Air navigation service providers (ANSPs) require a surveillance solution capable of addressing the serious risk of runway incursions and ground vehicle surveillance in critical areas. GSA – Ground Surveillance Automation – provides surveillance of aircrafts and ground vehicles required for surface movement surveillance as well as advanced surface movement guidance and control systems (A- SMGCS) to ensure safe and efficient operations at any airport. A-SMGCS combines mature multi-alteration technology with Surface Movement Radar (SMR). A-SMGCS provides enhancement for low visibility operations as well as for day-to-day operations by increasing safety and capacity.
