Marconi Research Centre is the former name of the current BAE Systems Applied Intelligence Laboratories facility at Great Baddow in Essex, United Kingdom. Under its earlier name, research at this site spanned military and civilian technology covering the full range of products offered by GEC-Marconi, including radio, radar, telecommunications, mechatronics and microelectronics. The site still includes a prominent local landmark, a 360-foot (110 m)-high (110 m) former Chain Home radar tower visible across the surrounding countryside.
