AERONAUTIC SYSTEMS, INC., the Berlin-based company also known as AeroSys, has made an agreement with three of the world's major international airlines to provide a satellite system for voice and data communications, a company spokesperson announced last week. This agreement is a major leap forward for the company, which began operations just three years ago and has now gained the business of three of the airline industry's largest companies. The agreement with Skyways, Air One, and Travelers International will provide communications between aircraft and on-ground systems for operational control and air-traffic services. The agreement was signed last month, and AeroSys will begin providing services to the airlines before the end of the year. Where is AeroSys based?
