K501 OEM Board
 
 

 

ComNav’s K501 GNSS OEM board is the first small-sized GPS+BeiDou OEM board. The K501 has advanced dynamic acquisition ability and high accuracy carrier phase algorithms. By using the dual GNSS constellations, our high dynamic processing engine delivers the results even in very challenging environments for GNSS use. Using the K501, you can achieve centimetre RTK positioning accuracy. The hardware size, interface, data command are designed for compatibility with major brands’ OEM host boards.
