The scheduled launch would bring the total number of Iridium NEXT satellites in space to 30 as part of a potential $3 billionÂ program to replace an existing constellation with 75 new communications satellites by mid-2018, IridiumÂ said Friday.
Iridium also set Oct. 1 as a backup launch date for this batch of 10 satellites that will work to deliver service in orbital plane four.
SpaceX also plans to carry out the fourth satellite launch in late November.
The new satellite constellation will feature Aireonâ€™s automatic dependent surveillance-broadcastÂ platform designed to provide aircraft surveillance and tracking service as well as theÂ Iridium Certus communications platform.
Thales Alenia Space manufactures Iridium NEXT satellites, whileÂ its subcontractor Orbital ATKÂ performs assembly work on the satellites through its Gilbert, Arizona-based facility.
