SRA International subsidiary Era Systems achieved site acceptance with the ATNS, South Africa’s air navigation service provider (ANSP), for its terminal area automatic dependent surveillance-broadcast (ADS-B) and multilateration surveillance system at the Cape Town International Airport. The system by Era, which was acquired by SRA in July, provides wide area surveillance in the Cape Town terminal area out to 60 nautical miles from the airport. Data from the system will be fed to the ATNS EUROCAT system and fused with primary and secondary surveillance radar information to provide air traffic controllers complete situational awareness. The system will be used operationally once certification from the South African aviation authorities has been obtained, the company said.
