBCOMM, Inc. for satellites which were launched in 2008 to augment the ORBCOMM in-orbit fleet.
