Rannoch Corp., Alexandria, Va., officially changed its named to Era Corp., reflecting a series of acquisitions made by the company in recent months. In October, the company bought Czech company ERA a.s., which the company said established “one company with the shared goal of leading the world in multilateration and ADS-B [automatic dependent surveillance-broadcast] surveillance technologies.” In December, Rannoch acquired BAE’s TAMIS group to offer its customers a solution that delivers the most accurate flight-tracking data with the most powerful analytical tools for flight and noise analysis. “We are clearly a stronger company with more resources, clear market leadership, and an improved ability to offer the best technology and solutions available in the air traffic control, military and homeland security and airport operations markets,” said Dave Ellison, Era President and CEO.
