C1 Series

GNSS High-precision Positioning and Heading Module

Based on Bynav GNSS Baseband ASIC Alita and RFIC Ripley and embedded with Bynav's new generation REAL (Ransac Enhanced Advanced Location) engine, C1 is capable of providing full-constellation and multi-frequency RTK positioning and dual-antenna heading to further optimize the stability of positioning and heading under dynamic conditions.

GNSS Board

C1 can quickly calculate the accurate relative position of antennas and the deviation angle from True North to the line connecting the phase center of two antennas, which is expressed as Heading. Meanwhile, real-time carrier phase differential positioning (RTK) provides centimeter-level high-precision position by receiving correction data from base station.
