The 3DM-CV7-INS is a tactical-grade inertial navigation system in an extremely compact and lightweight OEM package. Featuring three axes of MEMS accelerometers and gyroscopes as well as an integrated magnetometer, the versatile unit can also optionally accept external position, velocity, and heading inputs from a GNSS receiver.
The 3DM-CV7-INS features advanced auto-adaptive Extended Kalman Filtering and a flexible event triggering system, and is fully calibrated over the entire temperature range. It also provides a number of user-selectable accelerometer and gyroscope measurement ranges.
