High-performance GPS receivers are being used in a wide range of applications requiring automatic, real-time data and system control. GPS receivers process signals from satellite constellions to deliver precise location, velocity, elevation, and timing information services necessary for surveying, mapping, transportation, telecommunications, aviation, agriculture, maritime operations, robotics/UAVs, and emergency response. Today’s GPS receivers are light-years more sophisticated than the old consumer-grade GPS units. The real systems now exist in multi-band or frequency, support multiple GNSS constellations, GPS, GLONASS, Galileo, and or BeiDou, and real-time correction services, e.g., RTK for Real Time Kinematic or PPP for Precise Point Positioning. These features yield sub-foot performance in dense urban canyons, near mountainous terrain, in underground construction sites, or underwater: rates of occurrence. Sectors rely on GPS receivers to enhance productivity, safety, and decision-...

GNSS modules are enabling the development of accurate positioning applications. GNSS (Global Navigation Satellite System) modules are used to receive signals from satellite constellations in orbit around the earth and convert those signals into timed positions. They supply location, motion, and timing information in each of these applications. Compared to a typical GPS receiver, the GNSS module supports more bands and frequencies, the signal robustness in demanding situations is improved, and it can accomplish positioning (relative to carrier) at a decimeter or centimeter level under global RTK/PPP correction sources. Their small size and low power requirements make them ideal for embedded applications where space is limited, and reliability is paramount, such as autonomous vehicles, cars, robots, drones, IoT devices, surveying equipment, marine navigational systems, agricultural machines, and telecommunications infrastructure. The automation, information-based decision-making, and r...
