SkyTraq is offering a 12 x 16 millimeter multi-band real-time kinematic (RTK) receiver for centimeter-level accuracy positioning applications. The PX1122R works with all the four GNSS, using 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, centimeter-level accuracy positioning for autonomous unmanned ground or aerial vehicles, the internet of things, and traditional land surveying and precision farming applications.

The PX1122R 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, the company said.

Moving-base RTK for GNSS precise heading is also supported. By using two PX1122R and two antennas with 1-meter separation, highly accurate 1-sigma heading accuracy of 0.13 degree can be obtained; such heading accuracy is immune to magnetic interference and unaffected by the receiver’s speed.

The PX1122R can serve as a key component to provide precise position and heading information for autonomous applications. PX1122R sample, data sheet and evaluation boards are available now.

Founded in 2005, SkyTraq Technology Inc. develops high-performance chipset and module solutions for the consumer market. Its initial product is L1-GPS-centric, and now its products cover L1, L2, L5, L6 band GPS/GLONASS /Beidou/Galileo/QZSS/NavIC/SBAS applications.
