North American vendor whose REVAL digital tower came from Estonia's Cybernetica in a February 2022 acquisition.
Adacel sells the REVAL digital ATC tower, a modular open-architecture system that can run remote or on site and scale into a digital tower center. The technology was developed by Cybernetica in Estonia and first deployed at Kuressaare for EANS; Cybernetica announced the sale of the product and team to Adacel on February 24, 2022, with the development team staying in Tallinn. Adacel and EANS have since commissioned a second digital tower at Kuressaare, and Adacel lists a Fiji Airports award to control Labasa from a remote tower centre in Nadi (date unverified). Adacel and ADB Safegate unveiled an integrated digital tower system at Airspace World 2025.
