Putting an Air Traffic Control Network Back Online

Early on Saturday morning, June 17, 2017, alarms started going off in the Globecomm Network Opera¬tions Center (NOC) in Hauppauge, New York, USA. Among its responsibilities, the NOC monitored and man¬aged a 43-site satellite network that carried radar and cockpit voice traffic for America’s air traffic control system. In most cases, these satellite links were backups to land-based circuits, but in some, satel¬lite was the primary link.airplane and clouds

Nothing the operators did had any effect. The satellite linking those sites – SES’s AMC-9 – had suffered a significant anomaly that took out its transponders and sent it slowly drifting out of its assigned orbital slot. The satellite network was a small part of a $1.7 billion contract awarded by the Federal Avia¬tion Administration to Harris to upgrade its communica¬tions, reduce their cost and improve their perfor¬mance. Globecomm was contracted to design and build the satellite portion, and then to manage it, as well as provide Tier One lifecycle support for the remote units and help desk support for the customer. That made them the resident experts on how to get the network up and running again. MORE <link to case study>
