    1.  OVERVIEW

     

    1.1 Description

    CNT803H-36G is a Real-time Differential (RTD) GNSS receiver with inertial Navigation System (INS). Featuring Ublox single die high performance and low power consumption positioning M8 engine, it provides excellent sensitivity and short TTFF.  CNT803H-36G integrates a BMI055, which is a 6 axis inertial sensor, and powered by a ARM Cortex-M4 MCU+FPU, that allows very low-noise measurement of angular rates and accelerations.

    Relying on the powerful RTD, INS, and GNSS fusion algorithm, CNT803H-36G shows an excellent performance at all terrain scenarios.
