Era Corp., Reston, Va., said it will provide multilateration (MSS), automatic dependent surveillance-broadcast (ADS-B) and Squid vehicle tracking services at the O.R. Tambo International Airport (formerly Johannesburg International Airport) in South Africa. Era already has a pilot surveillance system installed at Cape Town International Airport for wide area and surface surveillance. The newly expanded system will have coverage extending to roughly 225 nautical miles from the airport. O.R. Tambo International Airport, Africa’s busiest, has begun renovations in order to support growing passenger demand and the projected increase in operations.
