DAIMU 501/701: Tactical IMU Navigation System with Centimeter-Level GPS Accuracy

Cutting-edge tactical-grade all-in-one navigation system engineered for centimeter-level precision positioning across demanding operational environments.

DAIMU 501/701 Tactical IMU Navigation System - Centimeter-Level GPS Accuracy

Advanced Multi-Mode RTK GPS Positioning Technology

The DAIMU 501/701 incorporates sophisticated multi-mode RTK GPS positioning technology that supports GPS, GLONASS, Galileo, BeiDou, and SBAS satellite systems. This ensures reliable centimeter-level RTK accuracy even in challenging signal environments.

The integrated RTK (Real-Time Kinematic) module works in conjunction with the multi-mode satellite positioning system to deliver the absolute positioning precision required by tactical and aerospace applications. This strategic combination enables the GPS IMU navigation system to maintain positioning accuracy during high-dynamic maneuvers and in areas with partial satellite coverage.

Key Advantage: By supporting multiple satellite navigation systems simultaneously, the device ensures robust positioning performance across diverse global regions and operational scenarios.

Integrated High-Precision Tactical IMU Sensor Array

The core of this tactical navigation system lies in its integrated high-precision array IMU (Inertial Measurement Unit), which features ultra-low noise characteristics and excellent bias stability for precise motion tracking.

The tactical IMU provides tactical-grade attitude determination with exceptional reliability during GPS outages or interference conditions. The addition of barometer and magnetometer sensors complements the IMU and RTK GPS data, enabling:

  • Altitude determination relative to mean sea level
  • Absolute heading reference for orientation
  • Continuous attitude tracking during signal gaps
Four Key Datasets Output: Centimeter-level RTK positioning, tactical-grade attitude, absolute heading, and altitude information—all processed internally by the high-performance MCU.

Direct Output and Seamless Platform Integration

The DAIMU 501/701 navigation system excels in direct output capabilities, delivering critical positioning data without requiring complex post-processing algorithms. This direct output functionality enables immediate utilization of positioning, attitude, heading, and altitude information by control systems and autonomy algorithms.

The compact, rugged design facilitates seamless integration into various platforms. The tactical-grade performance maintains superior accuracy under high-dynamic conditions, supporting applications where precision cannot be compromised.

Integration Benefits

The all-in-one design reduces integration complexity and system weight, making it ideal for space-constrained platforms such as small UAVs and autonomous ground vehicles.
