GNSS Receivers are essential instruments in satellite and space applications, engineered to receive and process signals from Global Navigation Satellite Systems (GNSS) such as GPS, Galileo, GLONASS, and BeiDou. These receivers provide precise positioning, navigation and timing (PNT) data, satellite operations, orbital determination, and mission planning. Integral to satellite-based systems, GNSS receivers enable autonomous orbit control, accurate geolocation and synchronization of onboard systems. Their compact and high-performance design ensures reliability in the challenging environment of space making them indispensable for applications like Earth observation, communication and scientific exploration. Continuous advancements in GNSS technology are enhancing their accuracy and robustness, driving innovation in modern satellite missions. In this article, SATNow has listed some interesting GNSS Receivers that were trending on the website.
