[Avionics Today 12-08-2015] Aireon has signed a data services agreement with Air Traffic and Navigation Services (ATNS), South Africa’s Air Navigation Service Provider (ANSP). Through the agreement, ATNS will have 100 percent air traffic surveillance of the Johannesburg Flight Information Region (FIR) and the Cape Town FIR, which cover approximately 10 percent of the world’s airspace. This will be done through Aireon’s satellite-based Automatic Dependent Surveillance-Broadcast (ADS-B) service, scheduled to be operational in 2018.
ATNS has decided to implement space-based ADS-B to enable real-time visibility throughout their airspace. Increased visibility, coupled with real-time air traffic surveillance, improves both the safety and efficiency of air travel and gives air traffic control the ability to optimize airspace with more accurate, predicable data, according to Aireon.
“Much of Africa is currently without any air traffic surveillance. Aireon’s service will give us visibility into many regions, allowing us to facilitate seamless transitions between air traffic control providers. This will be achieved without any additional ground infrastructure and utilizing currently-mandated on-board avionics,” said Thabani Mthiyane, chief executive officer at ATNS.
ATNS signs their data services agreement on the heels of the International Telecommunication Union (ITU) adopting a resolution for primary spectrum allocation of the 1090 MHz frequency band for use by satellite-based ADS-B.
