Tactical Grade Navigation

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 calibration, and a custom made Kalman Filter to deliver capabilities to rival units which cost many times more.


The Inertial Measurement Unit (IMU) outputs include direct measurement of acceleration, angular rate, and atmospheric pressure. Sensor measurements are also 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.

Dual on-board processors run a sophisticated Extended Kalman Filter (EKF) for excellent position, velocity, and attitude estimates (PVA), as well as integrated GPS outputs. The 3DM-RQ1-45 comes built inside a ruggedized aluminium enclosure weighing 205 grams, and is designed to meet DO-160G for deployment in harsh environments.

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. Applications for this device would include GPS aided navigation systems, unmanned vehicle navigation, satellite dish and antenna pointing, and health and usage monitoring of vehicles.

We would be please to discuss any application where this sensor could be used, and if you have any questions regarding inertial measurement in general, we would be pleased to visit you to discuss any possible application.
