Product Description
TDF51IMU0 Fiber Optic Inertial Unit
Dynamic measurement functions for small size and high-precision inertial unit equipment designed for unmanned platforms, water/torpedo weapons, and land/airborne weapon platforms.
Overview
Fiber optic inertial units offer significant advantages including small size, light weight, low power consumption, and high accuracy. These units support pure strapdown, single axis, and dual axis modulation configurations, providing dynamic measurement of carrier angular and linear motion information.

Communication Protocol
- RS422 serial port 1 outputs three channels of angle increment information, three channels of speed increment information, IO count information, and temperature information at 200Hz data frequency
- Raw observation values without interpolation are compensated for errors
- RS422 serial port 2 outputs time synchronization signal at sampling time 1 with valid rising edge
- Pulse width: 10 ± 2 μs, sampling signal interval: 5ms ± 20 μs
- Rising edge and falling edge level establishment time not exceeding 100ns
- Serial port 1 data transmission occurs 50 μs after rising edge emission
Output Data Protocol
- Baud rate: 460800bps
- Output format: RS422, 1-bit start bit, 1-bit stop bit, 8-bit data bit, no checksum
- Data frequency: 200Hz
- All undefined bits are filled with 0 by default
- When transmitting multiple bytes, low byte comes first and high byte comes last
