• Full-constellation & multi-frequency

The K803 is a full-constellation triple-frequency GNSS OEM board, which tracks GPS, BeiDou, BeiDou Global Signal, GLONASS, Galileo, QZSS, IRNSS, SBAS and L-Band.

• Easy to integrate

The K803 is a 30mm×30mm×3.2mm module with a surface-mounted design, rendering it an optimal choice for users seeking to integrate it into their systems. Its power consumption is notably low, at less than 1.0W.

• INS+GNSS navigation

The K803 is designed with an integrated high-precision inertial measurement unit (IMU) module, which is capable of providing continuous and high-quality positioning data through the use of an inertial navigation fusion algorithm.
