AEC-Q100 (Grade 2)
This series of full-system, multi-band, high-precision GNSS modules is based on an AEC-Q100 Grade 2 certified, survey-grade RF-baseband integrated chip. Supporting BDS, GPS, GLONASS, Galileo, and QZSS across L1, L2, L5, and L6 bands, it utilizes high-precision full-band raw observables combined with differential data and a built-in RTK algorithm to achieve centimeter-level accuracy within seconds. Optional IMU or dual‑antenna (heading) configurations are available to maintain performance under signal occlusion. Featuring an LGA package and compact size, it meets the demanding requirements of intelligent driving, robotics, and other high‑performance applications.
