Satellite Navigation <\/h3>\n\n\n\n

Global Navigation Satellite Systems (GNSS) provide worldwide positioning, navigation, and timing services using constellations of satellites orbiting the Earth. By measuring signal travel time from multiple satellites, GNSS receivers can determine precise location and time in real time. These systems underpin a wide range of applications, from transportation and mapping to telecommunications and scientific research.<\/p>\n\n\n\n

        UWB localization<\/h3>\n\n\n\n

        Ultra-wideband (UWB) localization is a positioning technique that uses short radio pulses over a wide frequency spectrum to achieve very high accuracy. Unlike traditional wireless systems, UWB can precisely measure the time it takes for signals to travel between devices, enabling centimeter-level positioning in many environments. This makes it especially useful for applications such as indoor navigation, asset tracking, and robotics, where GPS is often unreliable or unavailable.<\/p>\n\n\n\n

          Multifunction Phased Array Radar (MPAR)<\/h3>\n\n\n\n

          Multifunction Phased Array Radar (MPAR) systems use electronically steered antenna arrays to perform multiple radar tasks\u2014such as surveillance, tracking, and weather monitoring\u2014within a single platform. By rapidly directing beams without mechanical movement, they offer high agility, faster updates, and improved reliability compared to traditional radars. These capabilities make MPAR a key technology for integrated airspace management, defense, and environmental observation. Development of next-generation radar systems capable of multiple simultaneous functions, such as surveillance and weather observation:<\/p>\n\n\n\n

              Noise Radar<\/h3>\n\n\n\n

              Noise radar is a type of radar system that uses random or pseudo-random waveforms instead of traditional deterministic signals for target detection and ranging. By correlating the transmitted and received noise-like signals, it can achieve strong resistance to interference, low probability of interception, and improved performance in complex environments. These characteristics make noise radar attractive for applications requiring stealth, anti-jamming capability, and robust operation in cluttered scenarios.<\/p>\n\n\n\n
