This article aims to illustrate the difference in resolution values for key data parameters in Inertial Labs products, including Gyroscope, Accelerometer, Reference Altitude, Reference Position, GNSS Altitude, and GNSS Position data. These parameters play a crucial role in determining the precision and accuracy of the measurements used in various applications such as navigation, robotics, and geospatial mapping.
The table below outlines the measurement units used for each data type and compares the maximum resolution for both Regular and High-Resolution (HR) data modes. Unless otherwise specified, these resolution values apply to all Inertial Labs products—excluding units that do not contain a GNSS receiver.
Importance of Resolution in Inertial Navigation
Resolution in sensor data defines the slightest change in measurement that can be detected and reported by the system. Higher resolution offers increased granularity, improving accuracy in detecting small movements and positional changes. This is particularly crucial in applications where precision is paramount, such as:
- Aerospace and Defense: High-resolution gyroscopes and accelerometers enable accurate inertial navigation for aircraft, drones, and military systems.
- Autonomous Vehicles: Enhanced GNSS resolution helps in precise positioning, improving safety and performance in self-driving systems.
- Geospatial Mapping: Reference altitude and position data with higher resolution facilitate more accurate 3D terrain modeling and mapping applications.
- Industrial Automation: Precise motion tracking ensures better control in robotic arms and automated machinery.
Comparison of Regular and High-Resolution Data
While regular resolution values suffice for many standard applications, High-Resolution (HR) mode significantly enhances data precision. This mode is especially beneficial for users requiring highly detailed motion, altitude, or positional measurements, such as surveyors, engineers, and researchers in precision-based industries.
