HiPNUC HI71 Tactical-Grade Compact Attitude/INS Module
Vendor: 超核电子 HiPNUC (中国北京)
Product: HI71 战术级紧凑型姿态/惯导模块
HiPNUC (Beijing) HI71 is a tactical-grade compact inertial module in a 24×24×14 mm aluminum case with board-to-board connectors for easy integration. Four variants: T2 (VRU), T4 (AHRS + barometer), M4 (MRU heave) and N4 (INS): gyro ±300 °/s with 0.3 °/h bias instability and 0.0004 °/s√Hz XY noise density; accelerometer ±16 g with 10 μg bias instability; T4/M4/N4 add a ±20 Gauss magnetometer and 300~1200 hPa barometer. Pitch/roll 0.05~0.1°, UART up to 1000 Hz and CAN at 200 Hz, binary/CANopen/Modbus/NMEA protocols with PPS/UTC sync, 3.6~5 V supply at 370 mW.
