Macedonia's air navigation service provider, M-NAV, has put out a call to find a consultant to assist with the upgrade of the country's air navigation system. The consultant will be required to help organise the procurement process for the project, assist with the preparation of tender documentation and take part in the evaluation of the bids. Interested companies are invited to apply by March 24. The project, which is valued at thirteen million euros, will include the installation of a mew Air Traffic Management (ATM) system, the upgrade of several communication facilities, the installation and testing of a new VHF radio system, new voice communications system and a new digital system for recording voice channels (Voice Logging System). Furthermore, a new surveillance radar will be installed and meteorological equipment at Skopje and Ohrid airports will be improved. Preparations for the project initially began in 2014. The upgrades are expected to be completed by 2019.
