C1 Series

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.
