Thales said it completed phase four of the Mexico’s nationwide air traffic modernization program for the country’s Air Navigation Service Provider (SENEAM1). The fourth phase of the program, which Thales began in 2004, involved the upgrade of sites at Mexico’s Mazatlan, Hermosillo, Puerto Vallarta, San Jose and Tijuana airports. Mexican Air Traffic Control Centers are now operating with the Thales EUROCAT ATM system, which is a modular automation system that controls aircraft through the departure, en-route and approach phases, the company said. Thales has upgraded 16 Air Traffic Control Units and will throughout the life of the contract provide training for SENEAM, which includes air traffic controller training courses and technical training courses.
