CLAP-B7

High Precision GNSS/INS Board

Brief Introduction

ClapTM(Concurrent Localization & Attitude Pilot) is a high-precision multi-sensor fusion positioning and heading technology developed by Unicore Communications. By using the latest "CLAP" technology. Unicore has launched CLAP series products, characterized as the miniaturized and high-performance intergrated boards. Based on multi-mode and multi-frequency, dual-antenna positioning and orientation, high-precision GNSS board, and integrated MEMS intertial measurment unit, the CLAP series products provide low-latency, high precision three-dimensional position, velocity, attitude, IMU original acceleration and angular velocity measurement results. Even when the GNSS signal is completely blocked, the performance remains stabel and continuous, by combining the absolute accuracy of GNSS positioning and the reliability of inertial measurement.

The CLAP series products have the fucntions of moving base alignment, inertial/satellite combined navigation, independent zero speed correction, independent calibration and many more. It can be combined with the odomenter date to further improve the accuracy of vehicle navigation.

All the settings and data collection can be completed by using simple commands and data recording interface via the standard serial port. Once the hardware is installed, the system cna be set up within a few minutes

CLAP-B7 is a compact size, light wight, low power consumption, low cost, user-friendly intergration and mass production OEM board, designed for automatic driving, traverse measurement, unmanned serial vehicles and various attitude stabillization platforms.
