GPS2B SAR (Geostationary Positioning and Surveillance Radar) is an advanced radar system developed and deployed by General Electric (GE). It is designed to help create an optimal system for airport surveillance and basic airspace control. This system contains two primary components: a geo-positioning portion and the surveillance radar. The positioning portion includes a set of GPS receivers and antennas, allowing for the accurate determination of aircraft position and identification. The radar is an SAR (Synthetic Aperture Radar) system, which uses multiple reflectors, wide-band micro-wave pulses, and narrow beams to provide 3D higher-resolution imaging of aircraft and other airborne objects. Both components work together to provide live, high-accuracy real-time data for tracking and monitoring air traffic. By utilizing this system, airports and air traffic controllers can receive data in a much more accurate and efficient way, leading to safer operations and improved airspace utilization.
