ZITN NVS910 Inertial Measurement Unit is a reliable Solid-State Inertial and Satellite Navigation IMU. It features a built-in 3-axis silicon gyroscope, 3-axis silicon accelerometer, and a satellite navigation module. The unit undergoes precise calibration on a three-axis turntable to meet performance requirements under various conditions. It delivers real-time, accurate outputs for carrier attitude, position, velocity, and timestamp.
Product Features
- Reliable performance in vibrating environments.
- Precisely calibrated core parameters for both the gyroscope (including bias, bias temperature coefficient, scale factor, scale factor temperature coefficient, misalignment error, and g-sensitivity) and accelerometer (including bias, bias temperature coefficient, scale factor, scale factor temperature coefficient, and misalignment error).
- High-performance satellite navigation module.
- 200Hz strapdown algorithm operation; high-speed sampling ensures detailed motion calculation, suppresses aliasing, and improves signal-to-noise ratio.
- Data output rate up to 200Hz via RS422 interface.
- Low power consumption: Typically 0.12A @5V.
Product Application
Attitude monitoring for UAVs, robotics, and various adaptive navigation vehicles.
