SkyTraq is offering a new multi-band, multi-GNSS receiver module for real-time kinematic (RTK) positioning and heading applications, suitable for autonomous vehicles. The PX1172RH surface-mount receiver measures 17 x 22 mm, about the size of a postage stamp.

With dual-antenna input, the PX1172RH receiver delivers sub-degree heading and pitch or heading and roll angles on top of centimeter-level positioning under both dynamic and static conditions. This removes the dependency on vehicle movement to initialize an inertial measurement unit (IMU) for attitude determination.

The PX1172RH is unaffected by magnetic surroundings and does not require calibration. It offers higher heading reliability and performance than magnetic heading sensors or single-antenna GPS sensors.

The PX1172RH works with dual-frequency GPS/QZSS L1/L2, GLONASS L1/L2, Galileo E1/E5 and BDS B1/B2 GNSS signals concurrently to enable robust positioning and heading performance under challenging partial-sky environments and to provide RTK convergence in seconds. The PX1172RH is suitable for autonomous precision-guidance applications.

A PX1172RH sample, datasheet and evaluation boards will be available in May, with mass production scheduled for June.
