The PX1122R is a 12 × 16 millimeter multi-band real-time kinematic (RTK) receiver for centimeter-level-accuracy positioning applications. It uses GPS L1/L2C, Galileo E1/E5b, GLONASS L1/L2 and BeiDou B1I/B2I signals concurrently to maximize positioning availability even in difficult urban environments. A single-chip system-on-chip, the PX1122R is designed to deliver reliable positioning for autonomous unmanned ground or aerial vehicles, the internet of things, and traditional land surveying and precision farming applications. It has an RTK initialization time under 10 seconds and a maximum update rate of 10 Hz. Its update rate provides in-time positioning with a fast response time and improved guidance for fast-moving applications. Moving-base RTK for GNSS precise heading is also supported.
