Ruggedized Tactical Grade GPS-Aided Inertial Navigation System 24 марта 2015, 19:34
The 3DM-RQ1™ -45 is a compact, ruggedized, tactical-grade all-in-one navigation solution with integrated GPS and magnetometers, high noise immunity, and exceptional performance. It takes advantage of some of the latest mems sensor technology, exhaustive callibration, and a custom made Kalman Filter to deliver capibillities that rival units that cost many times more.
● High performance integrated GPS receiver and MEMS sensor technology provide direct and computed PVA outputs in a small package.
● Triaxial accelerometer, gyroscope, magnetometer, and temperature sensors, and a pressure altimeter achieve the best combination of measurement qualities.
● Dual on-board processors run a sophisticated Extended Kalman Filter (EKF) for excellent position, velocity, and attitude estimates.
● Ruggedized enclosure designed to meet DO-160G for deployment in harsh environments
The LORD MicroStrain® 3DM-GX4 ® family of industrial grade inertial sensors provides a wide range of triaxial inertial measurements and computed attitude and navigation solutions. In all models, the Inertial Measurement Unit (IMU) includes direct measurement of acceleration, angular rate, and atmospheric pressure. Sensor measurements are processed through a sophisticated estimation filter algorithm to produce high accuracy computed outputs with compensation options for magnetic and linear acceleration anomalies, sensor biases, auto-zero update, and noise offsets. The computed outputs vary between models and can include pitch, roll, yaw, a complete attitude, heading, and reference solution (AHRS) or a complete position, velocity and attitude solution (PVA), as well as integrated GPS outputs. All sensors are fully temperature compensated and calibrated over the operating temperature. The use of Micro- Electro- Mechanical System (MEMS) technology allows for highly accurate, small, lightweight devices.
The LORD MicroStrain® MIP™ Monitor software can be used for device configuration, real time measurement monitoring, and data recording. Alternatively, the MIP™ Data Communications Protocol is available for users who want to develop customized software solutions.
