K501 OEM Board|GNSS 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.

· GPS L1/L2+BeiDou B1/B2/B3 dual satellite system calculating

· Configurable GPS/BeiDou single system positioning and GPS+BeiDou dual system positioning

· Compatible with other major brands on physical size, interface and data command

· Supports long baseline E-RTK¹

· Easy to customize

· Built in 100M internal memory
