Mostatechs Mini Gyros Transform Unmanned Systems Industry

When drones operate in complex environments or robots require precise navigation in tight spaces, Size, Weight, and Power (SWaP) become critical factors. The challenge of delivering maximum performance within minimal space has been addressed by MostaTech's innovative VG221 series fiber optic gyros.

MostaTech's latest ultra-compact fiber optic gyro series is specifically designed for applications with stringent SWaP requirements. The VG221 family combines exceptional performance with miniature dimensions, offering significant potential for unmanned systems. The series includes three models: standard VG221, enhanced anti-magnetic VG221MS, and ultra-low noise VG221LN, catering to diverse operational needs.

The VG221 series stands out through its outstanding SWaP characteristics and high-performance metrics:

• Ultra-Compact Design: With dimensions of 33mm diameter and 12mm height, the VG221 significantly saves installation space, facilitating system miniaturization.
• Lightweight: At just 15 grams, it reduces overall system weight, enhancing endurance and payload capacity.
• Low Power Consumption: Operating at only 0.3W, it extends mission duration while reducing power system demands.
• High Performance: The standard VG221 achieves 0.05 °/√h angular random walk (ARW), while the VG221LN model reaches 0.025°/√h for noise-sensitive applications.

A detailed examination of the VG221's key parameters reveals its operational capabilities:

• Input Range: 400°/s covers most unmanned system requirements for angular velocity measurement.
• Bias Stability: 3°/hr ensures long-term operational precision.
• Bandwidth: 1 kHz enables rapid response to dynamic movements.
• Scale Factor: 0.03% maintains output linearity and accuracy.
• Magnetic Field Response: The VG221MS reduces sensitivity to 0.1°/h/Gauss compared to the standard model's 4°/h/Gauss.

The VG221 series' combination of SWaP efficiency and high performance makes it suitable for multiple domains:

• Unmanned Aerial Vehicles: Enhancing attitude control, navigation, and flight stability.
• Ground Vehicles: Supporting autonomous navigation and path planning.
• Robotic Systems: Improving motion control and environmental awareness.
• Space-Constrained Platforms: Including small satellites and wearable devices.

The enhanced anti-magnetic VG221MS incorporates magnetic shielding technology to maintain precision in electromagnetic environments, while the ultra-low noise VG221LN employs advanced signal processing to achieve industry-leading noise reduction for high-precision applications.

This innovative gyro series represents a significant advancement in miniaturized navigation technology, offering tailored solutions for diverse operational requirements across the unmanned systems sector.
