Technical manual for the BWSensing GI2200 high‑precision fiber optic navigation system, covering specs, installation, interfaces and communication.
The GI2200 is a high‑performance fiber‑optic integrated navigation system developed by BWSensing for aerospace, UAV, marine and ground applications. It combines a three‑axis fiber gyroscope, three‑axis accelerometer, optional three‑axis magnetometer and high‑precision pressure sensor, and includes a triple‑mode GNSS receiver (BD/GPS/GLONASS).
The manual provides detailed product specifications, mechanical dimensions, installation guidelines, interface definitions, software debugging steps, communication protocol details, and the standards to which the system complies. It also lists contact information for support. This manual is written in Chinese.
| Position accuracy (m) | ≤2m/RTK2cm |
|---|---|
| Attitude angle accuracy (deg) | ≤0.01 |
| Gyro measurement range (deg/s) | ±1000 |
| Accelerometer measurement range (g) | ±10 |
| Operating temperature (°C) | -40~+65 |
| Input voltage (Vdc) | +9~+36 |
| Weight (kg) | 1.5 |
The system requires a zero‑phase measurement type GPS antenna; a standard navigation antenna will greatly reduce accuracy and may cause errors.
It uses RS‑422 at 115200 bps, 8‑N‑1, transmitting 48‑byte navigation data frames at 100 Hz.
The system operates from a DC input of +9 V to +36 V and consumes about 8 W of power.
