Features

Support BDS-3, BDS-2, GPS, GLONASS, Galileo, QZSS, L1/L5 bands
Internal adaptive anti-interference algorithm
Small size, 12mm×16mm
Surface-mounted design to integrate
On board IMU
0.15W low power consumption

Dual-band & multi-constellation

K801 adopts high-precision Soc chip and supports BDS-3, GPS, BDS-2, GLONASS, Galileo, QZSS and L1/L5 dual-frequency signals, which can significantly reduce signal acquisition when interrupted and improve positioning accuracy

INS+GNSS navigation

K801 is designed with an onboard high-precision IMU module, which can provide continuous and high-quality positioning data with inertial navigation fusion algorithm.

Easy to Integrate

Featuring surface mounted design, smaller size of 12mm × 16mm and low power consumption, K801 is compatible with mainstream GNSS modules, allowing users to integrate more easily.
