The AARTOS X9 operates with the same precision as the X7, but additionally offers seamless ultra-wideband monitoring with 4+ independent receivers and an optimized amplifier group. The X9 traverses the entire frequency range more than 1000! times per second. With an enormous range of up to 14 km (or much more by scaling multiple AARTOS X9 systems), the AARTOS X9 is perfect for the monitoring of large areas. The system has already proven itself at international airports such as Heathrow and Muscat.
