Built-in PPP-RTK
Anti-interference & anti-spoofing
1216 LGA package
This full-system, multi-frequency, high-precision GNSS positioning module is built on a 22nm RF baseband integrated GNSS SoC. It supports
multi-frequency reception across all major satellite constellations and, with ASENSING’s integrated RTK algorithm, delivers reliable fix rates and precise positioning even in challenging environments with signal occlusion or weak visibility. With a compact 12mm × 16mm LGA package and versatile external interfaces, the module is fully compatible with mainstream industrial-grade solutions—making it ideal for drones, robotic lawn mowers, and autonomous mobile robots.
