3DM-CV7-INS
Tactical Grade Embeddable Inertial Navigation System
Value-focused embeddable tactical grade inertial navigation system with external position and velocity inputs. Features an advanced Extended Kalman Filter, cutting-edge orientation algorithms, advanced time management, and event triggering system.
Description
The 3DM-CV7 offers tactical grade inertial performance in the smallest and lightest OEM package yet. Each 3DM-CV7 is individually calibrated and features an Adaptive Extended Kalman Filter for optimal performance over a wide range of operating conditions.
All models in the 3DM-CV7 series feature cutting-edge orientation algorithms, advanced internal time management, and a flexible event triggering system. The INS model adds external position, velocity, and heading inputs as well as NMEA compatibility.
With an unparalleled array of advanced features, the 3DM-CV7 sets the benchmark for value and performance in its category.
Key Features of the INS Model: ​
External Position, Velocity, and Heading Inputs: The INS model allows for the integration of external position, velocity, and heading inputs, which improves the accuracy of the position, velocity, and attitude (PVA) estimate of a standalone GNSS receiver. ​
Industry-Standard NMEA Input Over AUX Port: The INS model simplifies GNSS input by providing a configurable AUX port on any of the 4 GPIO ports, allowing for easy integration with industry-standard NMEA protocols. ​
Defense-Ready: The INS model accepts encrypted GNSS receivers (SAASM or MCode), which enhances the reliability of the Position, Navigation, and Timing (PNT) solution during jamming and spoofing events. ​
Filter Body Frame Constraints: The INS model improves position accuracy for known dynamics by applying filter body frame constraints. ​
Body Velocity Inputs and Outputs: The INS model allows users to input measurements in a non-global frame, enabling sensors like radar and vision as aiding sources (with preprocessing). ​
