Micro Magic, a provider of high-precision inertial sensing solutions, has released three new Ring Laser Gyroscope (RLG) models, the G-R90, G-R70 & G-R50, engineered for demanding high-precision Inertial Navigation Systems (INS) & unmanned platforms.
Combining proven solid-state design with advanced manufacturing and temperature compensation technologies, the new RLG series delivers exceptional stability, reliability, and flexibility, addressing diverse performance and Size-Weight-Power (SWaP) requirements across commercial, industrial, and defense applications.
All three RLG models leverage the optical Sagnac effect to measure angular velocity in real time, eliminating moving parts for enhanced durability and long service life.
Key features include:
- Rapid Startup: High-voltage starter control ignites the gyroscope in ≤5s, ensuring quick deployment for time-sensitive missions.
- Robust Environmental Tolerance: Solid-state construction resists shock and vibration, while the -40~+70℃ operating range meets global environmental demands.
- Seamless Integration: Standard RS422 communication interfaces (115200 bps, 8-bit data, 1 start/stop bit, no parity) support dual operating modes: Regular mode (100Hz automatic data upload) & Test mode (1Hz upload + parameter read/write), simplifying integration with existing INS and control systems.
- Mechanical Flexibility: Customizable external interfaces (3×M5 screws for G-R90; 4×M3 screws for G-R70/G-R50) and expandable electrical pins, via J30JM-25ZKP37L connectors, adapt to diverse installation requirements.
G-R90
The G-R90 serves as the flagship model, establishing a new standard for precision with zero bias stability of ≤0.002 °/h (1σ) and zero bias repeatability of ≤0.002 °/h (1σ), delivering accuracy for advanced INS used in aerospace, geospatial mapping, and defense applications.
Its stable scale factor (error ≤5 ppm) and advanced temperature compensation technology minimize drift under extreme conditions, while a -40 to +70℃ operating range and solid-state architecture provide excellent resistance to shock and vibration. The G-R90 weighs 1750±50 g (147 × 125 × 57 mm) and consumes less than 4 W of power, featuring a maximum input angular rate of ±400 °/s and a startup time of ≤5 s, making it ideal for mission-critical systems where precision is paramount.
G-R70
The G-R70 achieves an optimal balance between precision and practicality, offering zero bias stability of ≤0.004 °/h (1σ) and a fixed scale factor of 3.422 arc-seconds per pulse (scale factor error ≤10 ppm).
Designed for mid-tier INS and unmanned platforms such as UGVs and UAVs, it supports a maximum input angular rate of ±800 °/s and flexible shaking frequency bands (520–550, 570–600, 640–670 Hz) for reliable performance in dynamic motion environments. Weighing 950±15 g (102 × 93 × 54 mm) with power consumption below 5 W, the G-R70 integrates easily into systems that demand both accuracy and moderate SWaP, including platform stabilization and autonomous logistics applications.
G-R50
The G-R50 redefines compact precision, weighing only 380±15 g (72 × 72 × 48.1 mm), making it one of the smallest high-performance RLGs available. Despite its compact size, it delivers zero bias stability of ≤0.007 °/h (1σ) and features the same 3.422 arc-seconds per pulse scale factor and ±800 °/s maximum input angular rate as the G-R70.
Operating with shaking frequency bands of 550–570, 620–650, and 690–720 Hz and power consumption below 5 W, the G-R50 is purpose-built for SWaP-constrained platforms such as small drones (sUAVs), Autonomous Underwater Vehicles (AUVs), and portable survey systems, enabling high-precision navigation in space-limited environments.
Industry Applications
The new RLG series addresses unmet needs in sectors ranging from defense to agriculture:
- Defense & Aerospace: High-precision INS for military UAVs, guided systems, and satellite ground stations.
- Autonomous Transportation: Navigation and motion control for self-driving trucks, mining vehicles, and port logistics robots.
- Environmental & Survey: Geospatial mapping, precision agriculture (drone seeding/spraying), and offshore AUV inspections.
- Industrial Stabilization: Camera and sensor stabilization for aerial surveillance, construction equipment, and marine platforms.
Each model retains Micro Magic’s core advantages, rapid startup, wide dynamic range, and robust environmental tolerance, while offering unique specifications to target specific use cases.
