IMU-P Tactical - A Navigation Grade IMU

Inertial measurement units (IMUs) are essential components in a wide range of applications, including navigation, stabilization, and attitude heading reference systems (AHRS).navigation grade imu They provide accurate measurements of linear acceleration, angular velocity, and gyroscope data to generate the output required by an application. The market for IMUs is currently snowballing, and Inertial Labs is well-positioned to capitalize on this growth with high-quality products that offer the accuracy, reliability, and ruggedness needed in demanding environments.

Navigation-grade IMUs differ from other types of IMUs in their level of accuracy, stability, and applicable scenarios.navigation grade imu The most appropriate IMU type needs to be selected based on specific application requirements.

The IMU-P Tactical is a navigation-grade IMU that provides excellent performance and accuracy in a rugged package.navigation grade imu It is ideal for use in harsh, GPS-denied environments and can be fused with a single or dual-antenna GNSS receiver to create a robust AHRS. The IMU-P Tactical is designed to withstand the harshest environmental conditions and is ITAR-free, making it suitable for export applications.

Navigation-grade IMUs feature gyroscopes with extremely low bias instability, which allows them to maintain their accuracy over long periods of time.navigation grade imu This capability makes them ideal for precision applications such as drone navigation and antenna and weapon platform stabilization. In addition to having superior accuracy and stability compared to commercial-grade IMUs, navigation-grade IMUs also offer higher reliability owing to their advanced technology and design.

A gyroscope’s output or offset error can be affected by the thermal, physical, and mechanical variations between measured points. These deviations can affect the gyroscope’s overall performance and accuracy, and they can be reduced by applying calibration techniques. These techniques include gyroscope scale factor calibration, accelerometer scale factor calibration, and misalignment correction.

Another important consideration when selecting an IMU is its bandwidth. The bandwidth of a sensor defines how fast it can respond to input and measure output. The higher the bandwidth of an IMU, the greater its performance.

The IMU-P Tactical features a high-performance, wide-band MEMS inertial sensor that offers outstanding accuracy and reliability for the most demanding applications. The sensor’s unique architecture delivers performance similar to fiber optic gyroscopes and RLGs in a much smaller size, weight, and power (SWaP) than other MEMS technologies. This enables Honeywell to deliver an all-silicon MEMS inertial sensor with performance comparable to navigation-grade IMUs at a lower price point. This new MEMS inertial sensor is an ideal solution for high-precision navigation, attitude control, and stabilization applications such as drones and unmanned aerial vehicles (UAVs). The IMU-P Tactical is available now from Honeywell.
